Abstract

The invention discloses a 2-D zinc coordination polymer with a dual penetration structure as well as a synthesis method and application of the 2-D zinc coordination polymer, relates to a synthesis method and application of the 2-D zinc coordination polymer and aims at the technical problem that the traditional organic light-emitting material presenting blue-fluorescence is high in synthesis cost. The 2-D zinc coordination polymer with the dual penetration structure has a molecular formula of C20H10N6O4Zn. The synthesis method of the 2-D zinc coordination polymer comprises the following steps of: 1, preparing a ligand 4-(1-triazolemethyl) benzoic acid; and synthesizing the 2-D zinc coordination polymer with the dual penetration structure. The 2-D zinc coordination polymer with the dual penetration structure can be used as a metal organic blue light emitting material. The 2-D zinc coordination polymer and the synthesis method are applied to the field of preparation of organic light-emitting materials.

Description

technical field [0001] The invention relates to a synthesis method and application of a 2-D zinc coordination polymer. Background technique [0002] The research on the synthesis and performance of metal-organic light-emitting materials has always been a hot spot in the field of light-emitting materials, and blue light compounds with long fluorescence lifetime and stable structure have great applications in organic photoluminescence. Organic light-emitting materials exhibiting blue fluorescence have always been dominated by noble metals, which require high costs. In the preparation of blue organic light-emitting materials, it is very challenging to design and synthesize efficient blue organic light-emitting materials by using the tunability of metal ions and ligands of metal coordination polymers. Based on the above reasons, we chose 4-(1-triazolylmethylene)benzoic acid, which is semi-rigid and has a large conjugated π bond, as a ligand, and designed and synthesized an orga...
