Abstract

Herein a new azobenzene-substituted porphyrin molecule was synthesized, characterized and its optoelectronic properties were investigated by combining the high optoelectronic properties of porphyrin with the photosensitive properties of azobenzene. The carboxylic acid of azobenzene was covalently connected to -OH group of the porphyrin ring by using Steglich esterification. Molecular structure of the obtained azobenzene-porphyrin (8), was elucidated, by FTIR, (1) H and (13) C NMR and HRMS. After structural characterization absorption and emission, characteristics were determined in solvents that have different. And also, optical and fluorescence behaviors in the range of different acid pH with trans-cis photoisomerization behaviors were investigated in aqueous-THF solution in acid media.
