Preparation of π-conjugated polymers consisting of 1-aminopyrrole and 4-amino-1,2,4-triazole units

π-Conjugated polymers based on 1-aminopyrrole and 4-amino-1,2,4-triazole were prepared. Pd-catalyzed organometallic polycondensation gave poly(arylene-ethynylene) (PAE)-type π-conjugated polymers consisting of BOC-protected 4-amino-1,2,4-triazole (Taz(BOC)) units (BOC= t-butoxycarbonyl). The number average molecular weights (Mn) were determined to be 5200-19,200 using GPC. An alternating copolymer of Taz(BOC) and bithiophene (Th-Th) units, P(Taz(BOC)-Th-Th)n-Pd, with an Mn of 10,800 was also prepared by Pd-catalyzed organometallic polycondensation. (Taz(BOC)-Th-Th)n-Pd showed a UV-Vis absorption peak at λmax = 425 nm, which is reasonable for a re-conjugated five-membered ring polymer with a coplanar structure. The deprotection of the BOC group of the polymers proceeded at 200 °C; this BOC-deprotection was investigated using a model compound. The optical and electrochemical properties of the re-conjugated polymers are reported.

A facile and solvent-free synthesis of 3,5 -disubstituted-4-amino-1,2,4-triazoles by reactions of aromatic nitriles with hydrazine

A variety of 3, 5-disubstituted-4-amino-1,2,4-triazoles were prepared by reactions of aromatic nitriles with hydrazine monohydrate. The structure of 3,5-diphenyl-4-amino-1,2,4-triazole was established by an X-ray analysis.
