Synthesis of the Vinyl Derivatives with Aggregation Induced Emission Effect and Their Application to the Detection of DNT

doi:10.7517/j.issn.1674-0475.2012.03.182

Abstract

Abstract: Two vinyl derivatives with AIE properties were synthesized by Wittig-Horner reaction. The UV and fluorescence spectroscopy shows that the two compounds have weak π-π interactions in the aggregation state. Both of them showed strong enhancement fluorescence luminescence properties in the aggregation state. The distortion of their molecular configuration made the diffusion of DNT vapor molecules to the film easier, so the films have shown higher fluorescence quenching efficiency to DNT, and their fluorescence quenching toward DNT is reversible.

Key words: nitroaromatic, aggregation induced emission, triphenylamine, fluorescence quenching
