| Outline of Final Research Achievements |
"Precursor approach" provides a nonconventional means towards the achievement of irreversible change of solubility, color, fluorescence quantum yields, semiconductivity etc in solution, film and solid, by in-situ photoreaction or thermal reaction. We have prepared several pi-expanded aromatic compounds with this approach for the development of functional materials: 1) synthesis of pi-expanded aromatic compounds like pentacene dimer, which is difficult to be prepared by conventional means because of the instability of pentacene; 2) synthesis of heterocyclic pi-expanded molecules like push-pull indolizino[5,6-b]quinoxaline derivatives, tetracene-TTF, and benzotriphyrin(2.1.1) compounds; 3) synthesis of latent fluorescence materials, an optically and thermally switchable electronic structure based on an qnthracene--BODIPY conjugate and highly fluorescentpyrene-dyes from non-luminous precursors.
