摘要: Abstract N,N′-Dimethyl-2,7-diazapyrenium bis(hexafluorophosphate) binds a C3-symmetric bis(m-phenylene)-32-crown-10-based cryptand more strongly than N,N′-dimethyl-4,4′-bipyridinium partly because of its better fit in size with the host cavity, while it relatively smaller pyridyl less due to worse cavity and lack hydrogen bonding nitrogen atom host.
