Excited-state dynamical behavior of 1,4-anthraquinone in a fluid solution.
The excited triplet-state transient time profiles of 1,4-anthraquinone (1,4-AQ) have been measured in a degassed CCl4 fluid solution at different temperatures near room temperature, together with the steady-state emission spectra, which consist of the S1(n, pi*) and weak S2(pi, pi*) fluorescence at room temperature, and of the T1(pi, pi*) phosphorescence at 77 K. Quantitative analysis of the T1 triplet decay profiles measured as a function of temperature provides estimates for the energy and rates that characterize the excited-state dynamical behavior of 1,4-AQ.
