A multifunctional luminescent network film electrochemically deposited from a new AIEE emitter for OLEDs and explosive detection

Abstract Electrochemical polymerization (EP) has attracted considerable attention because of its high material utilization, simple process and low cost. In this work, a new AIEE-active blue-emitting molecule, TCzDPAn, was synthesized. The multifunctional luminescent network film, with TCzDPAn as the building block, was conveniently prepared by EP. The EP film exhibits smooth surface morphology and high thermal stability, which shows great potential as light-emitting materials. In addition, the EP film shows very sensitive detection for 2,4,6-trinitrophenol (TNP) in solution and vapor states, through the synergetic effect of photo-induced electron transfer(PET) and fluorescence resonance energy transfer (FRET). Overall, the study indicates the potential of the multifunctional EP film as OLEDs materials and fluorescent sensors, which is attributed to the specific molecular features of TCzDPAn and the intrinsic properties of the EP film.
