Abstract

A number of new fluorescence compounds suitable as efficient laser dyes for the red spectral region have been synthesized and investigated. The new dyes are distinguished by good solubility in common organic solvents and high photostability. The laser effect of the dyes has been studied by the second harmonic of YAG:Nd³⁺ laser ((lambda) equals 532 nm) as a pump source. Some of the prepared DCM derivatives and pyridine analogues are efficient laser dyes. Two compounds from a new class of phenalemines possessing good photostability and excellent laser characteristics for the 600-690 nm spectral region are reported for the first time.
