A series of conjugated polyyne porphyrins, in which two porphyrin macrocycles are connected with both ends of diarylpolyyne through aromatic ring, has been prepared and their spectroscopic behaviors were investigated. Diarylpolyyne consisting of aryl group and conjugated triple bond system have rigid and linear structure, and the two porphyrins are held at a fixed geometry and a determined distance. In their absorption spectra, porphyrin Soret bands were red- or blue-shifted depending on their edge-to-edge or face-to-face orientation.
一系列共轭的聚炔卟啉被制备,其中两个卟啉大环通过芳香环连接在二芳聚炔的两端,并对它们的光谱特性进行了研究。包含芳基和共轭三键系统的二芳聚炔具有刚性和线性结构,两个卟啉被固定在确定的几何形状和距离上。在它们的吸收光谱中,卟啉的索雷特带根据它们的边对边或面对面取向表现出红移或蓝移。
