Benzophenanthrene dodecyloxy bridged dodecyloxy phenyl porphyrin binary compound discotic liquid crystal material synthesis method

The invention discloses a benzophenanthrene dodecyloxy bridged dodecyloxy phenyl porphyrin binary compound discotic liquid crystal material synthesis method. The method includes: step one, generating monohydroxy pentahexyloxy benzophenanthrene, and synthesizing alkoxy benzophenanthrene containing an omega-bromine branch chain; step two, obtaining porphyrin acid; step three, and synthesizing a benzophenanthrene dodecyloxy bridged dodecyloxy phenyl porphyrin binary compound discotic liquid crystal material by phase-transfer catalysis reaction of intermediates obtained by the two steps. Benzophenanthrene which is a common material has advantages of high photochemical and thermal stability, easiness in raw material acquisition, easiness in product purification and the like. Porphyrin is high in adsorption in a visible region and photochemical and thermal stability in, the synthesis method is developed, and the synthesized benzophenanthrene dodecyloxy bridged dodecyloxy phenyl porphyrin binary compound discotic 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.
