Embodiment 1

[0023] Dissolve 0.3g of Salen ligand and 0.5g of triethylenediamine in 35ml of N,N-dimethylformamide and ethanol mixed solvent with a volume ratio of 2:1, stir in a 50ml beaker until uniformly dissolved, and Add 10ml of 0.3g Zn(NO 3 ) 2 ·6H 2 The clear solution of N,N-dimethylformamide and ethanol mixed solvent with a volume ratio of 2:1, seal the beaker with a perforated plastic wrap, let it stand at an ambient temperature of 15 to 25 degrees, and slowly volatilize. After about 3-7 days, small yellow crystals are precipitated, and the product yield is about 75% based on zinc nitrate.

[0024] The selection size is 0.20×0.20×0.20mm 3 The crystal was used for single crystal structure analysis, and the single crystal diffraction data were collected on the Rigaku Oxford Diffraction, 2020 diffractometer. The method was XtaLAB Synergy R, DW system, HyPix, Hybrid Pixel Array Detector, and the ray used Rigaku (Mo) X-ray Source .

Abstract

The invention discloses a novel coordinated circular polarization luminescent crystalline compound [ZnSalen] [DABCO] [EtOH], the molecular formula of the compound is C44H70N4O3Zn, Salen is 3, 5-di-tert-butyl salicylaldehyde-S, S-1, 2-cyclohexyl imine, DABCO is triethylene diamine, a central metal zinc atom of the compound is of a five-coordinated pyramid type configuration, N2O2 of a Salen ligand occupies four corners of the bottom surface, and another N atom of DABCO occupies the vertex. The complex presents a T-shaped conformation, and the other N atom of DABCO and an ethanol guest molecule form hydrogen-bond interaction. The complex has polarity, adopts a P21 space group, emits cyan light under 365nm ultraviolet irradiation, and can emit light in a light-induced circular polarization manner. The invention also discloses a preparation method of the metal organic compound crystal. The prepared [ZnSalen] [DABCO] [EtOH] metal fluorescent crystalline state complex has good potential application in the aspects of optical materials (such as nonlinear optical materials, circular polarization luminescence, fluorescence sensing and the like).

Description

technical field [0001] The invention belongs to the field of functional materials, and in particular relates to a novel coordination circularly polarized light-emitting crystalline compound and its preparation method and application. Background technique [0002] Salen ligands are porphyrin analogs with N 2 o 2 It is an excellent tetradentate coordination site and can coordinate with many metal ions. This type of complex has been widely used in homogeneous catalysis, but there are few reports on compounds used to construct other functions. The synthesis of metal-Salen complexes has matured remarkably, allowing large-scale preparation of libraries of highly functionalized symmetric and asymmetric building blocks. The precursors required for the construction of these metal-Salen complexes are widely available and relatively inexpensive, so that various structures can be obtained cost-effectively, which can also be easily fine-tuned. Among them, Zn(II)-centered complexes wer...
