A series of 2-(4-styrylphenyl)-1,4,5-triaryl imidazole derivatives have been
efﬁciently synthesized through Wittig reactions starting with 2-[(4-bromomethyl)phenyl]-
1,4,5-triarylimidazoles and been veriﬁed by spectroscopic data. The optical absorption and
emission properties of the synthesized novel (E)-stilbene derivatives were examined in dilute
ethanol solution. Most of the products exhibit a strongly enhanced ﬂuorescence intensity.
