Phenolic compound containing tyramine structure, phthalonitrile and preparation method and application of phthalonitrile

The invention discloses a phenolic compound containing a tyramine structure, phthalonitrile as well as a preparation method and application the phthalonitrile. The structural general formula of the phenolic compound is as follows, the structural general formula of the phthalonitrile containing the tyramine structure is as follows, and monoanhydride/dianhydride reacts with tyramine under a reflux condition so as to obtain the monophenol/bisphenol compound containing the tyramine structure. The phenolic compound containing the tyramine structure reacts with 4-nitro phthalonitrile under a heatingcondition to obtain the phthalonitrile containing the tyramine structure. According to the phenolic compound containing the tyramine structure provided by the invention, an imide structure and an aliphatic chain are introduced through tyramine, the phenolic compound is a novel phenolic monomer, the selectable types of the monomer are increased, and raw materials for preparing phthalonitrile monomers are expanded; and the
