在多孔配位聚合物（pcp）的一维通道中进行了1,6-二烯双官能团单体的自由基环聚合。虽然单体的本体聚合或溶液聚合通常会得到交联的不溶性聚合物，但不利的聚合物间反应在pcp的窄纳米通道中被有效抑制，从而提供可溶的线性聚合物。通过改变有机配体，可以很容易地设计pcp的孔基质和功能，从而研究了二烯单体在不同孔径下的聚合。所得到的聚合物的主要结构，如分支结构、循环结构和立体规则性，根据pcp的孔隙特征而改变。
Radical cyclopolymerization of difunctional monomers based on 1,6-diene components was performed in one-dimensional channels of porous coordination polymers (PCPs). Although bulk or solution polymerization of the monomers usually gives cross-linked insoluble polymers, the unfavorable interpolymer reactions were effectively suppressed in the narrow nanochannels of PCPs to provide soluble linear polymers. The pore matrices and functionality of PCPs can be readily designed by changing the organic ligands, so that polymerization of the diene monomers in different sized pores was examined. The primary structures of the resulting polymers, such as branching, cyclic structure, and stereoregularity, were changed, depending on the pore characteristics of the PCPs.
