Novel Polyamides with 5H-Dibenzo[b,f]azepin-5-yl-Substituted Triphenylamine: Synthesis and Visible-NIR Electrochromic Properties
In this study, a new diamine monomer, namely 4,4′-diamino-4”-(5H-dibenzo[b,f ]azepin5-yl)triphenylamine, was prepared and polymerized with four kinds of dicarboxylic acids via direct polycondensation reaction resulting in a novel series of soluble and electroactive polyamides (PAs). The tough thin films of all PAs could be solution-cast onto an indium-tin oxide (ITO)-coated glass substrate owin...
متن کاملSynthesis and Electrochromism of Highly Organosoluble Polyamides and Polyimides with Bulky Trityl-Substituted Triphenylamine Units
Two series of polyamides and polyimides containing bulky trityl-substituted triphenylamine units were synthesized from condensation reactions of 4,4′-diamino-4′ ′-trityltriphenylamine with various dicarboxylic acids and tetracarboxylic dianhydrides, respectively. The polymers showed good solubility and film-forming ability. Flexible or robust films could be readily obtained via solution-casting...
متن کاملHigh Contrast Ratio and Rapid Switching Electrochromic Polymeric Films Based on 4-(Dimethylamino)triphenylamine-Functionalized Aromatic Polyamides
A series of electroactive aromatic polyamides with 4-(dimethylamino)triphenylamine [(NMe2)TPA] units in the backbone were prepared from a newly synthesized diamine monomer, 4,4′-diamino-4′′-(dimethylamino)triphenylamine, and various aromatic dicarboxylic acids via the phophorylation polyamidation reaction. These polyamides are readily soluble in many organic solvents and can be solution-cast in...
متن کاملSynthesis and anticancer activity of novel 5-(indole-2-yl)-3-substituted 1,2,4-oxadiazoles.
A new series of 5-(indole-2-yl)-3-substituted 1,2,4-oxadiazoles were synthesized and evaluated for their anticancer activities. Structures of the compounds were confirmed by spectroscopic methods. Structural modifications were done to improve the antiproliferative activity of compound 1. The results indicated that a benzyloxyl substituent on the C-4 position was better than a methyl substituent...
متن کاملMultichromic Polymers Containing Alternating Bi(3-Methoxythiophene) and Triphenylamine Based Units with Para-Protective Substituents
Two novel triphenylamine-based thiophene derivative monomers, 4-cyano-4',4″-di(4-methoxythiophen-2-yl)triphenylamine and 4-methoxy-4',4″-di(4-methoxythiophen-2-yl)triphenylamine, were successfully synthesized. The corresponding polymers including poly (4-cyano-4',4″-di(4-methoxythiophen-2-yl)triphenylamine) and poly (4-methoxy-4',4″-di(4-methoxythiophen-2-yl)triphenylamine) were electrochemical...
