Abstract

Stark absorption spectroscopy is applied to 6-hydroxyquninoline (6-HQ) doped in polymer films of poly (methyl methacrylate) and poly (vinyl alcohol) at a temperature rang of 50-300 Kelvin. The results reveal that the molecular motion of 6-HQ in a polymer is very sensitive to the microenvironment of the surrounding matrix.

4. Proton-transfer tautomerism in 10-hydroxybenzo [h] quinolines: Heavy atom effects and non-hydrogen-bonded photorotamer formation in 77 K glassy matrixes

Abstract

The low-lying triplet states of 10-hydroxybenzo [h] quinolines and its halogenated derivatives 7,9-diiodo-10-hydroxybenzo [h]- quinoline (DIHBQ) in an excited-state intramolecular proton-transfer (ESIPT) process are investigated. Results show that in addition to the protic-solvent perturbation photoinduced breakage of the intramolecular hydrogen bond in 3-hydroxyflavones played a role in the prohibition of ESIPT reaction in 77 K methylcyclohexane glassy matrixes.
