The dye was fully characterized by LC-DAD\/ESI-MS and NMR 1D and 2D techniques, and a formation pathway was proposed. The novel dye obtained revealed extended \u03c0-conjugation (\u03bbmax 556 nm) and catechol groups in its composition, which is very important for applications as a photosensitizer for dye-sensitive solar cells (DSSCs).<\/jats:p>","DOI":"10.1055\/s-0036-1591978","type":"journal-article","created":{"date-parts":[[2018,4,11]],"date-time":"2018-04-11T18:54:41Z","timestamp":1523472881000},"page":"1390-1394","source":"Crossref","is-referenced-by-count":10,"title":["Synthesis and Structural Characterization of a Novel Symmetrical 2,10-Bis-Styryl-1-Benzopyrylium Dye"],"prefix":"10.1055","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2226-0404","authenticated-orcid":false,"given":"Lu\u00eds","family":"Cruz","sequence":"first","affiliation":[{"name":"REQUIMTE\/LAQV, Department of Chemistry and Biochemistry, Faculty of Sciences, University of Porto"}]},{"given":"V\u00e2nia","family":"Gomes","sequence":"additional","affiliation":[{"name":"REQUIMTE\/LAQV, Department of Chemistry and Biochemistry, Faculty of Sciences, University of Porto"}]},{"given":"Nuno","family":"Mateus","sequence":"additional","affiliation":[{"name":"REQUIMTE\/LAQV, Department of Chemistry and Biochemistry, Faculty of Sciences, University of Porto"}]},{"given":"Victor","family":"de Freitas","sequence":"additional","affiliation":[{"name":"REQUIMTE\/LAQV, Department of Chemistry and Biochemistry, Faculty of Sciences, University of Porto"}]}],"member":"194","published-online":{"date-parts":[[2018,4,11]]},"container-title":["Synlett"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/s-0036-1591978.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2018,5,30]],"date-time":"2018-05-30T18:45:49Z","timestamp":1527705949000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/s-0036-1591978"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,4,11]]},"references-count":0,"journal-issue":{"issue":"10","published-online":{"date-parts":[[2018,5,30]]},"published-print":{"date-parts":[[2018,6]]}},"URL":"https:\/\/doi.org\/10.1055\/s-0036-1591978","relation":{},"ISSN":["0936-5214","1437-2096"],"issn-type":[{"value":"0936-5214","type":"print"},{"value":"1437-2096","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,4,11]]}}}
