Abstract
Abstract Three kinds of 1,3-di(oligothienyl)propanes were synthesized. Two of them are homogeneous dimers composed of bithienyls or terthienyls and the third, a heterogeneous dimer in which bithienyl and terthienyl units are linked. It has been found that in the homogeneous dimers there is little electronic interaction between two oligothienyl units both in the ground and the singlet excited states. On the other hand, it has become clear that in the heterogeneous dimer an effective energy transfer from the bithienyl to the terthienyl unit takes place.
