In conclusion, we designed and synthesized cyclophane-type dications 2a 2+ -2c 2+ , composed of two units of planar -units xanthylium 1 + with the alkylene linkers. X-ray analyses of dication salts 2a 2+ (BF 4 -) 2 -2c 2+ (BF 4 -) 2 showed that the cation units are closely stacked and facing each other in the crystal due to the non-covalent interaction between planar -units, which was demonstrated by NCI plots.
