Synthesis method of benzophenanthrene hexaalkoxyl bridged dodecoxyl phenyl porphyrin binary compound disc-shaped liquid crystal material

The invention discloses a synthesis method of a benzophenanthrene hexaalkoxyl bridged dodecoxyl phenyl porphyrin binary compound disc-shaped liquid crystal material. A synthesis route is divided into the following three parts: in the first part, generating monohydroxy pentahexaalkoxyl benzophenanthrene and then synthesizing alkoxyl benzophenanthrene containing one omega-bromine branched chain; in the second part, obtaining porphyrin acid; and in the third part, carrying out a phase transfer catalytic reaction on intermediates obtained by the two parts to synthesize an alkoxyl bridged porphyrin-benzophenanthrene binary compound. The benzophenanthrene is used as a common material and has the advantages that photochemical properties and heat stability are good, the raw materials are easy to obtain and the product is easy to purify and the like, the porphyrin has good strong absorption property, photochemical properties and heat stability in a visible light region and the synthesis method is developed; and the synthesized benzophenanthrene hexaalkoxyl bridged dodecoxyl phenyl porphyrin binary compound disc-shaped liquid crystal material can be applied to molecular devices including organic photovoltaic materials, liquid crystal materials, organic solar cells, organic light-emitting diodes and the like.
