Abstract

Abstract Triplet state and photoinduced charge separation dynamics under adsorption was Confirmed for the first time for the polymer without or with coadsorbed electron acceptor, respectively. The absorption spectrum of the triplet polymer is similar to the Tn← T1 band of N‐ethylcarbazole, showing no appreciable interchromophoric interaction. Absorption spectra of the coadsorbed systems comprise the polymer cation and electron acceptor anion. The ion radicals on the cellulose substrate undergo mutual recombination, and simple uni‐ and bimolecular decay kinetics do not hold. This mechanism was compared with that for poly(N‐vinylcarbazole) film.
