摘要
We report photoinduced absorption measurements in the millisecond time domain of poly[ 1,6-di(N-carbazolyl)-2,4-hexadiyne] (poly-DCHD) obtained by pumping on the side group. We show that the photoexcited states are similar to those detected by pumping on the absorption band of the conjugated backbone. This fact can be explained in terms of fast migration of the excitation energy from the side group to the conjugated chain. (C) 1998 Elsevier Science S.A. All rights reserved.
