Enhancement of NIR emission by a tight confinement of a hemicyanine dye within zeolitic MgAPO-5 nanochannels

Author affiliations

Abstract

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.
