Research on the Latent Fingerprint Imaging of an Imide Compound Containing a Phenothiazine Group
The phenothiazine group had not only a non-coplanar bowl-like structure,but also an excellent fluorescent unit.To study the aggregation-induced emission performance of compound containing phenothiazine group and its application in the field of the latent fingerprints imaging,a novel phenothiazine-based imide compound was synthesized using phenothiazine as raw material,through nucleophilic substitution,reduction and imidization reaction,and its optical property was measured.The result illustrated that the synthesized compound exhibited aggregation-induced emission property in tetrahydrofuran/water mixture,and it could be used as a developer to image latent fingerprint on a glass slides.The developer could identify partial first-level,second-level,and third-level features of the latent fingerprint.
