Problems solved by technology

The reprecipitation method used to synthesize porphyrin self-assembly requires that the two solvents added must be compatible, which greatly limits the range of solvent selection, thereby limiting the solubility of porphyrin, and the product yield is too low, which limits its application; The ion self-assembly method is to assemble two oppositely charged ions through electrostatic drive. There are very few types of ion porphyrins suitable for this method, and the synthesis of these anion and cation porphyrins is also relatively difficult, which makes this method subject to certain restrictions; The vapor phase depositi

Abstract

The invention discloses a method for preparing a phenylamino porphyrin self-assembled nanomaterial by adopting a co-solvent method. The method comprises the following steps: 1) preparing CTAB, SDS, MTAB or P123 aqueous solution; 2) preparing a DMF solution of phenylamino porphyrin; and 3) adding the solution in the step 2) into the solution in the step 1), stirring for 40-50h at 25 DEG C, and performing centrifugal separation, to obtain a solid, namely the phenylamino porphyrin self-assembled nanomaterial. The method has the advantages of the original methods, the yield problem can be solved as a great amount of phenylamino porphyrin is dissolved in the DMF solution; by taking micelle as a confinement template, the self assembling can be conducted under the assistance of an emulsifying agent by changing the soluble state of phenylamino porphyrin molecules into a non-soluble state through the weak phase interaction between molecules, finally the porphyrin molecule assembled body with controllable shapes can be obtained, and the assembled material has an important role in the fields of photocatalysis, nanodevices and the like.
