Abstract
Recently the photoinduced infrared spectrum of neutral polyfuran was r ecorded. The observed spectrum combined with the doping-induced infrar ed and the FT-Raman spectrum of the neutral polymer, interpreted in te rms of the effective conjugation coordinate theory, suggests that the samples consist of a bimodal distribution of conjugation lengths. PFu seems to be very stable in air at room T and shows the largest pi elec tron delocalization among polyheteroaromatics.
