摘要: Nanosecond time‐resolved emission spectral techniques have been applied to the problem of origin and nature well‐known temperature‐dependent shifts characteristic aminophthalimides in alcohol solvents. It is demonstrated that are fact due time‐dependent shifts. At least two relaxation times characterize this phenomenon. One time observed be subnanosecond character may associated with exciplex presumably present system. The other nonspecific dipolar reorientation although it has distinctly different characteristics from solvent dielectric time. Wavelength‐dependent fluorescence decay can explained by dependence spectrum also observed.
