Herein, we report the synthesis of semi-coronenediimide (sCDI) and N-caprolactam pyrrolo-perylenediimide (pPDI) using l,8-diazabicyclo[5,4,0]undec-7-ene (DSU). The reaction involves in situ removal of trimethylsilyl (TMS) group followed by a ring formation at the ortho and bay positions of perylenediimide (PDI). Both the molecules exhibit diverse photophysical properties. pPDI demonstrates panchromatic absorption with quenched fluorescence while sCDI displays blue-shifted absorption with high fluorescence quantum yield. The obtained sCDI has been structurally characterized.
