Abstract
Herein we report the construction of an inherently chiral carbon nanoring, cyclo[7]paraphenylene-2,9-rubicene ( [7]CPPRu 2,9 ), by combining rubicene with a C-shaped synthon through the Suzuki–Miyaura coupling reaction. The structure was fully confirmed by high-resolution mass spectroscopies (HR-MS) and various NMR techniques. The photophysical properties were investigated by UV–vis absorption and fluorescence spectroscopy as well as the time-resolved fluorescence decay. Moreover, two enantiomers ( M )/( P ) - [7]CPPRu 2,9 were successfully resolved by recyclable HPLC and studied by CD and CPL spectra.
