Synthesis of four N-[4-(diarylpyrazolinyl)phenyl]maleimides and their fluorescence properties are described. Among these, the N-[4-(3,5-diphenyl-2-pyrazolin-1-yl)phenyl]maleimide shows a ten-fold fluorescence enhancement upon thiol addition and forms a fl

1-Phenyl-3,5-diaryl-2-pyrazolines are nitrated, sulfurated, and acylated in the para-position of the 1-phenyl ring.In the presence of POCl3, pyrazolines form triphenylmethane dyes with a Michler's ketone.
