Research on the Optical Properties and Latent Fingerprint Imaging of a Triphenylamine-Based Difluoroboron Compound
The difluoroboron compounds not only exhibit excellent photophysical properties,but also have wide applications in the field of optoelectronic functional materials.In order to further explore the application,a difluoroboron compound containing triphenylamine and phenothiazine groups was synthesized using phenothiazine as raw material orderly through nucleophilic substitution reaction,reduction reaction,nucleophilic condensation reaction,and coordination reaction.The measurement results in different polar organic solvents and tetrahydrofuran/water mixtures showed that it has intramolecular charge transition characteristics and aggregation-induced emission active,and the experimental results were explained by quantum chemical calculations.In addition,it can serve as a developer to image latent fingerprint on glass plates,as well as clearly identify partial first,second,and third fingerprint feature details of latent fingerprint.
