Intra and intermolecular interactions of OeninCoum were characterized by UV–vis absorption, 1H NMR and circular dichroism (CD). Theoretical calculations were also performed to describe the intramolecular interactions. At higher temperature (>60 °C) the intermolecular aggregates are disrupted but CD signal attributed to an intramolecular interaction remains. Moreover, the kinetic and thermodynamic data for Oenin and OeninCoum at 50 °C and 25 °C shows that the increase of temperature stabilizes the quinoidal base of this later.LAQV@REQUIMTEDQ - Departamento de QuímicaRUNMendoza, JohanOliveira, JoanaAraújo, PaulaBasílio, NunoTeixeira, NatérciaBrás, Natércia F.Pina, FernandoYoshida, Kumide Freitas, Victor2022-03-07T01:31:06Z2020-092020-09-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10362/113065eng0143-7208PURE: 17903237https://doi.org/10.1016/j.dyepig.2020.108382info:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-03-11T04:56:18Zoai:run.unl.pt:10362/113065Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T03:42:15.788436Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
