Embodiment 1

[0019] Embodiment 1: the synthesis of complex 1

[0020] The synthetic route is as follows:

[0021]

[0022] CH in the reaction formula 2 Cl 2 - dichloromethane; Au(C 6 f 5 )(tht)-tetrahydrothiophene pentafluorophenyl gold

[0023] Concrete synthetic steps are as follows:

[0024] 1. Under nitrogen atmosphere conditions, 0.3g (1.92mmol) of 2,3′-bipyridine, Au(C 6 f 5 )(tht) 1.78g (3.94mmol) and 30ml of dichloromethane that has been exhausted are added to vacuumize and fill with N 2 In the final reaction vessel, react at room temperature for 10-12 hours. After the reaction finishes, spin out the dichloromethane solvent and separate by column chromatography (the eluent is a mixed solvent of sherwood oil and dichloromethane, and the volume ratio is 1:1). 1.61 g of the target product, complex 1, was obtained as a white solid. Yield: 94.79%. 1 H NMR (400MHz, CDCl 3 ):δ(ppm)=9.31(s,1H),8.78-8.62(m,3H),7.90-7.69(m,3H),7.41(t,J=6Hz,1H).Anal.Calcd for C 22 h 8 Au 2 f ...

Abstract

The present invention relates to a dinuclear monovalent gold complex containing a bipyridine group, which has both aggregation-induced luminescence and mechanochromic properties, and its application. A dinuclear monovalent gold complex containing a bipyridine group, which has both aggregation-induced luminescence and mechanochromic properties, has the structure described in formula 1. This metal complex exhibits an aggregation-induced luminescence effect from colorless to yellow, and the photoluminescence of the solid sample can be changed from green to bright yellow after mechanical grinding, and the yellow luminescence after grinding The green luminescence can be restored after the methyl chloride solvent vapor treatment. Therefore, such gold-containing complexes are expected to be used in the fields of luminescent materials and mechanical sensors.

Description

technical field [0001] The present invention relates to a novel stimuli-responsive luminescent material and its application, in particular to a novel double-nuclear monovalent gold complex containing bispyridine groups with both aggregation-induced luminescent and mechanochromic properties and its application. Background technique [0002] Mechanochromic materials that respond to mechanical force have aroused extensive research interest of scientists due to their potential application value in the fields of mechanical sensors, anti-counterfeiting and information storage. Under the action of external mechanical force, the optical properties of smart materials with mechanochromic properties will change. So far, many pure organic compounds with mechanochromic properties have been reported. In comparison, the number of metal complexes with mechanochromic properties is very limited. In addition, traditional luminescent materials often emit strongly in solution, but under the con...
