Binding and photophysical studies were performed in two solvents of very different polarity: toluene and dichloromethane. UV\/Vis and fluorescence titration experiments showed \u03c0\u2013\u03c0 interactions between the cyclic zinc bisporphyrins and the fullerenes. Solid\u2010state structures were determined by X\u2010ray diffraction analysis and gave valuable insight into the different complexation behaviors of the two macrocyclic systems towards the fullerenes. NMR titrations were also helpful in understanding the geometry of the complexes in solution. Upon fullerene complexation, the two macrocyclic bisporphyrins adopt very distinct conformations. Charge\u2010transfer absorption bands point to ground\u2010state interactions, and quenching of the porphyrin component luminescence indicates fast reactivity in the excited states. Energy transfer plus HOMO\u2013HOMO and LUMO\u2013LUMO electron\u2010transfer processes occur within the complexes. Charge\u2010separated states characterized by a reduced fullerene and an oxidized porphyrin radical, with lifetimes in the order of several hundred picoseconds, are detected.<\/jats:p>","DOI":"10.1002\/chem.201101511","type":"journal-article","created":{"date-parts":[[2011,11,17]],"date-time":"2011-11-17T10:44:32Z","timestamp":1321526672000},"page":"14564-14577","source":"Crossref","is-referenced-by-count":31,"title":["Supramolecular Inclusion Complexes of Two Cyclic Zinc Bisporphyrins with C<sub>60<\/sub> and C<sub>70<\/sub>: Structural, Thermodynamic, and Photophysical Characterization"],"prefix":"10.1002","volume":"17","author":[{"given":"Laura P.","family":"Hern\u00e1ndez\u2010Egu\u00eda","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eduardo C.","family":"Escudero\u2010Ad\u00e1n","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Inmaculada C.","family":"Pintre","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Barbara","family":"Ventura","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lucia","family":"Flamigni","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pablo","family":"Ballester","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2011,11,17]]},"reference":[{"key":"e_1_2_6_1_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ccr.2010.05.006"},{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1021\/cr0000426"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1002\/ange.200301665"},{"key":"e_1_2_6_3_3","doi-asserted-by":"publisher","DOI":"10.1002\/anie.200301665"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tet.2004.10.073"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1007\/430_018"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja992165h"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1039\/B614883M"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1021\/ar040168f"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1039\/b905753f"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1002\/chem.201001815"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1021\/jp9076849"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1002\/1521-3757(20010202)113:3<502::AID-ANGE502>3.0.CO;2-A"},{"key":"e_1_2_6_12_3","doi-asserted-by":"publisher","DOI":"10.1002\/1521-3773(20010202)40:3<486::AID-ANIE486>3.0.CO;2-P"},{"key":"e_1_2_6_13_2","doi-asserted-by":"publisher","DOI":"10.1002\/ange.200200561"},{"key":"e_1_2_6_13_3","doi-asserted-by":"publisher","DOI":"10.1002\/anie.200200561"},{"key":"e_1_2_6_14_2","doi-asserted-by":"publisher","DOI":"10.1002\/1521-3757(20010518)113:10<1909::AID-ANGE1909>3.0.CO;2-S"},{"key":"e_1_2_6_14_3","doi-asserted-by":"publisher","DOI":"10.1002\/1521-3773(20010518)40:10<1857::AID-ANIE1857>3.0.CO;2-Y"},{"key":"e_1_2_6_15_2","doi-asserted-by":"publisher","DOI":"10.1002\/ange.200704058"},{"key":"e_1_2_6_15_3","doi-asserted-by":"publisher","DOI":"10.1002\/anie.200704058"},{"key":"e_1_2_6_16_2","doi-asserted-by":"publisher","DOI":"10.1021\/ol101393h"},{"key":"e_1_2_6_17_2","doi-asserted-by":"publisher","DOI":"10.1002\/ange.19860981202"},{"key":"e_1_2_6_17_3","doi-asserted-by":"publisher","DOI":"10.1002\/anie.198610393"},{"key":"e_1_2_6_18_2","doi-asserted-by":"publisher","DOI":"10.1039\/b413971b"},{"key":"e_1_2_6_19_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja0747526"},{"key":"e_1_2_6_20_2","doi-asserted-by":"publisher","DOI":"10.1021\/jo200154d"},{"key":"e_1_2_6_21_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja992416m"},{"key":"e_1_2_6_22_2","doi-asserted-by":"publisher","DOI":"10.1023\/A:1014424103925"},{"key":"e_1_2_6_23_2","doi-asserted-by":"publisher","DOI":"10.1021\/cr100072x"},{"key":"e_1_2_6_24_2","doi-asserted-by":"publisher","DOI":"10.1039\/p19950002247"},{"key":"e_1_2_6_25_2","doi-asserted-by":"publisher","DOI":"10.1021\/jo982452o"},{"key":"e_1_2_6_26_2","first-page":"2038","volume":"29","author":"Golubchikov O.
