Embodiment 1

[0035] The preparation of embodiment 1 complex of the present invention

[0036] Molby H 3 ntb:bpeb:Cu(NO 3 )2 :CH 3 CN: H 2 O: HNO 3 Weigh the raw materials in the ratio of 25:17:37:6583:8317:3, put them in a 50mL glass beaker, stir for 0.5h, transfer to a 25mL reactor, react at 110°C for three days, and cool to room temperature naturally. Light green crystals were observed, which was the target product, which was filtered out from the mother liquor, washed with water, and then dried naturally.

Description

technical field [0001] The invention belongs to the technical field of metal-organic complex materials, and relates to a copper coordination polymer and its preparation method and application, in particular to a copper coordination polymer crystalline pigment [Cu 2 (Hntb) 2 (bpeb)] and its preparation method and application. Background technique [0002] Copper is a non-ferrous metal closely related to human beings, second only to aluminum in the consumption of non-ferrous metal materials in China. Pure copper, copper alloys and copper salts are widely used in electrical, machinery manufacturing, construction industry, national defense industry, chemical industry, medicine, decorative arts and other fields. Divalent copper salt is the most common copper compound, often blue or green, and natural inorganic minerals such as azurite and turquoise are widely used as green pigments. [0003] Green pigment is an important color pigment, generally divided into organic green pigm...
