2 The molecule depicted is currently under scrutiny for its potential in generating blue emission
for OLED applications. The molecule's emission at 470 nm in ethanol is displayed below.
470 nm emission
NC.
CN
OCH 3
| 470 nm emission
a. Employ a potential energy surface to elucidate the phenomenon of dual fluorescence (at
Amax = 350 and 470 nm) observed upon excitation of this molecule.
b. In polar solvents, the fluorescence intensity of the longer wavelength species (350 nm)
experiences a significant boost. Conversely, in non-polar solvents like benzene, a more
widespread occurrence of dual fluorescence is noted. Elaborate on this observation.
