Embodiment Construction

[0029] (1) Synthesis of 4'-(4-chlorophenyl)-2,2':6',2''-terpyridine (L)

[0030] ① Accurately weigh 3.080g of potassium hydroxide (KOH) on a ten-thousandth balance, accurately measure 100ml of ethanol in a graduated cylinder, place it in a 250mL round bottom flask, add a magnet, and stir for 40min at a speed of 1500r / min until completely dissolved ( clear transparent solution);

[0031] ②Install a separatory funnel device above the above 250ml round bottom flask, add 4.49ml (0.04mol) 2-acetylpyridine at a constant speed at a rate of 20 drops / min, after the addition is complete, remove the separatory funnel device, Put on a balloon, stir for 20 minutes, add 2.81g (0.02mol) p-chlorobenzaldehyde, the solution turns yellow, continue stirring;

[0032] ③ Slowly add 58ml of concentrated ammonia water to the above mixed solution, the solution immediately turns reddish brown, at this time increase the stirring speed to 2500r / min;

[0033] ④Install a condenser tube and react in a con...

Abstract

The invention relates to a preparation method of a Co-Ho dual-functional molecular magnetic material. The preparation method is characterized in that the structural formula of the Co-Ho dual-functional molecular magnetic material is [Co(4-Cl-PH-terpy)2][Ho3(p-NO2-PHCOO)14], wherein p-NO2-PHCOO is p-nitrophenyl formic acid anion, and 4-Cl-PH-terpy is 4-(4-chlorphenyl)-terpyridyl. The preparation method comprises the following steps: first oscillating CoCl2.6H2O, 4minute-(4-chlorphenyl)-2, 2minute: 6minute, 2second-terpyridyl and 10ml of H2O for 30 minutes until the components are completely dissolved, then transferring into a 23ml polytetrafluoroethylene reaction kettle to form a cation module; and adding Ho2O3 and p-nitrophenyl formic acid to form an anion module, and reacting for 3 days in a muffle furnace at the temperature of 180 DEG C. The Co<2+> anions having an automatic conversion function and rare-earth [Ho(CO2)4]- cations having a molecular magnetic function are combined to prepare the anion-cation automatic-conversion and molecular magnetic dual-functional molecular magnetic material.

Description

technical field [0001] The invention relates to a preparation method of a molecular magnetic material, which belongs to the technical field of functional material synthesis. Background technique [0002] Single-molecule magnets (Single-Molecule Magnets, SMMs) is a new research field emerging in recent years. Single-molecule magnets are new materials between molecular-based magnets and nanomagnetic materials. Since the structure of single-molecule magnets is an independent nano-magnetic unit, it has many specific properties, so it has become a research hotspot. In 1993, the Sessoli research group discovered the first single-molecule magnet [Mn 12 o 12 (O 2 CMe) 16 (H 2 O) 4 ]·2(CH 3 COOH) 4H 2 O See SessoliR et al., J. Am. Chem. Soc. 1993, 115, 1804. Since then, Sessoli and Girolami have systematically studied and analyzed the characteristics and properties of single-molecule magnets. See GirolamiGS et al., Science 1995, 268, 397. Single-molecule magnets have gradua...
