Embodiment 1

[0017] Add 1g of chloromethylated cross-linked polystyrene microspheres to 20ml dimethyl sulfoxide, and after swelling the microspheres, add 2g of acid-binding agent NaHCO 3 And 2.5g catalyst KI, through N 2 After 30min, the temperature was raised to 110°C, under N 2 After reacting at constant temperature under atmosphere and stirring for 6 hours, suction filtration, washing with water, and vacuum drying yielded aldehyde-modified cross-linked polystyrene microspheres AL-CPS. Chloromethyl conversion rate can reach 89%.

Embodiment 2

[0019] Add 1 g of chloromethylated cross-linked polystyrene microspheres to 20 ml of dimethyl sulfoxide to swell the microspheres, then add 1.8 g of acid-binding agent NaHCO 3 And 2.2g catalyst KI, through N 2 After 30min, the temperature was raised to 110°C, under N 2 After reacting at constant temperature under atmosphere and stirring for 6 hours, suction filtration, washing with water, and vacuum drying yielded aldehyde-modified cross-linked polystyrene microspheres AL-CPS. Chloromethyl conversion rate can reach 86.5%.

Embodiment 3

[0021] Add 1 g of chloromethylated cross-linked polystyrene microspheres to 20 ml of dimethyl sulfoxide to swell the microspheres, then add 1.8 g of acid-binding agent NaHCO 3 And 2.0g catalyst KI, through N 2 After 30min, the temperature was raised to 100°C under N 2 After reacting at constant temperature under atmosphere and stirring for 5 hours, suction filtration, washing with water, and vacuum drying gave aldehyde-modified cross-linked polystyrene microspheres AL-CPS. Chloromethyl conversion rate can reach 85%.

Abstract

The invention belongs to the technical field of the immobilization of metalloporphyrin on a carrier, and in particular relates to a method for immobilizing metalloporphyrin by crosslinked polystyrene microspheres, which solves the problems of low immobilized amount, complex process and inconvenient operation in the conventional method for immobilizing the metalloporphyrin. The method comprises the following steps of: adding chloromethylated crosslinked polystyrene microspheres into dimethyl sulfoxide, adding NaHCO3 and KI for reaction, and drying to obtain AL-CPS; swelling the AL-CPS in a solvent, adding benzaldehyde and a catalyst, raising the temperature, dripping the solvent dissolved with pyrrole for reaction, and drying to obtain crosslinked polystyrene microspheres immobilized with porphyrin; adding the crosslinked polystyrene microspheres immobilized with the porphyrin into N,N-dimethylformamide, adding metal salts or oxides formed by transition metal atoms or lanthanide seriesmetal atoms for reaction, and drying to obtain the crosslinked polystyrene microspheres immobilized with metalloporphyrin. The method is novel and quick; and the prepared material has high stability and can be repeatedly used.

Description

technical field [0001] The invention belongs to the technical field of metalloporphyrin immobilization on carriers, and in particular relates to a method for crosslinked polystyrene microspheres to immobilize metalloporphyrin. Background technique [0002] Porphyrins are an important class of macrocyclic compounds that widely exist in nature and living organisms. The unique chemical structure of porphyrin compounds makes them have special physiological activities and physical and chemical properties, such as oxygen-carrying, electron-transporting, catalytic, molecular recognition, photosensitivity and other properties, so they are used in various fields, such as medicine (photo dynamic therapy), biochemistry (molecular recognition), material chemistry (photoelectric materials), synthetic chemistry (bionic catalysis), analytical chemistry (sensors), energy science (solar energy conversion), optical information technology (optical information data storage), etc. [Takechi K, S...
