The luminescence property of the AIEgens (AIE=aggregation induced emission luminogens) depends on the modification of conformational and intermolecular interactions in contrast to the classical organic luminophores. The temperature-dependent emission spectra of 7 was measured with an excitation wavelength of 365 nm. The emission maximum around 483 nm shows a decrease in intensity while heating from 130 K, reaching the minimum at 290 K. Afterwards, the PL intensity starts to increase, and a notable abrupt increase is observed between 330 and 380 K, reaching the maximum at 380 K close to the temperature where SCO is completed (Fig. ).
