Document Type and Number:
WIPO Patent Application WO/2021/000467
Kind Code:
A1
Abstract:
Disclosed are a fluorescent compound for the detection of isocyanate substances, a preparation method therefor and the use thereof as a test-paper-type detection probe. The fluorescent compound is 2,4-di(((4'-(diphenylamino)-[1,1'-biphenyl]-4-yl)imino)methyl)phenol. The fluorescent compound is prepared by means of a one-step method. The preparation thereof is simple and convenient, and the yield thereof is higher, and same can respond quickly and specifically to isocyanate substances. The fluorescence intensity of the fluorescent compound increases as the isocyanate concentration increases. The fluorescent compound can be made into a portable test-paper-type probe for the detection of isocyanate substances in air, and can achieve the visual detection of volatile isocyanate gases. The probe has an aggregation-induced light emission effect, resulting in it being possible for there to be a higher fluorescence quantum yield when using a test-paper-type probe for detection. A fluorescence probe prepared by the present invention can be used for the detection of isocyanate substances in a solution and of gaseous isocyanate substances, and can be used to detect isocyanate in atmospheric air, water resources, etc.
