Abstract

The design of easily modifiable nanohoops with favourable photophysical properties is crucial for their applications. Here, carborane-based boron-clusters are linked to meta-cycloparaphenylenes (mCPPs) as pendants through an alkyne insertion reaction with decaborane from an mCPP-alkyne precursor. Subsequent deboronation reaction efficiently yields ionic mCPP compounds with a high fluorescence quantum yield (81%) in solution.
