Conjugated polyacetylene-based monocyclic and bicyclic polymers were synthesized by blocking-cyclization metathesis polymerization using short ladderphanes as the initial motif and multi-cyclizing unit, and fully characterized to elucidate the cyclic characteristics and good photoelectric properties. Importantly, the molecular topology of rationally designed cyclic polymers was directly observed without
以短梯烷为起始基序和多环化单元,通过封闭环化复分解聚合合成了共轭聚乙炔基单环和双环聚合物,并对其进行了充分表征,阐明了其环状特性和良好的光电性能。重要的是,无需繁琐的后修饰处理即可直接观察到合理设计的环状聚合物的分子拓扑结构。
