“…Similar observations were reported in the literature. [46][47][48][49] For example, a glass transition domain centered at 39°C was observed for polyazomethine derived from 2,5-bis(n-dodecyloxy)terephthaldehyde and para-phenylene diamine. [46] The Cu and Co polymeric complexes exhibited similar T g values of 65.00 and 67.51°C, higher than the T g value of the starting polymer.…”

A new dialdehyde-containing silicon was prepared by a reaction of Williamson-type and structurally characterized. By its subsequent condensation with 2,5-bis(p-aminophenyl)-1,3,4-oxadiazole, a multifunctional polyazomethine-containing imine, phenylene, oxadiazole, ether, and carbosilane groups within the chain was prepared. The complexes of this polymer with Co(II), Cu(II), and Zn(II) ions formed on the basis of electron-donor ability of the oxadiazole and azomethine groups were prepared in a one-step approach by mixing the two precursors of polyazomethine (dialdehyde and diamine) with corresponding metal salt. The ligand and metal complexes were characterized by spectral (Fourier transform infrared (FTIR), 1 H, and 13 C NMR) methods. The thermal, optical, electrochemical, and dielectric properties were studied and the effects of the metal insertion in dependence on its nature over these properties were evaluated. All compounds are soluble in common organic solvents and show low glass transitions due to the flexible ether and Si-C bonds, are fluorescent, mainly due to the oxadiazole ring, are redox active and have high dielectric constant due to the presence of oxadiazole, azomethine metal units.

“…4‐[4′‐(Hydrazinocarbonyl) phenoxy]‐2‐pentadecylbenzohydrazide (HPPB) was synthesized from cashewnut shell liquid (CNSL) using a procedure previously described 21–23. Terephthalic acid chloride (TPC) and isophthalic acid chloride (IPC) were synthesized from terephthalic acid and isophthalic acid (Aldrich, USA), respectively, using excess thionyl chloride in the presence of N , N ‐dimethylformamide (DMF) as a catalyst.…”

“…This is possibly attributed to the fact that typical aromatic PODs are difficult to process due to their infusible and insoluble nature as well as their brittleness. Many efforts have been made to improve the processability by incorporating flexible linkages in the polymer backbone or by the introduction of bulky pendant groups on the aromatic rings 21–23. Herein, we report electrochemical switching of fluorescence of alkyl‐substituted PODs, in which oxadiazole units are connected in the para‐ (POD‐1) or, meta‐ position (POD‐2) of the aromatic linkage in the main chain of the PODs.…”

A highly soluble poly(1,3,4-oxadiazole) (POD) substituted with long alkyl chains was examined for electrochemical fluorescence switching. The high solubility of the polymers enabled a simple fabrication of an electrochemical cell, which showed reversible fluorescence switching between dark (n-doping) and bright (neutral) states with a maximum on/off ratio of 2.5 and a cyclability longer than 1000 cycles. Photochemical cleavage of the oxadiazole in POD allowed photo-patterning of the POD film upon exposure to UV source. The patterned POD films displayed patterned image reversibly under a step potential of +1.8/-1.8 V.
