“…The UV–vis absorption, fluorescence emission and fluorescence lifetime spectra in water of the studied molecules are shown in Figure 4 . As shown in Figure 4 A, in aqueous conditions (neutral water), Cur exhibited a broad absorption band at around 427 nm with a shoulder at ∼350 nm, which arise assigned to the π−π* transitions associated with the conjugated Cur and the feruloyl unit, respectively [ 28 , 29 ].…”

“…By covalent binding of Cur to β-CD molecules, two important changes in the UV–vis absorption spectra of Cur were observed. First, a hyperchromic effect was observed in the UV–vis spectra of both nanoconjugates in D 2 O, where the absorption intensity of Cur in water increased significantly depending on the number of β-CD molecules coupled to Cur ( Figure 4 A), indicating an increase in the solubilization of Cur inside the nanoconjugates [ 28 , 29 , 30 ]. Second, the broad absorption band at 427 nm became narrower in the case of both nanoconjugates and a significant blue shift to 365 nm occurred in the case of the nanoconjugate 5 ( Figure 4 A).…”

“…Em meio aquoso, a CUR também pode existir em equilíbrio entre ambas as formas ceto e enólica (PRIYADARSINI, 2014), sendo a forma ceto predominante em solução ácida/neutra e a forma enol em meio alcalino (GONÇALVES et al, 2017).…”

“…Resultados semelhantes foram obtidos em estudos envolvendo CUR e argilas realizados neste grupo de Fotoquímica. A estabilidade da curcumina foi aumentada em presença de argilas (sistemas CUR/laponita e CUR/SWy-2) quando comparado com soluções aquosas (GONÇALVES et al, 2017). A argila laponita apresentou os melhores resultados de estabilidade devido à sua maior capacidade de esfoliação.…”
