Well conducted: a two-dimensional porphyrin covalent organic framework is described. Owing to the eclipsed stacking alignment, the framework is conductive and allows high-rate carrier transport through the porphyrin columns. The central metal in the porphyrin rings changes the conducting nature of the material from hole to electron, and to ambipolar conduction. It also drives the high on-off ratio photoconductivity of the framework.
制备了一种二维卟啉共价有机框架。由于堆积方式为交错式，该框架具有导电性，可允许通过卟啉柱进行高速载流子输运。卟啉环中的中心金属改变了材料的导电机理，使其从空穴型变为电子型，再变为双极型。这也使得该框架具有高光响应比光电导性能。
