چکیده
Cyclobis(paraquat-p-phenylene)s complexed with anionic surfactants exhibit liquid-crystalline states and form pseudorotaxanes with tetrathiafulvalene in the condensed states.

Anion effects on the cyclobis(paraquat-p-phenylene) host.
Binding studies between the electron accepting host cyclobis(paraquat-p-phenylene) and a series of electron donors in the presence of differently sized counteranions reveal that both the nature and the concentration of the anion have a large impact on the association strength of the resulting host-guest complex.
متن کاملComplexation between pentiptycene-based mono(crown ether)s and tetracationic cyclobis(paraquat-p-phenylene): who is the host or the guest?
Pentiptycene-based mono(crown ether)s and tetracationic cyclobis(paraquat-p-phenylene) can form 1 : 1 stable complexes in solution and in the solid state, in which both of the components act as the host as well as the guest.
متن کاملA pentiptycene-based bis(crown ether) host: synthesis and its complexation with cyclobis(paraquat-p-phenylene).
A novel pentiptycene-based bis(crown ether) host incorporating two dibenzo-24-crown-8 ether moieties has been synthesized, and its efficient complexation ability toward cyclobis(paraquat-p-phenylene) in solution and in the solid state has been explored.
متن کاملSelf-assembly in chemical systems
The development of a simple approach to studying self-assembly processes in the chemical laboratory began with an investigation of the donor/acceptor complexes formed between (a) crown ethers, like bisparaphenylene-34crown10, and 4,4 '-bipyridinium dications, such as paraquat, and (b) tetracationic cyclophanes, like cyclobis(paraquat-p-phenylene), and neutral substrates, such as 1.4dimethoxyben...
متن کاملA semiconducting organic radical cationic host-guest complex.
The self-assembly and solid-state semiconducting properties of single crystals of a trisradical tricationic complex composed of the diradical dicationic cyclobis(paraquat-p-phenylene) (CBPQT(2(•+))) ring and methyl viologen radical cation (MV(•+)) are reported. An organic field effect transistor incorporating single crystals of the CBPQT(2(•+))⊂MV(•+) complex was constructed using lithographic ...
