Abstract
In this paper, we report on the results of spectrofluorimetric study of new fluorescent sensor based on [Zn2L2] doped in ethyl cellulose. The sensor optical signal is based on the rapid fluorescence quenching in the presence of ethanol vapor. The ethanol vapor detection limit in a gas mixture by means of sensor based on [Zn2L2] doped in ethyl cellulose is 0.56 ppt. Being highly sensitive and selective to the ethanol vapor presence, instant in response and easy to use, the sensor may find an application for the monitoring of the content of ethanol vapor in the air at industrial and laboratory facilities. This sensor can serve as the basis of pocket gas analyzers for detecting ethanol in the exhaled air.
