Abstract

A kind of new metalloporphyrin complex of the present invention, its structural formula is as follows: also provide the preparation method of above-mentioned metalloporphyrin complex, 5,10,15,20-tetrakis (4-hydroxyphenyl) metalloporphyrin The morphine complex is dissolved in tetrahydrofuran, 3-isocyanatopropyltriethoxysilane is added, reflux reaction is carried out under the catalysis of triethylamine, and then hydrochloric acid solution is added to obtain the above-mentioned metalloporphyrin complex. Also provided is a preparation method of a porphyrin composite photoelectric thin film, adding hydrochloric acid solution to the tetrahydrofuran solution of the above-mentioned metalloporphyrin complex compound for reaction, and coating the obtained solution on a substrate to obtain a porphyrin composite photoelectric thin film . The invention realizes carrier transmission between multilayer self-assembled organic thin film layers, thereby improving the photoelectric response of the organic thin film.

Description

Technical field [0001] The field of organic photoelectric materials of the present invention relates to a metal porphyrin complex, in particular to a new metal porphyrin complex and a preparation method and application thereof. Background technique [0002] Organic photoelectric materials have great application prospects in photovoltaic solar cells, OLEDs, organic field effect transistors, biosensors and other fields, and have become a hot spot in the field of new materials. Compared with inorganic optoelectronic materials, organic optoelectronic materials have significant advantages, such as low density, low price, and easy processing, but they also have some disadvantages. For example, in the field of organic photovoltaic cells, the photoelectric conversion efficiency is low. In the field of optoelectronic materials, whether in the field of photovoltaic cells or OLED, optoelectronic materials are prepared in the form of multi-layer films. However, in the traditional multilaye...
