Intramolecular coupling of extended biphen[n]arenes is developed to yield cycloparaphenylenes (CPPs). The modular nature of biphen[n]arenes makes it possible to customize CPP structures, which permits tuning of their photophysical properties. The syntheses are short and excellent yields are achieved. Moreover, postsynthetic functionalization is possible.
