Spectroscopic and (3)MLCT luminescent properties of these Pt(II) cyclometalated complexes were found to be pH dependent. This was attributed to the protonation/deprotonation of the acidic 1-imidazolyl-NH moieties on the ligands. All the cycloplatinated complexes (both protonated and deprotonated forms) possessed two-photon excitability with two-photon absorption cross-sections ranging from 6.0 to 30.0 GM (protonated forms) and from 16.2 to 24.9 GM (deprotonated forms).","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":"22159163","pmcid":null,"openalex_id":"https://openalex.org/W2070921557","authors":[],"funders":[],"total_grants":0,"fwci":0.945,"citation_percentile":0.73939203,"influential_citations":0,"citation_trend":[{"year":2013,"count":4},{"year":2014,"count":2},{"year":2015,"count":1},{"year":2016,"count":1},{"year":2017,"count":1},{"year":2019,"count":1},{"year":2020,"count":3},{"year":2021,"count":1},{"year":2023,"count":3},{"year":2024,"count":1}],"oa_status":"closed","license":null,"oa_locations":[{"url":"http://pubs.rsc.org/en/content/articlepdf/2012/DT/C1DT11037C","host_type":"publisher"},{"url":"https://doi.org/10.1039/c1dt11037c","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/22159163","host_type":"repository"},{"url":"http://hdl.handle.net/10397/32089","host_type":"repository"}],"fields_of_study":["Photochromic and Fluorescence Chemistry","Nonlinear Optical Materials Studies","Luminescence and Fluorescent Materials"],"mesh_terms":[],"keywords":["Deprotonation","Protonation","Chemistry","Medicinal chemistry","Stereochemistry","Luminescence","Photochemistry","Organic chemistry","Ion","Materials science"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Clean water and sanitation"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-07-27T11:38:59.498608Z","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":[]}
