The anions went in two by two: Separate ion-pair binding of nano-sized α,ω-alkanediyldiammonium dichloride salts is achieved in organic media with high efficiency and selectivity by a heterotetratopic receptor that comprises two converging calix[5]arene units to tightly encapsulate the linear dication, as well as two ureido side functions to simultaneously bind the chloride counteranions through hydrogen bonding (see picture).

Abstract
The anions went in two by two: Separate ion-pair binding of nano-sized α,ω-alkanediyldiammonium dichloride salts is achieved in organic media with high efficiency and selectivity by a heterotetratopic receptor that comprises two converging calix[5]arene units to tightly encapsulate the linear dication, as well as two ureido side functions to simultaneously bind the chloride counteranions through hydrogen bonding (see picture).File in questo prodotto:
