AI Article Synopsis
- The study examines how two flavone derivatives, 3-hydroxyflavone and 4'-N,N-diethylaminoflavonol, behave in excited states when placed in a confined medium.
- It suggests that supramolecular interactions can significantly change the fluorescence characteristics of these compounds.
- In the specific environment of an octa acid host, both dyes exhibit a unique large Stokes shift in their emission due to proton transfer within the molecules, contrasting with their behavior in water.
Article Abstract
The excited state behavior of two flavone derivatives 3-hydroxyflavone and 4'-N,N-diethylaminoflavonol in a confined medium indicates that supramolecular effects could alter the nature of the fluorescence emission. Within the octa acid host the neutral unionized species of these two dyes are present showing large Stokes shifted emission due to intramolecular proton transfer, a pattern different from that in aqueous medium.
