Abstract
The photochemical behavior at cryogenic temperatures of phenoxazine an d phenothiazine dyes in poly(vinyl alcohol) was investigated by using persistent spectral hole burning. The importance of hydrogen-bondings has been confirmed by measuring the effects of the addition of N,N,N', N'-tetramethyl-p-phenylenediamine on the holewidth and the hole area o f various cationic dyes at 20 K. The hydrogen bonds around the ring-N atom affect the total dephasing time, while the hydrogen bonds around the amino groups as the substituents and around the ring-N atom contro l the efficiency of hole formation.
