The authors synthesized peripherally tetra-({6-[3-(dimethylamino)phenoxy]hexyl}oxy) substituted water-soluble metallophthalocyanines (DM-C6-CoQ, DM-C6-CuQ, DM-C6-MnQ) and studied their in vitro cholinesterases inhibitory properties by using the spectrophotometric method. The compounds inhibited cholinesterases and had remarkable inhibitory effects when compared with galantamine (p < 0.0001). The IC₅₀ values of the compounds ranged from 2.11 ± 0.20 to 16.40 ± 1.25μM for AChE and BuChE. Also, the inhibitory type and inhibition constant (K_i) of the compounds were evaluated using Lineweaver-Burk and Dixon plots. These plots showed that DM-C6-CoQ, DM-C6-CuQ, and DM-C6-MnQ were mixed inhibitors against AChE and DM-C6-MnQ is the strongest binding inhibitor to the enzyme. Also, DM-C6-CoQ inhibited BuChE via competitive manner with 10.05 ± 0.55μM of K_i value. The compounds might be effective agents against Alzheimer’s disease.

Butler, Tristan;Bunton, Caleb;Ryou, Heonjune;Dyatkin, Boris;Weise, Nickolaus;Laskoski, Matthew research published 《 Influence of molecular weight on thermal and mechanical properties of bisphenol A-based phthalonitrile resins》, the research content is summarized as follows. This effort assesses the correlation between chem. structures and performance-essential thermal, mech., and long-term stability properties of cross-linked thermosets. Resins of different mol. weights were prepared from the Bisphenol A based PEEK-like oligomeric phthalonitrile (BisA). Differential scanning calorimetry, which was used to investigate curing thermodn., indicated that BisA resins demonstrated pos. correlation between increasing oligomer mol. weight and both resulting m.ps. and cure initiation conditions. Characterization of thermal properties using thermogravimetric anal. (TGA) indicated a similar mol. weight trend, with char yields ranging between 57% and 73%. Rheol. studies of BisA of different mol. weights indicated significant viscosity increases in phthalonitriles that crosslinked from oligomers with higher mol. weights Moreover, the n = 1 chain length resin exhibited a gel point at 100°C lower than the n = 25 oligomer. Anal. of hardness of these cured polymers indicated that the resin crosslinked using the n = 1 oligomer was most brittle, while the thermoset derived from the n = 4 BisA demonstrated highest hardness. Aging of cured phthalonitriles indicated that the n = 10 remained most stable in long-duration high-temperature environments. This study suggests the use of preparing BisA thermosets from oligomers with different mol. weights as an effective strategy for improving toughness, albeit at the tradeoff of lower thermal stabilities.

Cavus, Aleyna;Gork, Gulsen;Erdem, Murat;Ozer, Metin research published 《 Synthesis and characterization of the novel 4-(1-(pyridin-4-yl) ethoxyl) substituted bis(phthalocyaninato) rare earth complexes and investigation of their two-photon absorption-based third-order non-linear optical properties》, the research content is summarized as follows. Novel 4-(1-(pyridin-4-yl) ethoxyl) substituted double-decker rare earth phthalocyanine complexes were synthesized starting from (R)-4-(1-(pyridin-4-yl) ethoxy) phthalonitrile with proper rare earth metal acetates in octanol catalyzed by 1,8-diazabicyclo[5.4.0]undec-7-ene at 300°C. The new starting phthalonitrile compound was obtained from (R)-1-(pyridin-4-yl) ethan-1-ol and 4-nitrophthalonitrile in acetonitrile at reflux temperature in the presence of potassium carbonate as a catalyst. The characterization of the synthesized and isolated compounds was performed by elemental anal., IR, UV-visible, proton and correlation spectroscopy NMR, and matrix-assisted laser desorption/ionization time-of-flight mass spectroscopic methods. Nonlinear optical responses of all complexes are investigated using the Z-scan method. The nonlinear absorption coefficient, two-photon absorption cross-section, and the imaginary part of the nonlinear susceptibility of complexes are calculated for each discrete concentration All these nonlinear parameters of our rare-earth coordinated double-decker phthalocyanines present a decrement due to the aggregation under high optic powers, which result in sequential two-photon absorption for smaller ionic radii.

He, Liang;Tong, Lifen;Bai, Zhongxiang;Lin, Guo;Xia, Yunqing;Liu, Xiaobo research published 《 Investigation of the controllable thermal curing reaction for ultrahigh T_g polyarylene ether nitrile compositions》, the research content is summarized as follows. High-performance polymer plays critical roles in 5G communication and electronic applications. Hence, special engineering plastic polyarylene ether nitrile (PEN) suitable for use in a harsh environment (T_g > 400°C,T_5% > 500°C, and tensile strength 100 MPa) has been developed. Bisphthalonitrile (BPh) units form a flexible bridge between the nitrile of PEN. In the preparation, DDS acts as a catalyst and ZnCl₂ functions as both a catalyst and a reinforcing phase, to enhance the degree of crosslinking and mech. properties of the resulting compositions Therefore, the structure of a linear polymer is converted into a 3D network, resulting in greatly enhanced performance. The mode of action for DDS/ZnCl₂ and the transformation of nitrile groups has been described. These insights provide an understanding of the impact of crosslinking factors in structure formation and supply a feasible design strategy for the preparation of high-performance polymer films.
