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 a tedious post-modification treatment.
