The intriguing and rich photophysical properties of three curved nanographenes (CNG), each containing a corannulene (Cor) and a tert-butylhexa-peri-hexabenzocoronene (HBC-tBu) fragment, have been investigated as a function of their structural design (loose-helicene, CNG 6; cycloheptatrienically constrained helicene, CNG 8; cycloheptatrienically plus sterically constrained helicene, CNG 7). All CNG exhibit narrow fluorescence in the visible range (50
