Abstract
The features of organic thin films are in the versatility of the molecular structures and the molecular aggregation states. A specialproject research on organic thin films for information conversion, which is supported by the Grant-in-Aid from the Ministry of Education, aims at the most efficient information conversion of the aggregated molecules in organized molecular environments. In this paper, the responses of the organic thin films to electrical and/or optical excitations are discussed in terms of the molecular structure and molecular alignments in thin films. Some problems to be solved are also pointed out.
