In this paper, p-hydroxylphenyl meso-substituted porphyrin arrays were synthesized by the equivalent mixture of two aldehydes using the one-step method. The analysis of TLC showed that the prod-uct includes six compound. The compounds were separated by column chromatography on the aluminum oxide with different ratios of chloroform/ethanol eluted. The six compounds were confirmed by spectroscopic analysis, and their fluorescence spectra were studied. The results showed that the fluorescence intensity was very weak at 440 nm and enhanced with the hydroxyl increased, and was strong at 650 nm and weakened with the hydroxyl increased for p-hydroxylphenylporphyrin arrays.
