The encapsulation of a hemicyanine dye, LDS 730, into the 1D nanochannels of MgAPO-5 aluminophosphate by "one-pot" synthesis, based on "in situ" occlusion via a crystallization inclusion method, has led to a hybrid material with emission in the NIR region. The tight fitting between the molecular size of the guest dye and the pore dimensions of the host has enabled a rigid conformation of the LDS 730 dye within the nanochannels. Consequently, fluorescence in the NIR range of the spectra is enhanced with respect to the dye in solution. The synthesis of the hybrid material was optimized through a systematic variation of the gel composition via MW in order to obtain a pure phase.
通过“一锅法”基于“原位”封闭的结晶包容法，将半花菁染料 LDS 730 封装到一维纳米通道的 MgAPO-5 沸石中，合成了一种在近红外区域发射的杂化材料。客体染料的分子尺寸与主体孔尺寸之间的紧密配合使得 LDS 730 染料在纳米通道内具有刚性构象。因此，与溶液中的染料相比，光谱的近红外区域的荧光得到增强。通过系统地改变凝胶组成（通过 MW）优化了杂化材料的合成，以获得纯相。
