{"doi":"10.1021/jacs.3c03978","title":"<i>cis</i> -Selective Acyclic Diene Metathesis Polymerization of <b>α</b> , <b>ω</b> -Dienes","abstract":"The cis / trans stereochemistry of repeating alkenes in polymers provides a powerful handle to modulate the thermal and mechanical properties of these soft materials, but synthetic methods to precisely dictate this parameter remain scarce. We report herein a cis -selective acyclic diene metathesis (ADMET) polymerization of readily available α,ω-diene monomers with high functional group tolerance. Identification of a highly stereoselective cyclometalated Ru catalyst allowed the synthesis of a broad array of polymers with cis contents up to 99%. This platform was leveraged to study the impact of the cis geometry on the thermal and mechanical properties of polyalkenamers, including an ABA triblock copolymer synthesized via extension of a cis -rich telechelic polyoctenamer with d, l -lactide. These results suggest that cis -selective ADMET affords an efficient strategy to tune the properties of a variety of polymers.","journal":"Journal of the American Chemical Society","year":2023,"id":349572,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":10,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9534,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2023-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":872844,"name":"Ting-Wei Hsu","orcid":"0000-0003-0523-1118","position":1,"is_corresponding":false},{"id":1093617,"name":"Jake L.
