Synthesis of Laser Dyes
Abstract
This report describes the progress made in attempts to prepare seven laser dyes. These dyes all have a 2-(4-pyridyl-1,3-oxazole structure one dye. The synthesis of one dye 2-N-methyl-4-pyridinium) phenanthro 9,10-D-1,3-oxazole tosylate (I) has been completed. Preliminary testing has shown this dye to have a quantum fluorescence yield of 0.99. It absorbs at 410 nm and fluoresces at 534 nm in ethanol. Determination of the lifetime and output under optimum conditions is yet to be done. Work is continuing on the preparation of derivatives of I with methoxy groups on the phenanthrene ring. Three aminoketone hydrochlorides derived from 1-indanones have been prepared. These are 2-amino-1-indanone, 3,3-dimethyl-2-amino-1-indanone and 5-methoxy-3,3-dimethyl-2-amino-1-indanone. Attempts are being made to convert these into the corresponding 2-(4-pyridyl)-1, 3-oxazoles.
