Diphenyltrisilane 1 showed an intense fluorescence band assignable to the intramolecular charge-transfer (ICT) band in a polar solvent. Whereas silylene extrusion and 1,3-silyl migration were the major photoreactions of 1 in a nonpolar solvent, solvolytic cleavage of the Si−Si bond occurred significantly in an ethanol−hexane mixture; the ICT state is responsible for the latter reaction. Solvent and temperature dependence of the product distribution has indicated that both the silylene extrusion and the 1,3-silyl migration take place from the nonpolar but electronically different excited states of 1 . On the basis of the photoreactions of 1 using a nonresonant two-photon (NRTP) excitation method, it is suggested that the silylene extrusion occurs via the 1 L a state of 1 as a silyl-substituted benzene.","is_dataset_classified":null,"base_score":2.9444389791664403,"endowment":2.9444389791664403,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"21097893","pmcid":null,"openalex_id":"https://openalex.org/W2012766717","authors":[],"funders":[],"total_grants":0,"fwci":1.3016,"citation_percentile":0.76285118,"influential_citations":0,"citation_trend":[{"year":2015,"count":1},{"year":2016,"count":1},{"year":2025,"count":1}],"oa_status":"closed","license":null,"oa_locations":[{"url":"https://pubs.acs.org/doi/pdf/10.1021/ja983370k","host_type":"publisher"},{"url":"https://doi.org/10.1021/ja983370k","host_type":"journal"},{"url":"http://t2r2.star.titech.ac.jp/cgi-bin/publicationinfo.cgi?q_publication_content_number=CTT100710062","host_type":"repository"}],"fields_of_study":["Synthesis and characterization of novel inorganic/organometallic compounds","Photochemistry and Electron Transfer Studies","Synthesis and Properties of Aromatic Compounds"],"mesh_terms":[],"keywords":["Silylene","Chemistry","Photochemistry","Silylation","Intramolecular force","Solvent","Excited state","Extrusion","Hexane","Benzene","Triplet state","Bond cleavage","Protic solvent","Silicon","Molecule","Organic chemistry","Catalysis"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-22T18:34:10.847765Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
