We report the facile synthesis of two novel carbon nanorings based on N-annulated perylene (NP-[n]CPP, n = 9,10) by Pd-catalyzed Suzuki coupling and a subsequent reductive aromatization reaction. Their photophysical properties were investigated by steady-state and time-resolved spectroscopies. Conjugated NP-[n]CPP nanorings showed a significant redshift (90 nm for emission) compared to the N-annulated perylene unit. In addition, the supramolecular interaction behavior between NP-[10]CPP and fullerene C60 were also studied, and the binding constant was determined to be 1.18 × 105 M-1. Furthermore, the potential application of NP-[9]CPP and NP-[10]CPP in organic field-effect transistors (OFETs) was investigated, their carrier mobilities were 2.0 × 10-5 cm2 V-1 s-1 and 3.4 × 10-5 cm2 V-1 s-1, respectively.
