Outline of Final Research Achievements

A novel class of diad molecules that electron donating dyes covalently link with electron accepting dye components was designed and synthesized. The obtained diad molecules spontaneously stacked in response to external stimuli such as solvents and temperature and successfully gave highly ordered alignments of the individual component. Conventional organic photovoltaic devices using the self-assembled diad as photoactive layers exhibited photocurrent. Considering about the result, the diad assembly successfully provide p-n heterojunction which contributes charge separation followed by charge transportation in the device.
