Electron-deficient (dibenzoylmethanato)boron difluoride (DBMBF2) can efficiently discriminate between electron-rich polynuclear aromatic hydrocarbons like naphthalene (A1), anthracene (A2) or phenanthrene (A3). Even using the same sort of electron donor–acceptor (EDA) interaction, DBMBF2, can recognise different polar polynuclear aromatic systems containing indeno-pyridine groups (I1–I3). EDA Interaction...
Absorption and emission spectroscopic studies of (dibenzoylmethanato)boron difluoride (1bf) in various polar and non-polar, protic and aprotic solvents are reported. The solvatochromic shifts of the spectral bands were examined in terms of solvent properties, including donor and acceptor numbers, followed by multilinear regression in which several solvent parameters were simultaneously analyzed. This...
