摘要：

Benzoheterodiazole-based fluorophores with aggregation-induced emission (AIE) properties are synthesized and their photophysical properties in different states (solution, film, and powder) are investigated. These compounds present excellent thermal stability, and the decomposition temperature is above 300 degrees C. Among these compounds, the fluorophores with triphenylamine (TPA) group present better fluorescent emissions in solutions as well as in aggregated states, and the highest solution fluorescent efficiency is up to 75.2% in solution. Meanwhile, the fluorescent compounds terminated with triphenylethene (TPE) exhibit the classical AIE properties. Furthermore, these compounds might be used as emissive layers for the fabrication of red, orange and green organic light emitting diodes.
