The absorption and fluorescence of acridine, phenazine, their cations, and phenazine-di-N-oxide were studied in polymer matrices. The correspondence to spectra in liquid or frozen solutions is established for the polymer matrices. The effect of the matrix and compression 0-27 kbar on the spectral properties are compared. The extent of solid solvent perturbation on spectral location and bandwidth is illustrated for acridine and phenazine. The red shifts of the absorption and fluorescence band maxima are compared for two polymer matrices. The magnitude of the pressure response of the fluorescence bands and intensities differs for degassed and nondegassed plastic solutions. Author
