Abstract
In this work, two-photon induced excimer up-conversion emission of dicyanoisophorone derivative (1) in crystal state is described. 1 shows crystal emission, with one-photon excitation both monomer and excimer emission are detected. An enhanced excimer emission of 1 in crystal state has been observed with a 800Â nm Ti-sapphire femtosecond pulse laser, mechanism reveals that the enhanced excimer emission may result from the two-photon absorption. X-ray single crystal analysis demonstrates that the molecules of 1 adopt a face-to-face offset stacking mode in crystals, which benefits the excimers formation and emission.
