四种源自二苯乙烯氮唑骨架的染料（2-DASPI、4-DASPI、LDS 698和LDS 722）已嵌入光学透明的氟钠云母层中。X射线衍射数据表明，DASPI染料的长轴平行于层排列，在很大程度上保持了它们的溶液相结构。另一方面，LS染料的构象似乎是显着扭曲，由于二维限制。DASPI和LDS染料在云母中的荧光寿命的巨大差异是由发色团分子结构描述的。
Four dyes (2-DASPI, 4-DASPI, LDS698, and LDS722) derived from the stilbazolium skeleton have been intercalated into optically transparent Na-fluorine mica layers. X-ray diffraction data show that the long axis of DASPI dyes is aligned parallel to the layer, largely maintaining their solution phase structure. On the other hand, conformation of LS dyes appears to be significantly distorted, due to the two-dimensional confinement. A huge difference in the fluorescence lifetimes between DASPI and LDS dyes in mica was described by the chromophore molecular structures.
