Fluorescence Emission Enhancement with Metal Salts in the Solid-state via Dipole-ion Interactions

Abstract

Many fluorescent molecules based on triarylamine backbone have been synthesized and explored their potential applications for sensing and solid-state fluorescence properties. The electrondonating ability of the core triarylamine backbone and the suitable electron-accepting nature of the terminal functional groups make them an excellent donor-acceptor system in realizing fluorescence emission. Here, we reported a ptoulenesulfonyl hydrazide derivative of tri(biphenyl-4-yl)amine (TBA-THZ) for sensing and solid-state fluorescence enhancement properties. The TBA-THZ was well characterized by various spectroscopic techniques such as 1H-NMR, 13CNMR, HR-MS, FT-IR, SEM and PXRD
