Monodisperse porous organic metal polymer material as well as preparation method and application thereof

The invention belongs to the technical field of heterogeneous catalysts, and particularly relates to a monodisperse porous organic metal polymer material and a preparation method and application thereof. The polymer is prepared by taking homogeneous double carbene iridium, palladium, gold, copper, cobalt and manganese compounds as monomers and aromatic hydrocarbon as a comonomer in a manner of adding a cross-linking agent and carrying out Friedel-Crafts alkylation under the catalysis of Lewis acid. The polymer can be used for catalyzing hydrogenation cyclization of levulinic acid to prepare gamma-valerolactone, or catalyzing oxidative dehydrogenation of polyol and derivatives thereof and carbohydrate compounds to efficiently prepare lactic acid and derivatives thereof, and dehydrogenationcoupling of alcohol compounds and amine to efficiently prepare pyrrole and derivatives thereof. The polymer material completely holds intrinsic high activity and high selectivity of a homogeneous catalyst precursor and has th
