, p. 925 - 929 (2010)
UV absorption spectra of 1,3-diphenylpropane-1,3-dione (1), its three methoxy derivatives (2-4) and its six dimethoxy derivatives (5-10) in various solvents dissolved were collected. The keto-enol tautomerism equilibrium constant was calculated with 1H NMR. The position of the methoxy group in 1,3-diphenylpropane-1,3-dione was shown to have an influence on the molecule's UV absorption spectrum and the keto-enol tautomerism equilibrium constant. The methoxy group in the para position increases the absorption of radiation in the UV-A range. A shift to the keto form in the keto-enol tautomerism equilibrium is experienced by compounds with methoxy groups in ortho position. When two methoxy groups are present, the influence of their position is cumulative.

Purely organic phosphors have important applications in imaging, sensing, informatics and illumination. Methoxy-substituted difluoroboron dibenzoylmethane (BF2dbm) complexes exhibit intense fluorescence with an almost unity quantum yield. Here
Influence of the Localization of the Excitation Energy on the Photochemistry of α,β-Epoxy Ketones
Hallet, Philippe,Muzart, Jacques,Pete, Jean-Piere
, p. 4275 - 4279 (2007/10/02)
Depending on the localization of the energy, photolysis of α-epoxy ketones excited in their triplet state leads to β-diketones, α-diketones, or fragmentation products.Absorption spectra of ylide intermediates and phosphorescence spectra of α-epoxy ketones are reported.
