摘　　要：3-溴咔唑在水中可以形成均匀稳定的胶态微晶体分散体系,能够诱导完全不同于单体的磷光发射信号,波长大幅红移到470nm～700nm之间.估计为3-溴咔唑聚集体或晶体缺陷的发射.而且溶液相当稳定,放置较长时间不会产生沉淀,并且磷光信号有很好的重现性,发光体浓度与发光强度具有良好的线性关系.文章对3-溴咔唑胶态晶体奇特的磷光特性进行了初步讨论.3-Bromocarbazole could form stable colloidal-microcrystal suspension in water and the system could produce novel phosphorescence emission band between 470 nm～700 nm,which was obviously different from the monomer phosphorescence of 3-Bromocarbazole.It was estimated that the red-shifted largely emission band derived from the 3-Bromocarbazole aggregates or defects in crystals.Furthermore,the suspension was characterized by the quite stability and no precipitates formed during standing for a long time,the improved greatly reproducibility of the phosphorescence signal,and good linearity of the plots of 3-Bromocarbazole concentration vs.RTP intensity.
