Porous organic copolymer (denoted as CPOL-BP&P) was afforded through the copolymerization of vinyl biphephos and tris(4-vinylphenyl)phosphine monomers under solvothermal conditions, and followed with impregnation method provided a highly efficient Rh/CPOL-BP&P catalyst with high activity (TOF = 11,200 h⁻¹) and regioselectivity (the ratio of linear to branched aldehydes, l:b = 62.2) for heterogeneous hydroformylation of 1-butene. High regioselectivity was also obtained in the hydroformylation of butene mixture (2-butene: l:b = 55.8, isomeric mixture of butenes: l:b = 56.0). The Rh/CPOL-BP&P catalysts were thoroughly characterized by means of nitrogen sorption isotherms, in situ FT-IR, XPS, solid-state ³¹P MAS NMR, HAADF-STEM, SEM and TEM. The formation of unique coordination bonds with Rh species in the polymer skeleton was determined. Heterogeneous hydroformylation of butenes was effectively realized due to a synergetic effect between PPh₃ moiety and biphephos moiety.

在溶剂热条件下，通过乙烯基联苯膦和三（4-乙烯基苯基）膦单体的共聚反应制得多孔有机共聚物（称为CPOL-BP＆P），然后采用浸渍法提供了一种高效，高活性的Rh / CPOL-BP＆P催化剂（ TOF = 11,200 h ^-1）和区域选择性（1-丁烯加氢甲酰化的区域选择性（线性与支链醛的比率，l：b = 62.2））。在丁烯混合物的加氢甲酰化中也获得了很高的区域选择性（2-丁烯：1：b = 55.8，丁烯的异构体混合物：1：b = 56.0）。Rh / CPOL-BP＆P催化剂通过氮气吸附等温线，原位FT-IR，XPS，固态³¹进行了全面表征P MAS NMR，HAADF-STEM，SEM和TEM。确定了在聚合物骨架中与Rh物种形成的独特配位键。由于PPh ₃部分和biphephos部分之间的协同作用，丁烯的异质加氢甲酰化得以有效实现。
