英文摘要	In pursuit of design and modification of photophysical properties on molecular level, N,N'-disubstituted-dihydrodibenzo[a,c]phenazines were demonstrated as a vivid example of elaborate manipulation via 'vibration induced emission' (VIE), which is coined for this particular change in configuration and planarity motion. Significant alternation was observed upon environmental change in polarity, viscosity and temperature, including dual fluorescence and large Stokes shift, etc. In-depth investigations were utilized such as temperature dependent steady-state spectroscopy, nanosecond time-resolved spectroscopy, femtosecond dynamics and computational simulation of the reaction energy surfaces, which manifest this phenomenon as a novel mechanism attributed to intrinsic switch-ability of these molecules. In light of this case, the concept of VIE can be introduced as a universal criteria for facile control of the photophysical pattern and hopefully be extended to versatile applications in photoelectric and biomedical disciplines.; CPCI-S(ISTP); 21-33; 1226
