The quantity of porphyrin linked to the surface was determined from thermogravimetric and UV-vis analysis. A reversible protonation equilibrium between the attached porphyrin and the residual acid groups of the carbon nanotubes has been identified. Steady-state fluorescence emission spectrum of the solutions of porphyrin-linked carbon nanotubes shows that the porphyrins act as energy absorbing and electron transferring antennae, and the carbon nanotubes act as efficient electron acceptors. The porphyrin-linked carbon nanotubes show 95-100% emission quenching, indicating a fast photoinduced electron transfer.","is_dataset_classified":null,"base_score":5.817111159963204,"endowment":5.817111159963204,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"15884911","pmcid":null,"openalex_id":"https://openalex.org/W2089646493","authors":[],"funders":[],"total_grants":0,"fwci":14.3532,"citation_percentile":0.9957293,"influential_citations":0,"citation_trend":[{"year":2012,"count":19},{"year":2013,"count":24},{"year":2014,"count":15},{"year":2015,"count":13},{"year":2016,"count":14},{"year":2017,"count":8},{"year":2018,"count":51},{"year":2019,"count":6},{"year":2020,"count":8},{"year":2021,"count":8},{"year":2022,"count":10},{"year":2023,"count":5},{"year":2024,"count":8},{"year":2025,"count":1},{"year":2026,"count":1}],"oa_status":"closed","license":null,"oa_locations":[{"url":"https://pubs.acs.org/doi/pdf/10.1021/ja0508222","host_type":"publisher"},{"url":"https://doi.org/10.1021/ja0508222","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/15884911","host_type":"repository"},{"url":"http://digitalcommons.unl.edu/usdoepub/32","host_type":"repository"}],"fields_of_study":["Carbon Nanotubes in Composites","Porphyrin and Phthalocyanine Chemistry","Molecular Junctions and Nanostructures"],"mesh_terms":[],"keywords":["Porphyrin","Chemistry","Carbon nanotube","Photoinduced electron transfer","Photochemistry","Quenching (fluorescence)","Covalent bond","Electron transfer","Protonation","Electron acceptor","Free base","Thermogravimetric analysis","Selective chemistry of single-walled nanotubes","Fluorescence","Nanotechnology","Organic chemistry","Optical properties of carbon nanotubes","Nanotube","Materials science"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-13T18:42:42.562184Z","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":[]}
