Solid-state organic fluorescent materials are important for the development of electroluminescent sensing devices. Herein, we report that N , N' -bis(( R )-1-phenylethyl)perylene-3,4,9,10-tetracarboxylic diimide [( R , R )-BPP] and its antipode [( S , S )-BPP], which contain extended π-electrons through planar perylenes, emit solid-state aggregation-induced-enhanced (AIEnh) circularly polarised luminescence (CPL) in inorganic (KBr) pellets and organic-polymer-film (PMMA- and myo -IPU-film) states; this CPL is difficult to observe in solution. These chiral perylene fluorophores emit AIEnh-CPL with high dissymmetry factors ( g  CPL ) (up to 2.4 × 10 -3 ) and high quantum yields ( Φ  F , up to 0.43) in the three solid matrices.
