文摘

A series of halogenated in the para-position DBMBF2 derivatives were synthesized. The absorption and fluorescence of the Hal-DBMBF2 derivatives are measured. The fluorescence QY of the Hal-DBMBF2 (except I-DBMBF2) is larger than of DBMBF2. All Hal-DBMBF2 are able to form fluorescent exciplexes with benzene and toluene.
