The photophysical properties (photostability, spectral-luminescent and generation properties) of eight new organic compounds have been studied, in which the molecular composition of two flurophores -- 1,3,5-triphenylpyrazoline and 2,5-diphenylzoxazole-1,3 (or 2,5- diphenyloxazole-1,3,4) -- were included. The effect of the structure of the investigated molecules and the polar properties of solvents on the spectral position of absorption and fluorescence bands was analyzed. The dyes have been found to have a fluorescence quantum efficiency (gamma) between 0.40 and 0.82 in these solvents. The dye laser performance using these dyes has also been investigated using the same solvents under nitrogen-laser pumping to compare them with the commercially available standard dye POPOP, which generates radiation in the violet spectrum region and allows the extension of the range of the active media used in liquid lasers in this spectrum region. A tuning range of nearly 60 nm was obtained in the blue region with efficiency up to 85% in comparison to the standard dye POPOP.
