Abstract

The invention discloses a synthetic method for a 1,3,5-triarylbenzene compound. The method comprises the following steps: dissolving a chalcone derivative and inorganic alkali in dimethyl sulfoxide, carrying out reaction at 40 to 80 DEG C in the air for 3 to 8 hours, and carrying out separation and purification so as to obtain the 1,3,5-triarylbenzene compound, wherein a molar ratio of the chalcone derivative to the inorganic alkali is 1: 1-6; every mole of the chalcone derivative requires 4 to 8 mL of dimethyl sulfoxide; and the chalcone derivative has a general structural formula described in the specification, wherein Ar1 and Ar2 are aryl groups. The synthetic method for the 1,3,5-triarylbenzene compound provided by the invention has the following advantages of easily-available raw materials, simple operation, mild reaction conditions, no need of any transition metal catalyst, strong reaction specificity, strong applicability to a basic-group-contained substrate, no generation of waste products like halogen or boric acid, and simple, convenient and green after-treatment.

Description

technical field

[0001] The invention belongs to the technical field of organic synthesis, and in particular relates to a synthesis method of 1,3,5-triarylbenzene compounds. Background technique

[0002] 1,3,5-Triarylbenzene compounds are a class of aromatic compounds with a special structure of C3 symmetry. They have 3 symmetry axes and 3 symmetry planes and are highly symmetrical, so they can be used to construct dendrimers and various Core module for polyphenylene compounds. The nonlinear macromolecules of its triaryl benzene mother ring have highly delocalized Π electrons and excellent optical, electrical, and magnetic properties. It is a class of electroluminescent organic molecular materials with great potential and important organic synthesis intermediates. It can also be used as an important basic functional module of hyperbranched polymer light-emitting materials.

[0003] As early as the beginning of the 20th century, 1,3,5-triarylbenzene compounds have been synth...
