Synthesis of 5,15-meso-bis(2-chlorothiophen-3-yl)porphyrin as a building block for further functional materials

A Suzuki–Miyaura coupling reaction was performed to synthesize 5,15- meso -bis(2-chlorothiophen-3-yl)porphyrins in order to obtain a building block for further functional porphyrins. Photophysical and electrochemical properties were investigated to understand the effect of 2-chloro substituted thiophenes which are connected at their 3-position to the meso -position of the porphyrin. A computational calculation with counterpoise method was demonstrated to estimate the relative intermolecular interaction in order to compare solubility. Installed chloro atoms at the 2-position of thiophen-3-yl decreased in intermolecular interaction which caused an increase in solubility.
