开发了具有弹簧状邻苯撑（oP）折叠体的交联聚合物网络。NMR分析表明oP交联剂折叠良好。与基于OP的交联剂的聚合物网络相比，二乙烯基苯交联网络显示出增强的能量耗散和弹性。能量耗散归因于应变诱导的oP单元的可逆展开。能量耗散随着折叠体中螺旋圈数的增加而增加。
Polymer networks crosslinked with spring-like ortho-phenylene (oP) foldamers were developed. NMR analysis indicated the oP crosslinkers were well-folded. Polymer networks with oP-based crosslinkers showed enhanced energy dissipation and elasticity compared to divinylbenzene crosslinked networks. The energy dissipation was attributed to the strain-induced reversible unfolding of the oP units. Energy dissipation increased with the number of helical turns in the foldamer.
