E/Z isomerization effects on aggregation-enhanced emission of tetraphenylethene derivatives assisted by host-guest recognition

Abstract

Pure stereoisomers of tetraphenylethene derivatives functionalized with dibenzylamine groups, E and Z conformers, were successfully synthesized. Their aggregation-enhanced emissions, which occurred through host-guest recognition with a dibenzo-24-crown-8 based tetraphenylethene under an acid condition, showed recognizable isomerization effects.
