Photoelectric conversion of a novel photoresponsive dendritic dye in LB monolayer ®lms

A novel D-p-A-s-A0 dendritic dye (D3) was synthesized. The dye molecule was successfully transferred onto an ITO electrode by the Langmuir±Blodgett (LB) technique and its photoelectric conversion property in LB monolayer ®lms was investigated. The results show that this dye exhibits good photocurrent generation that is dependent on the deposited pressure. Its photocurrent generation quantum yield at 25 mN mÿ1 is 0.32%, while that at 6 mN mÿ1 is 0.21%. # 2001 Elsevier Science B.V. All rights reserved.
