Huang, Zihan;Yin, Claire;Corrado, Tanner;Li, Si;Zhang, Qinnan;Guo, Ruilan research published 《 Microporous Pentiptycene-Based Polymers with Heterocyclic Rings for High-Performance Gas Separation Membranes》, the research content is summarized as follows. Microporous polymers, such as polymers of intrinsic microporosity (PIMs) and thermally rearranged (TR) polymers, have shown promise in advancing the performance of polymer gas separation membranes to overcome the permeability-selectivity trade-off. In this work, a series of thermally rearranged pentiptycene-based polybenzoxazole (PPBO) polymers were prepared from a new pentiptycene-based poly(o-hydroxyl imide) (PPHI) precursor using carefully designed thermal protocols. Fundamental structure-property relationships within the series were established by comprehensively examining the effects of intermediate treatment temperature and the heating rate on the membrane microporosity, properties, and gas separation performance. The incorporation of bulky pentiptycene units into TR PPBO structures, along with optimized TR thermal protocols in this study, provided a route to finely tune and eventually maximize the separation performance of PPBOs, with several films far exceeding the 2015 upper bound for H₂/CH₄ and O₂/N₂. In CO₂/CH₄ mixed-gas permeation tests, PPBO membranes showed excellent resistance to plasticization under CO₂ partial pressure as high as 6.6 atm, far surpassing the 2008 mixed-gas upper bound for CO₂/CH₄. Moreover, a 5 mo aged PPBO film maintained its superior separation performance above the 2008 O₂/N₂ upper bound and 2015 H₂/CH₄ upper bound, indicating the excellent aging resistance of PPBOs.

Hu, Jianghuai;Xie, Huanxin;Zhu, Zhengzhu;Yang, Wenjie;Tan, Wei;Zeng, Ke;Yang, Gang research published 《 Reducing the melting point and curing temperature of aromatic cyano-based resins simultaneously through a Bronsted acid-base synergistic strategy》, the research content is summarized as follows. High m.ps. (M_p) and high curing temperatures are two key processing problems that limit the application of aromatic cyano-based (AC) resins. A Bronsted acid-base synergistic strategy based on an acid-base eutectic and mechanisms for nucleophilic addition and ionization equilibrium are proposed to reduce the M_p and curing temperature of AC resins. Blends of 4,5-dicyanoimidazole (DCI, Bronsted acid) and amine-containing phthalonitriles (4 or 2 or 3)-aminophenoxy phthalonitrile, APNs, Bronsted bases were selected as model acid-base systems to study the synergistic behaviors in processing. The results show that the M_p and the peak exothermic temperature (T_rp) of APN-DCI blends can be reduced by more than 31°C and 85°C compared with their intrinsic components, resp. DSC and XRD show that the decrease in the Mp of the blends is induced by the formation of eutectics. A pos. relationship between pKa and the curing reactivity is confirmed by theory and exptl. methods. The cured products show outstanding thermal and mech. properties compared with reported AC resins. This research provides a new convenient route for regulating the curing behavior of AC resins and will significantly promote the development of high-performance AC resins.

Hu, Meng-Ke;Zhou, Shenghua;Ma, Dong-Dong;Zhu, Qi-Long research published 《 New insight into heterointerfacial effect for heterogenized metallomacrocycle catalysts in executing electrocatalytic CO₂ reduction》, the research content is summarized as follows. The heterogenized metallomacrocycles with atomically dispersed active sites are identified as the promising candidates for electrocatalytic CO₂ reduction reaction (CO₂RR), where their unique heterointerface with interaction between sp² carbon and macrocyclic mols. is important but remains vague. Herein, based on well-structured nickel phthalocyanine and porphyrin with the same functional groups (MeNiPc and MeNiPp), the influences of heterointerfacial effect on catalytic performances are systematically disclosed. Through the mol. structure-induced self-adaptive adsorption with optimized heterointerfacial distance, MeNiPc/graphene reveals a high CO Faradaic efficiency of ∼99% in a wide potential window, greatly outperforming the MeNiPp/graphene counterpart (≤29.6%). Detailed measurements and theor. calculations decipher that the higher CO₂RR activity of MeNiPc/graphene is attributed to the unique electronic structures of the Ni-N₄ configurations suitable for well-suited heterointerfacial charge transfer and rapid CO desorption. Addnl., the extended research confirms the universality of heterointerface engineering on boosting the catalytic performances.

Hu, Meng-Ke;Wang, Ning;Ma, Dong-Dong;Zhu, Qi-Long research published 《 Surveying the electrocatalytic CO₂-to-CO activity of heterogenized metallomacrocycles via accurate clipping at the molecular level》, the research content is summarized as follows. Heterogenized phthalocyanine-based mol. catalysts are the ideal electrocatalytic platforms for CO₂ reduction reaction (CO₂RR) because of their well-defined structures and potential properties. In addition to the pursuit of catalytic performances at industrial potentials, it is equally important to explore exptl. rules and design considerations behind activity and selectivity. Herein, we successfully developed a series of nickel phthalocyanines (NiPcs) with different alkyl chains immobilized on multi-walled carbon nanotubes (CNT) to unveil the structure-performance relationship for electrocatalytic CO₂RR in neutral electrolyte. Interestingly, a volcano-type trend was found between the activity for CO₂-to-CO conversion and alkyl chain lengths of NiPcs on CNT. Exptl. results further indicate that their electrocatalytic CO₂RR activities are highly related to the mol. dispersion and the heterointerfacial charge transfer capability adjusted by the alkyl chains. Particularly, the optimized electrocatalyst via accurate clipping at the mol. level exhibits an ultrahigh activity with Faradaic efficiency of CO up to 99.52%.

