✦ Synopsis

The stabilization of the ground-state keto tautomer of 'I-hydroxyquinoline ( 7HQ) has been observed in methanol/argon mixed matrices at 10 K. The stabilized tautomer has been ascribed to the isolated 7HQ-(MeOH), bridged complex based on the observation that the open-chain methanol dimer concentration reaches a maximum concomitantly with the fluorescence excitation spectrum of the keto tautomer centered at 420 nm. Also discussed are the excited-state proton-transfer processes for the 7HQmethanol unbridged complexes.
