Novel layered crystalline organic polymer-inorganic hybrid material comprising calcium phosphate with unique architectures for superior performance catalyst support

摘要

An organic copolymer-inorganic hybrid material, calcium phosphonate-phosphate (CaPS-PVPA), is fabricated under mild conditions. In particular, CaPS-PVPA is not prepared with traditional methods such as a hydrothermal one, but with amorphous reactions for a simple, fast, cost-effective and environmentally benign approach. Characterization shows that CaPS-PVPA is a layered crystalline mesoporous material, and could be readily used as a catalytic support. A catalyst with immobilization of chiral salen Mn(III) onto CaPS-PVPA demonstrate a superior catalytic disposition (conv. > 99% and ee > 99%), which offers great potential for industry scale applications.
