The Uses of 6-Hydroxyquinoline
6-Hydroxyquinoline was used in synthesis of 2,6-substituted-benzo[d]thiazole analogs and 2,4-substituted-benzo[d]thiazole analogs.
Definition
ChEBI: A monohydroxyquinoline that is quinoline substituted by a hydroxy group at position 6.
General Description
6-Hydroxyquinoline is an ideal photoacid system for exploring excited-state proton transfer (ESPT) reactions. The excited-state proton transfer and geminate recombination of 6-hydroxyquinoline encaged in catalytic Na+-exchanged faujasite zeolites X and Y have been explored by measuring steady-state and picosecond time-resolved spectra.
