    摘要: A catalyst which can catalyze ring-addition reaction of CO2 and an alkylene oxide at 0˜180° C. under 0.1˜8.0 MPa to produce a corresponding cyclic carbonate, and the preparation thereof. The catalyst is a conjugated microporous macromolecule polymer complexed with cobalt, chromium, zinc, copper or aluminium, and by using the macromolecule catalyst complexed with different metals to catalyze the reaction of CO2 and alkylene oxide at normal temperature and normal pressure, a yield of the corresponding cyclic carbonate of 35%-90% can be obtained. The catalyst is easy to recover and the re-use of the catalyst has no influence on the yield; additionally, the yield can reach over 90% by controlling the reaction conditions.

    摘要: A molecular recognition polymer enabling the reconstruction of the recognition field for a target molecule which is produced by applying the molecular imprinting method is disclosed. A molecular recognition polymer enabling the reconstruction of the recognition field for a target molecule which has a molecule interacting with the target molecule in the polymer and in which the recognition field for a target molecule has been constructed and the above-described molecule interacting with the target molecule is detachable and replaceable. This molecular recognition polymer can be produced by synthesizing a complex of the target molecule with a molecule capable of specifically and reversibly binding to the target molecule, copolymerizing this complex with a molecule interacting with the target molecule and a crosslinking agent to give a polymer, and then detaching the target molecule and the molecule interacting with the target molecule from the polymer thus obtained.
