Regioisomeric monopyridine-functionalized triarylethene: small AIEgens with isomeric effect and an efficient platform for the selective and sensitive detection of Pd2+ and Fe3+
Regioisomeric monopyridine functionalized triarylethenes are established as small AIEgens. These compounds are utilized to detect Fe+3 and Pd+2 selectively in nM range. The detection is further extended for the on-site applications.
