New synthesis of multi-layer 3 D chiral molecules has been developed under novel conditions to give better *** aggregation-induced emission(AIE),UV irradiation/excitation,charge transfer(CT)and local excited(LE)ππ*transitions have been investigated on a representative individual enantiomer of pseudo C_2 asymmetry which was made possibly by differentiating moieties on phosphorous on N-phosphonyl ring of chiral sandwich ***,a new tandem C–N/C–C coupling reaction was unexpectedly rendered providing a novel access to special benzo[a]carbazoles.
