Abstract

The invention discloses a 5,10,15,20-tetra-aryl diphenanthrene (9,10-b:9,10-1)-22,24-diseleno porphyrin compound which is obtained by the reaction of phenanthro-pyrrole and 2,5-di(aryl hydroxyl methyl) selenophen under low temperature and catalysis of BF3 Et2O in anaerobic atmosphere. The Soret spectral bands of the compound appear in 521nm, compared with tetraphenyl diseleno porphyrin without conjugated aromatic ring at beta-site, the Soret spectral bands are red shifted by 52nm and enter a green light zone above 500nm. The compound has wide application prospects in such areas as photodynamics therapy photosensitizer, OFETs (organic field effect tubes), molecular antenna, light energy converter, optical conversion material, molecular switch, molecular logic gate, molecular wire, organic solar battery, organic electroluminescence, non-linear optical material, optical storage, molecular identification and medicine and so on.

Description

1. Technical field [0001] The present invention relates to 5,10,15,20-tetraaryldiphenanthrene[9,10-b:9,10-l]-22,24-diselenoporphyrin derivatives and a preparation method thereof. 2. Background technology [0002] Porphyrin compounds have many unique photoelectric properties, good light and thermal stability, and have a large molar absorptivity in the visible light range, so they have been widely used in biochemistry, medicine, analytical chemistry, photocatalysis, and material science. It has received extensive attention and application. In recent years, using the unique electronic structure and photoelectric properties of porphyrin molecules, the design and synthesis of photoelectric functional materials and the development of photoelectric devices have become very active research fields at home and abroad. In terms of energy transfer, porphyrin molecules, as light-absorbing units in model compounds, can realize photo-induced charge separation [see: (a) Gust D.Moore T.A.Sc...
