The new scaffold demonstrates efficient intramolecular through-space charge transfer, with electron-rich benzofuran and electron-deficient ynone groups strategically placed in proximity via a naphthalene spacer. The charge transfer is supported by distinct CT bands in the visible region (>500 nm) in their UV-vis absorption and emission spectra.
We have developed a new scaffold that exhibits an efficient intramolecular through-space charge transfer (CT). In this design, electron-rich benzofuran and electron-deficient ynone groups are placed strategically in proximity via a naphthalene spacer. Charge transfer is supported by distinct CT bands in the visible region (>500 nm) in their UV-vis absorption and emission spectra.
