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.