Guzel, Emre;Atmaca, Goknur Yasa;Kuznetsov, Aleksey E.;Turkkol, Aysegul;Bilgin, Mehmet Dincer;Erdogmus, Ali research published 《 Ultrasound versus Light: Exploring Photophysicochemical and Sonochemical Properties of Phthalocyanine-Based Therapeutics, Theoretical Study, and In Vitro Evaluations》, the research content is summarized as follows. Photodynamic therapy (PDT) applications carried out with the assistance of ultrasound have attracted significant attention in recent years. The use of phthalocyanines, which are an important component as photosensitizers in PDT, is becoming more important day by day. In therapeutic applications, phthalocyanines can promote the production of reactive oxygen species. Motivated by this fact, the syntheses of metal-free (2), gallium (3), and indium (4) phthalocyanines have been achieved by substituting 4-(cinnamyloxy)phthalonitrile for the first time to evaluate their therapeutic applications. Addnl., photophysicochem., sonophotochem., and in vitro evaluations of phthalocyanines have been reported. To the best of our knowledge, this is the first study of the use of phthalocyanines with different metal ions as potential photosensitizers for sonophotodynamic therapy (SPDT) applications in gastric cancer cell lines. The results show that the quantum yield of the generation of singlet oxygen increased in sonophotochem. studies (Φ_Δ = 0.55 (2), 0.85 (3), 0.96 (4)), compared to photochem. studies (Φ_Δ = 0.22 (2), 0.61 (3), 0.78 (4)). The d. functional theory (DFT) results are in good agreement with the exptl. results and suggest increased reactivity of phthalocyanines 3 and 4 in various redox processes, thus implying their applicability and usefulness as potential therapeutic agents. These phthalocyanines are effective sensitizers for PDT, sonodynamic therapy (SDT), and SPDT against MKN-28 gastric cancer cell line in vitro. All three treatments decreased cell viability and induced apoptosis in the gastric cancer cell line. However, indium phthalocyanine (4)-mediated SPDT was a more effective treatment modality compared to indium phthalocyanine (4)-mediated PDT and SDT. Also, indium phthalocyanine (4) was found to be a more effective sensitizer to activate apoptosis compared to the other phthalocyanines. To sum up, phthalocyanine-mediated SPDT enhances the cytotoxic effect on gastric cancer cells more than the effect of SDT or PDT alone.

Hadimane, Sowmyashree;Aralekallu, Shambhulinga;CP, Keshavananda Prabhu;Hojamberdiev, Mirabbos;Sannegowda, Lokesh Koodlur research published 《 Bioinspired Precious-Metal-Free N4 Macrocycle as an Electrocatalyst for the Hydrogen Evolution Reaction》, the research content is summarized as follows. The design and development of strategies and catalysts are essential for sustainable energy production, particularly for the hydrogen evolution reaction (HER). Precious Pt/C catalyst is known to demonstrate high efficiency in the electrochem. HER and suffers from commercialization issues. Therefore, precious-metal-free and organic-based catalysts are of importance for a future perspective. In this work, cobalt tetra[4-[2-(1H-benzimidazol-2-yl)phenoxy]]phthalocyanine (CoTBImPc) is synthesized for the first time and characterized by physicochem. and electrochem. techniques. ¹H NMR and mass spectral data reveal the successful formation of the ligand and complex, whereas the thermogravimetry (TG) study confirms the thermal stability of the complex up to 400 °C. The electroactivity of CoTBImPc is compared with the hybrid composite of a carbon nanotube (CNT-CoTBImPc) and benchmark Pt/C catalyst for the HER. Linear sweep voltammetry (LSV) shows that an onset potential for the HER for CoTBImPc-CNT/GCE is shifted to a higher potential than that of CoTBImPc/GCE, suggesting that the HER is more feasible at the surface of CoTBImPc-CNT. Higher activity for CoTBImPc-CNT/GCE in comparison with that of CoTBImPc/GCE in 0.5 M H₂SO₄ (pH = 0.3) may be ascribed to the enhanced conductivity, a greater number of active sites, and a larger surface area. The hybrid composite yields a c.d. of -10 mA·cm^-2 and demonstrates HER activity at a lower overpotential (63 mV). The benchmark Pt/C catalyst and the as-synthesized pristine phthalocyanine mol. exhibit the HER at overpotentials of 3 and 160 mV, resp., at a c.d. of -10 mA·cm^-2. A lower Tafel slope value of 43.2 mV·dec^-1 and a higher double-layer capacitance value of 44 mF·cm^-2 confirm that the hybrid composite is one of the superior catalyst candidates for the HER compared to the bare glassy carbon electrode (GCE) and pristine metal phthalocyanine. Further, CoTBImPc-CNT/GCE also exhibits an excellent stability during the HER.
