Abstract

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
