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.

5,15-内消旋双(2-氯噻吩-3-基)卟啉的合成作为进一步功能材料的组成部分

进行 Suzuki-Miyaura 偶联反应以合成 5,15-中观-双（2-氯噻吩-3-基）卟啉，以获得进一步功能性卟啉的结构单元。研究了光物理和电化学性质，以了解 2-氯取代噻吩的作用，它们在 3 位连接到中观-卟啉的位置。证明了使用平衡法的计算计算来估计相对分子间相互作用以比较溶解度。安装在噻吩-3-基2位的氯原子减少了分子间相互作用，导致溶解度增加。
