Modular Synthesis of Phenazine-Based Aggregation-Induced Emission Materials
Abstract:
The facile condensation of bis(triphenylethylene)-functionalized ortho-phenylenediamine with ortho-quinones gives phenazine-based luminogens in high yield. Fluorescence studies demonstrate that each of the four new phenazine derivatives displays aggregation-induced emission (AIE) behavior in THF solutions containing ≥60% water. The sizes and structures of aggregates have been investigated further by dynamic light scattering, confocal microscopy, and scanning electron microscopy, each showing a decrease in the size of roughly spherical particles with increasing percentage of water.
