The invention discloses a pyrene-based multi-arm structure triindenyl organic photoelectric material and its preparation method and application. The organic photoelectric material is a multi-arm structure derivative with pyrene as the core and triindenyl as the arm . The preparation method is to use 1,3,6,8-tetrabromo-pyrene as a raw material, and 2-boronate-triindene to undergo a coupling reaction to obtain product A; use 1,3,6,8-tetrabromo- Pyrene is used as a raw material, and a coupling reaction occurs with 2-alkynyl-triindene to obtain product B. Because pyrene and triindene have a large π-conjugated structure, they have good electron and hole transport properties, and both products exhibit excellent photoelectric properties; Make the product have good solubility properties. Because of its unique structure and photoelectric performance, it has great practical application value in the field of photoelectricity. |
