英文摘要： Considering the fact that the structure of low molecular-mass organic gelators(LMOGs) can be cut and the sensing performance of semiconductor nanoparticles depend on its microstructure, firstly, a series of LMOGs can be designed and synthesized, taking the supramolecular organogel film of the LMOGs as template and artificial models of "biomineralization"process, a variety of light-emitting semiconductor micro-nano-materials can be prepared by transcription method, and ultimately the composite films can be applied to the sensing detection of amines. The project will focused on the effect of the LMOGs structure, the organic gel three-dimensional network density, film thickness and semiconductor nanoparticles micro-structure on the sensing performance of the composite film, summarizing its regularity, finally, the sensing mechanism can been proposed using a variety of photophysical techniques, and the general assembly theory of the highly sensitive film can been proposed. It is believed that the scientific research of the sensing performance of semiconductor nanoparticles stabled by the supramolecular organic gel will help establish design ideas of the composite sensing film materials, exploring the new field of sensing film materials. At the same time, the study of the project will certainly enrich gel materials c
