Abstract

Abstract: It was found that exciplex can be formed between singlet excited state of 9-vinyl anthracene and p-N, N-dimethylamino styrene in various solvents. Exciplex emission Wavelength red shifts and fluorescence quantum yield Φ_e of exciplex decrease with the increase of the polarity of solvents. The relative yield of photodimerization reduces with Φ_e. Exciplex intermediate mechanism was suggested for the photodimerization between 9-vinyl anthracene and p-N, N-dimethylamino styrene.

Key words: exciplex, 9-vinyl anthracene, p-N,N-dimethylamino styrene
