Abstract

The first cycloparaphenylene (CPP)-based ionic donor-acceptor supramolecule Li+@C60⊂[10]CPP X- has been synthesized. X-ray crystallography not only confirmed the molecular structure of Li+@C60⊂[10]CPP X- but also uncovered the formation of a unique ionic crystal. The strong charge-transfer interaction between [10]CPP and Li+@C60, which was confirmed by electrochemical measurement and spectroscopic analyses, caused significant delocalization of the positive charge across the entire complex. Widen your sphere of influence: A strong charge-transfer interaction between [10]CPP and Li+@C60 in the first cycloparaphenylene (CPP)-based ionic donor-acceptor supramolecule Li+@C60⊂[10]CPP X- is confirmed by electrochemical measurement and spectroscopic analyses. The complex is also characterized by X-ray crystallography. The charge transfer causes significant delocalization of the Li+ positive charge over the entire complex.
