A porphyrin nanochannel:formation of cationic channels by a protonated saddle-distorted porphyrin and its inclusion behavior

摘要

A highly saddle-distorted dodecaphenylporphyrin dication (H_4DPP~(2+)) was revealed by X-ray crystallography to form positively charged porphyrin nanochannels which were 1 nm in diameter;chloride anion and redox-active hydroquinone could be incorporated in the channels.
