Xiao, Hang published the artcileA High-Mechanical-Strength Carbon/Graphene Porous Composite with Improved EMI Shielding Derived from High Nitrogen-Containing Bio-based Adenine-Containing Phthalonitrile Resin, COA of Formula: C8H4N2, the main research area is carbon graphene porous composite EMI shielding mech property.

Abstract: Nitrogen-doped porous graphene/adenine-containing phthalonitrile (graphene/ADCN) carbon composites with excellent mech. properties and electromagnetic interference (EMI) shielding performance were prepared by the high-energy ball milling molding-sintering method. The structure, morphol., elec. conductivity, dielec. properties, EMI shielding performance, and mech. properties were characterized. The results show that the introduction of the dipole effect can confer improved elec. conductivity and EMI shielding properties to graphene/ADCN carbon composites. The porous structure increases the multiple reflections and improves the EMI performance. As a mech. reinforcement phase, graphene was introduced to maintain the porous structure and improve the mech. properties. The EMI performance of graphene/ADCN carbon composites reached 47dB (7.5wt.% graphene) with only 0.94 mm thickness. Meanwhile, the maximum bending stress reached 292 MPa, and the maximum compressive stress reached 143 MPa. Graphical Abstract: [graphic not available: see fulltext].

Tejerina, Lara published the artcileOne-Pot Synthesis of π-Extended Fluorenone-Fused Subphthalocyanines, Category: nitriles-buliding-blocks, the main research area is fluorenone fused Subphthalocyanine.

A family of inherently chiral nonplanar aromatic chromophores, comprising Subphthalocyanines bearing fluorenone-fused units (SubFcs), were prepared by an innovative one-pot synthesis, which relies on the standard cross-cyclotrimerization of phthalonitriles followed by intramol. Friedel-Crafts acylation. Their Q-band absorption experiences a ca. 20 nm red shift per fused fluorenone as a consequence of the enlarged conjugated π-system.

Liu, Limin published the artcileGroup IIA alkaline-earth metal phthalocyanines: Synthesis, photoluminescence and singlet oxygen formation, Computed Properties of 91-15-6, the main research area is metallophthalocyanine fluorescence lifetime singlet oxygen formation.

We have synthesized Group IIA alk.-earth metal phthalocyanine (PC) complexes (BePC, MgPC, CaPC, SrPC, BaPC) using four different methods to study their photoluminescence and singlet oxygen photosensitizing properties. Their UV-Vis electronic absorption, fluorescence emission and excitation spectra, fluorescence quantum yields and lifetimes, as well as singlet oxygen formation quantum yields have been measured. The results reveal that alkali-earth metal PCs (BePC, MgPC, CaPC, SrPC, and BaPC) have high fluorescence quantum yields (0.50 to 0.70) and long fluorescence lifetimes (7.1 to 7.9 ns). SrPC, and BaPC also show high quantum yield of singlet oxygen formation (0.40 to 0.50). Therefore, alk.-earth metal phthalocyanines are appealing fluorescent sensors and singlet oxygen photosensitizers for photodynamic therapy of tumors.

Galstyan, Anzhela published the artcileExploring the Impact of Coordination-Driven Self Assembly on the Antibacterial Activity of Low-Symmetry Phthalocyanines, COA of Formula: C8H4N2, the main research area is phthalocyanine coordination driven self assembly antimicrobial photodynamic therapy; antimicrobial photodynamic therapy; bacterial biofilm; pH-responsiveness; phthalocyanine; self-assembly.

Understanding the action mechanisms of self-assembled photosensitizers is very important to determine the requirements that constructing monomers should fulfill to obtain nanostructures with the desired function. Here, the synthesis, supramol. aggregation tendency, photophys. properties and antimicrobial photodynamic activity of low symmetry metal-free phthalocyanine is carefully examined and compared with its metalated counterpart. When exposed to the media with different pH values striking differences in the self-assembly of these two derivatives were observed Equilibrium between active and inactive forms of this unique supramol. system were shifted upon change of the microenvironment influencing its biol. activity against Gram-pos. and Gram-neg. bacteria in planktonic and biofilm state. DFT calculations helped to explain possible differences in the aggregate formation, showing that metal-ligand interaction is a key process behind the higher activity of metalated derivative These results point out the importance of intermol. interactions between photosensitizers, which is essential to guide the design of self-assembled phototheranostic agents with improved performance.

