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.

通过在沸石MgAPO-5纳米通道内紧密封闭半菁染料来增强NIR发射†

通过“一锅法”合成将半花青染料LDS 730封装到MgAPO-5铝磷酸盐的1D纳米通道中，这种方法基于通过结晶包含方法进行的“原位”阻塞，导致了杂化材料在近红外区域。客体染料的分子大小与主体的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，相对于溶液中的染料，在光谱的NIR范围内的荧光增强。通过经由MW的凝胶组成的系统变化来优化杂化材料的合成以获得纯相。
