Abstract

The conformations of tetracationic paracyclophane and metacyclophane derivatives containing quaternary salts of para-2, 2-diazaterphenyl were investigated. The molecules were synthesized as the bromide and hexafluorophosphate salts which allowed solubility in aqueous and organic solvents. Molecular mechanics led to the notion that these cyclophanes would populate collapsed and open conformations in water and only ...
