3,6-Dibromocarbazole was identified to be triboluminescent for the first time. From the triboluminescence and photoluminescence spectra, it was found that the room-temperature triboluminescence spectrum of 3,6-dibromocarbazole, unlike most other triboluminescent materials, was different from its photoluminescence spectrum at the same temperature and was composed of a weak tribofluorescence and a strong tribophosphorescence. This result can be ascribed partly to the "heavy atom effect" caused by the two bromine substituents and partly to the change in luminescence quantum yields experienced during the breakage of the crystals. Its symmetry of crystalline structure was determined to belong to the acentric space group using the method of second-harmonic generation.
