摘要
Methoxy groups is favorable for film-forming property of oligophenylenevinylenes （OPVs） and the Langmuir-Blodgett film of 1,4-bis （3,4,5-trimetlaoxystyryl）-2,5-dimethoxybenzene （MOPV） was prepared. It might be the formation of H-aggregate of MOPV in the LB film that results in a 57 nm blue shift of λmax for the absorption and a 58 nm red shift of λmax for the fluorescence, respectively.
