Using the building block strategy for [n]CPPs, different nitrile substituted meta[n]CPPs (n=6, 8, 10) have been prepared. The nitrile substituent offers a convenient handle for functional group conversions (e.g., carboxylic acid, amide, aldehyde, as well as 1H-tetrazole). Besides the synthetic work, the photophysical properties of these novel m[n]CPP derivatives have been characterized. Additionally, the host–guest ability of cyano-m[10]CPP has been explored by studying its complexation with fullerene C60. These insights open new applications of meta[n]CPPs as fluorophore in synthetic organic chemistry, material sciences as well as biomedical research.enNamensnennung - Nicht kommerziell 4.0 InternationalMacrocyclesHydrocarbonsFluorescenceHost-guest systemsSolid-state structuresddc:540
