摘要/Abstract

摘要：

甲醛为公认的致癌物质，本文针对目前甲醛分析需使用专用仪器和试剂盒的不便现状，合成了分子探针（km2bn），通过晶体结构分析发现其苯并二氮杂卓基团与水自组装为一维分子线材料（km2bn·H₂O），可与甲醛分子发生固-气相Hantzsch反应，生成具有更大共轭体系二氢吡啶杂环结构，双官能团反应使其生成一维伸展的线性聚合物，共轭体系得到更大的拓展，具有深色与光谱红移效应，其颜色坐标与甲醛浓度具有线性关系，兼具检测选择性，因而可通过该可视显色反应检测甲醛，并可制成试纸，方便普通家庭使用。

Abstract:

Theformaldehyde had been identified as a carcinogenic and teratogenic molecule. To solve the problems of inconvenient analysis techniques, a novel probe of (km2bn) basedon the structure of benzodiazepin was prepared, which could be assembled to a 1D molecular line (km2bn·H₂O) by water. This supramolecular material could react with theformaldehyde and yield a colored polymer through Hantzsch reaction. The formaldehyde sensing film was prepared using the sol-gel method. The chemochromicdata were collected by the CCD and then processed by thecomputer and found thelinear correlation with the concentrations of formaldehyde.

Key words: benzodiazepin, molecular probe, molecular line, formaldehyde, color coordinate
