Novel carbazole-based aggregation-induced emission-active gold(I) complexes with various mechanofluorochromic behaviors

Carbazole-based gold(I) complexes 1-6 all showed excellent AIE properties. In addition, luminogens 1 and 2 show reversible mechanochromism characteristics. Luminogens 3 and 4 exhibit switchable mechanochromic luminescence behaviors. Irreversible mechanofluorochromic phenomena were observed for luminogens 5 and 6.189
