New electroactive and electrochromic aromatic polyamides with ether-linked bis(triphenylamine) units

A new class of electroactive polyamides with etherlinked bis(triphenylamine) [O(TPA)2] units were prepared through the direct phosphorylation polycondensation from N,N-di(4-aminophenyl)-N′,N′-diphenyl-4,4′-oxydianiline and aromatic dicarboxylic acids. These polyamides were amorphous with good solubility in many organic solvents, such as NMP and DMAc, and could be solution-cast into strong and flexible polymer films. Their decomposition temperatures (Td) at a 10% weight-loss in nitrogen and air were recorded at 556-568°C and 537-555°C, respectively. The glass-transition temperatures (Tg) of all the polyamides were observed in the range of 218-253°C by DSC. Cyclic voltammograms of the polyamide films cast onto an indium-tin oxide (ITO)-coated glass substrate exhibited two reversible oxidation redox couples at 0.80-0.82 V and 0.96-0.98 V versus Ag/AgCl in an electrolyte containing acetonitrile solution. The polyamide films showed excellent electrochemical and electrochromic stability, with a color change from a colorless or pale yellowish neutral form to green and purple oxidized forms at applied potentials ranging from 0 to 1.2 V. These polymers can also be used to fabricate electrochromic devices, and they showed high coloration efficiency, high redox stability, and fast response time.

STILBENE DERIVATIVE, METHOD FOR PRODUCING THE SAME, AND ELECTROPHOTOGRAPHIC PHOTORECEPTOR

PROBLEM TO BE SOLVED: To provide a stilbene derivative having bulky groups in the molecule and having specified drum sensitivity characteristics, to provide a method for producing the same, and to provide an electrophotographic photoreceptor containing the same. SOLUTION: The stilbene derivative is represented by formula (1) (wherein the two R1 groups, which are independent of each other, are 6 to 20C substituted or unsubstituted alkyl groups, 6 to 20C substituted or unsubstituted alkoxyl groups, 15 to 20C substituted or unsubstituted aryl groups, or substituted or unsubstituted amino groups). The method for producing the same and the electrophotographic photoreceptor are also provided. The method comprises reacting a specified formylated triphenylamine derivative with a specified diphosphoric acid ester derivative in the presence of a base.
