摘要：

A series of 3-aryl-4-hydroxycyclobut-3-ene-1,2-diones were synthesized and examined as sensitizers for a TiO2 solar cell. The compounds showed strong affinity for TiO2 and the fluorescence intensity and self-assembly of the 3-aryl-4hydroxvcyclobut-3-ene-1,2-diones on the TiO2 surface were important factors in enhancing the solar-light-to-electricity conversion efficiency. The highest efficiency of 0.96% was observed for 3-[4-(didodecylamino)phenyl]-4-hydroxycyclobut-3-ene-1,2-dione. (C) 2003 Elsevier Ltd. All rights reserved.
