OXYGEN SENSORS BASED ON HARD-SOFT ACID-BASE RELATIONSHIPS

摘要

A fluorescence quenching oxygen sensor (100) comprises a support (102) having coated thereon; a compound having hard or soft acid groups (104); and one or more pyrene compounds (106) represented by Y-R-Pyrene(I) attached to the compound having hard or soft basic groups; wherein Y is a hard or soft basic group and R is an aliphatic linking group having 1 to 19 carbon atoms. The sensor can be used to prepare a fluorescence quenching oxygen detector.
