Graphene,1,2 a two-dimensional(2D) material,has drawn world-wide attention and demonstrated extraordinary promise in nanoelectronics,optical limiters,biosensors,supercapacitors,and polymer nanocomposites due to its exceptional electronic,thermal,optical,and mechanical properties.3-6 Since the unusual phenomenon of aggregation induced emission(AIE),studies on tetraphenylethylenes(TPEs) have become more and more intense owing to its great simplicity in synthesis and derivatization.
