Description
Technical Field
The invention belongs to the technical field of organic synthesis and the field of organic photoelectric functional materials, and relates to a tetraperylene diimide based phenyl tetraphenanthrene ring conjugated porphyrin derivative and a preparation method thereof.
Background
Porphyrin compounds have unique photoelectric properties, good light and thermal stability and larger molar absorption coefficient in a visible light range, so that the porphyrin compounds have wide attention and application in the fields of biochemistry, medicine and pharmacology, analytical chemistry, photocatalysis, material science and the like. In recent years, the research and development of designing and synthesizing photoelectric functional materials and photoelectric devices by using the unique electronic structure and photoelectric properties of porphyrin molecules have become very active research fields at home and abroad, for example, in the aspects of simulating photoinduced charges and energy transfer of biological photosynthesis centers, the porphyrin molecules are used as light absorption units in model compounds to realize light-induced charge separation; in addition, the porphyrin compound has wide application prospects in the aspects of Organic Field Effect Tubes (OFETs), molecular switches, molecular logic gates, molecular leads, organic solar cells, nonlinear optical materials, molecular recognition, medicines and the like.
Perylene diimide is an industrial dye with wide application, and is commonly used as a high-grade dye for automobile decoration. The gulf site of the perylene diimide molecule is easy to modify, characteristic structure modification can be carried out through gulf site coupling reaction, and the red region of the visible spectrum can be extended. In addition, the perylene diimide and the derivative thereof also have a series of excellent photoelectric properties such as higher molar extinction coefficient, high fluorescence quantum yield, stronger electronic affinity, good light stability and the like, and the properties enable the perylene diimide to be applied to various fields including n-type semiconductor materials, solar cells, organic light emitting diodes, field effect transistors and the like.
Porphyrin and perylene diimide are common light absorption units, have a large conjugated system and high molar extinction coefficient and high charge mobility, and are easily modified by a common chemical method to change the physical and chemical properties of the porphyrin and perylene diimide. Perylene diimide groups are introduced into meso sites of the porphyrin, so that the porphyrin derivative has excellent photoelectric properties of both the porphyrin and the perylene diimide. And phenanthrene ring groups are introduced into beta positions of porphyrin, so that molecules have a larger conjugated system, the energy level difference between the ground state and the excited state of the molecules is effectively reduced, and the porphyrin compound can generate a strong electron absorption spectrum and a strong fluorescence emission spectrum in a near-infrared region. However, no report has been made on this compound. In addition, the near-infrared dye molecule plays an important role in a plurality of fields such as optical imaging, tumor diagnosis, military reconnaissance, infrared camouflage, nonlinear optical materials, photodynamic therapy and the like. However, the synthesis of the compounds is less researched due to more steps and difficult separation of meso-site group modification and beta-site phenanthrene ring conjugated porphyrin, and the compounds can have strong absorption and fluorescence emission in the near infrared region after chemical modification, so that the compounds have wide application prospects in the aspects of organic solar cells, nonlinear optical materials, light absorption antennas, photodynamic therapy and the like.
