Host-guest complexation: A strategy to form sexithiophene exhibiting self-assembly properties

Communication: A new route for the electrosynthesis of sexithiophene (6T) f ilms with well-ordered structure is described. Applications of oligothiophe nes in organic electronic devices-to which 6T is well suited owing to its a ttractive charge-transport properties-necessitate a well-defined structural order. The formation of an inclusion complex of terthiophene (3T) in the h ost hydroxypropyl-P-cyclodextrin in an aqueous medium is demonstrated and a lso that the subsequent electropolymerization leads essentially to 6T. It i s shown that use of the P-cyclodextrin induces an ordering effect.
