Abstract

5, 11-and 5, 12-Bis (diisopropylsilyl) naphthacenes (2a and 2b) were synthesized, and their electronic properties were studied. In UV–visible spectra, the lowest energy absorption bands of 2a and 2b are more intense than that of naphthacene. Compounds 2a and 2b show intense yellow-green fluorescence, and the fluorescence quantum yields are almost two times higher than that of naphthacene.
