Problems solved by technology

[0003] The naphthalene system has great conjugation characteristics. Naphthalene dioic acid has been reported as a bridging ligand to construct fluorescent coordination materials. However, its coordination mode and connection configuration are relatively simple. As a bridging ligand, it has the following disadvantages: (1) The number of metal sites that can be connected is small; (2) Pure carboxyl coordination will lead to poor stability of the coordination material; (3) The coordination mode is relatively limited

Abstract

The invention discloses a zinc salt fluorescent functional coordination material and a preparation method thereof. The preparation method of the zinc salt fluorescent functional coordination material comprises the following steps: 1) preparing a reaction solution: mixing 6-(1H-tetrazole-5 ‑base)‑2‑naphthoic acid and zinc salt are added to the solvent, fully stirred and dissolved at room temperature to obtain a reaction solution; 2) crystallization reaction: the reaction solution obtained in step 1) is placed in an oven with a temperature of 140‑160 °C React for 3-5 days to obtain massive colorless crystals, and then filter and wash in sequence to obtain the zinc salt fluorescent functional coordination material. The zinc salt fluorescent functional coordination material of the present invention is formed by the self-assembly coordination of zinc salt and 6-(1H-tetrazol-5-yl)-2-naphthoic acid, which exhibits high stability to humidity and temperature , and can exhibit strong fluorescence properties.

Description

technical field [0001] The invention relates to the technical field of fluorescent functional coordination materials, in particular to a zinc salt fluorescent functional coordination material and a preparation method thereof. Background technique [0002] Functional coordination materials are favored and concerned by many material scientists because of their adjustable structure-property relationship. Fluorescent functional coordination materials have become a research hotspot in this type of materials due to their advantages such as clear and adjustable structure and controllable fluorescence performance. The construction of fluorescent functional coordination materials generally needs to contain two parts: the first part is metal ions with potential fluorescent properties (such as d 10 Electronic configuration), rare earth ions, etc.; the second part is an organic ligand with a conjugated system. Among them, zinc salt is used as a precursor for assembling fluorescent coo...
