{"doi":"10.1039/d0dt03577g","title":"Efficient photorelease of carbon monoxide from a luminescent tricarbonyl rhenium( <scp>i</scp> ) complex incorporating pyridyl-1,2,4-triazole and phosphine ligands","abstract":"Precise control over the production of carbon monoxide (CO) is essential to exploit the therapeutic potential of this molecule. The development of photoactive CO-releasing molecules (PhotoCORMs) is therefore a promising route for future clinical applications. Herein, a tricarbonyl-rhenium(i) complex (1-TPP), which incorporates a phosphine moiety as ancilliary ligand for boosting the photochemical reactivity, and a pyridyltriazole bidentate ligand with appended 2-phenylbenzoxazole moiety for the purpose of photoluminescence, was synthesized and characterized from a chemical and crystallographic point of view. Upon irradiation in the near-UV range, complex 1-TPP underwent fast photoreaction, which was monitored through changes of the UV-vis absorption and phosphorescence spectra. The photoproducts (i.e. the dicarbonyl solvento complex 2 and one CO molecule) were identified using FTIR, 1H NMR and HRMS. The results were interpreted on the basis of DFT/TD-DFT calculations. The effective photochemical release of CO associated with clear optical variations (the emitted light passed from green to orange-red) could make 1-TPP the prototype of new photochemically-active agents, potentially useful for integration in photoCORM materials.","journal":"Dalton Transactions","year":2021,"id":177008,"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":20,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9545,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2021-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":720517,"name":"Alexandre Poirot","orcid":"0000-0003-0164-3115","position":1,"is_corresponding":false},{"id":721269,"name":"Meriem Rmili","orcid":null,"position":2,"is_corresponding":false},{"id":721270,"name":"Nadine Leygue","orcid":null,"position":3,"is_corresponding":false},{"id":720518,"name":"Mariusz Wolff","orcid":"0000-0002-9265-7557","position":4,"is_corresponding":false},{"id":720519,"name":"Nathalie Saffon‐Merceron","orcid":"0000-0002-0301-4163","position":5,"is_corresponding":false},{"id":720520,"name":"Éric Benoist","orcid":"0000-0003-0764-9024","position":6,"is_corresponding":false},{"id":720521,"name":"Suzanne Fery‐Forgues","orcid":"0000-0002-7399-5956","position":7,"is_corresponding":false},{"id":721268,"name":"Ángel D.
