1,2-Bis(2-methyl-1-benzothiophen-3-yl)perfluorocyclopentene derivatives having 2,4-diphenylphenyl substituents at 6 and 6′ positions of the benzothiophene rings were synthesized. Both mono- and di-substituted derivatives, compounds 1a and 2a, formed amorphous states at room temperature and their glass transition temperatures were observed at 88 °C and 127 °C, respectively. Remarkable spectral shift of the fluorescence from 650 nm to 450 nm was observed for the amorphous film of closed-ring isomer 2b upon visible (λ > 450 nm) light irradiation.
