Novel rapid switching and bleaching electrochromic polyimides containing triarylamine with 2-phenyl-2-isopropyl groups
A series of novel organosoluble polyimides and copolyimides with a propeller-shaped triarylamine unit were prepared from diamine and various aromatic dianhydrides via direct polycondensation. All of the polymers possessed tough, flexible, and strong films
Nitro compound, amine compound and polyamide derived therefrom
A polyamide represented by formula (6) is provided. The polyamide is fabricated by performing a polycondensation reaction with amine compound shown in formula (4) and an acid or derivative thereof shown in formula (5) as monomers. In formulas (5) and (6),

Experimental and theoretical investigation of a new rapid switching near-infrared electrochromic conjugated polymer
A new rapid switching near-IR electrochromic conjugated propeller-shape polymer (PBTPAFL) with lower oxidation potential containing a di-triarylamine group was synthesized via Suzuki coupling approach. The observed UV-vis-NIR absorption changes in the PBT