Martin-Biosca, Yolanda published the artcileMonod-based ‘single-data’ strategy for biodegradation screening tests, Safety of Phthalonitrile, the main research area is biodegradation single data strategy Monod kinetics simulation.

Obtaining biodegradation data over time can be difficult, especially when dealing with environmental compartments of increasing complexity. We evaluated the possibility of obtaining a full biodegradation depletion curve from a single biodegradation-time exptl. measurement, and found that environmental information related to potential chem. persistence can be derived. In these tests, the removal of the tested compound is measured over a prefixed period of time (e.g. 28 days in ready biodegradability tests) to derive a substrate depletion curve. The implementation can be time-consuming, costly and difficult, especially when the complexity of the environmental compartment increases. In this work, the possibility of obtaining a full biodegradation depletion curve from a single biodegradation-time exptl. data point (‘single-data’ strategy) was evaluated. Monod kinetics are assumed to avoid the limitations related to first-order kinetics (only valid for very low substrate concentrations). The effects on the estimates of several variables (e.g. Monod kinetics parameters, compound concentration or variability in biodegradation data) and the errors introduced to some of the variables were also evaluated. The applicability and practical limitations of the ‘single-data’ strategy have been illustrated using exptl. data for several compounds ranging from readily biodegradable (e.g. benzoic acid, acetylsalicylic acid, p-toluic acid) to potentially persistent compounds (e.g. bupivacaine, p-phenitidine, phtadinitrile).

Yilmaz, Yusuf published the artcileSynthesis and spectroscopic characterization of new phthalocyanine derivatives: application as photocatalysts for the degradation of Orange G, Formula: C8H4N2, the main research area is phthalocyanine photocatalyst OrangeG degradation.

New derivatives of 2(3),9(10),16(17),23(24)-tetrakis-(6-methylpyridin-2-yloxy)phthalocyanine (Pc) (2b, 2c, and 2d) were synthesized and their structures were characterized by elemental anal., IR, 1 H NMR, and high-resolution mass spectrometry. The spectral results were in line with the proposed structures. The photodegradation of Orange G (OG) dye in DMSO by the Pc derivatives was investigated. The compounds showed relatively high photodegradation rates that increased with increasing size of the central atoms. The Pc photodegradation rates showed fair correlation with the singlet oxygen generation efficiencies (φΔ) . The observed rate constants were higher than the values already reported for other Pcs in the literature for the photodegradation of OG in aqueous media.

Huang, Peng published the artcileAsymmetrically Substituted Phthalocyanines as Dopant-Free Hole Selective Layers for Reliability in Perovskite Solar Cells, Safety of Phthalonitrile, the main research area is metal phthalocyanines perovskite solar cell.

Dopant-free metal phthalocyanines are viable alternatives to the classical 2,2′,7,7′-tetrakis-(N,N-di-p-methoxyphenylamine)-9,9′-spirobifluorene (Spiro-OMeTAD) in perovskite solar cells (PSCs), due to their appealing optoelec. properties and chem. stability. However, low carrier concentration, transportability, and narrow band gap limit their application. Here, we designed and investigated six innovative asym. substituted metal phthalocyanines (MPcs, M = Zn or Cu), and established the correlation among the electronic structure, charge carrier transfer parameter, and core metal/substitutions in MPcs by transient absorption spectroscopy and ESR. We probed the charge transport properties of ZnPcs including their carrier lifetime, diffusion coefficient, and diffusion length by transient absorption spectroscopy. We noted that ZnPcAE presents a longer diffusion length (1.94 nm) than the control ZnPcTB4 (0.80 nm), which is advantageous for reducing charge recombination and gives a higher power conversion efficiency in the fabricated PSCs. Importantly, the devices with MPcs yielded improved stability under multistress conditions. Our work provides a mol. guideline for designing MPcs and their application as dopant-free hole-transporting materials for perovskite solar cell fabrication.
