The facile condensation of bis(triphenylethylene)-functionalized -phenylenediamine with -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.
双(三苯乙烯)官能化的对苯二胺与醌的简便缩合反应能高产率地生成基于吩嗪的发光剂。荧光研究表明,四种新的吩嗪衍生物在水含量≥60%的四氢呋喃溶液中均表现出聚集诱导发光(AIE)行为。通过动态光散射、共聚焦显微镜和扫描电子显微镜进一步研究了聚集体的尺寸和结构,结果均表明,随着水含量百分比的增加,大致呈球形的颗粒尺寸减小。
