C-Br/N-H bulk polycondensation is firstly proposed and corresponding poly(3,4-dinitm-thiophen-2-yl aryl-amine)s derivatives have been successfully obtained with quantitative yield. Typical crystal analysis reveals that its effective reaction points distance (RPD, distance between Br and H atom) is 5.083 angstrom, which is 66.7% longer than the sum of van der Waals radius (r(w)) of bromine and hydrogen atoms (3.05 angstrom). Carbazole-based monomer was explored as a thermalsensor with excellent relative sensitivity (S-a) of 0.45% K-1.
