Problems solved by technology

The research on porphyrin is currently mainly aimed at modifying tetraphenylporphyrin, but the general solubility is not good, and more by-products are easily generated during the modification process, which is difficult to separate and purify.
Molecular links are mainly realized through amide bonds, acid anhydride bonds and adipic acid, which have a relatively large impact on the planarity of molecules, and are not conducive to electron transfer, thus affecting its photoelectric effect.

Description

technical field [0001] The invention relates to a metalloporphyrin series compound with triptycene as a skeleton bridged by pyrenetetraketone and a preparation method thereof, belonging to the field of photoelectric conversion materials. Background technique [0002] Triptycene and its derivatives are a class of bridged ring compounds with a three-dimensional rigid structure. The highly anisotropic materials synthesized from the unique three-dimensional structure of triptycene and a series of conjugated derivatives have excellent photoelectric properties. In recent years, triptycene has shown attractive applications in many fields due to its unique structural characteristics and rich reactivity. Porphyrin compounds themselves have excellent photoelectric properties and thermal stability, and have strong characteristic electronic absorption spectra in the visible light region. The design and synthesis of optoelectronic functional materials and devices based on porphyrin comp...
