Cyclobis(paraquat-p-phenylene) is able to incorporate small guest molecules forming a host–guest complex. The interactions required for complex formation are donor-acceptor interactions and hydrogen bonding, their strength is highly dependent on the ability of the donor to provide π-electron density. Also an enlargement of the π-system ...
