Porphyrinyl quinoxaline organic photovoltaic material as well as preparation method and application thereof

The invention belongs to the field of organic small molecule photovoltaic materials, and discloses a porphyrinyl quinoxaline organic photovoltaic material and a preparation method and application thereof. The chemical structure of the porphyrinyl quinoxaline photovoltaic material is shown as a formula (I), a porphyrin ring is used as a central power supply unit, two cheap quinoxaline power absorption units are connected to two symmetrical meso sites of porphyrin to synthesize a target molecule, a push-pull electron effect is formed, and intramolecular charge transfer and broadening absorption can be effectively enhanced. By changing the side group of quinoxaline, the absorption and energy level of molecules are effectively adjusted, and the purpose of further optimizing the material performance is achieved. The invention proves the possibility of taking quinoxaline with simple synthesis conditions as a porphyrin electron withdrawing unit, and provides a new direction for molecular design of porphyrinyl quinox
