Ki. Chane-ching et al., Electropolymerization of hydrophobic dipyrrolyls in aqueous medium based on inclusion chemistry, J MAT CHEM, 9(5), 1999, pp. 1065-1070
The host-guest complexation of hydrophobic dipyrrolyl monomers 1-4 with bet
a-cyclodextrin has been studied in aqueous solution by means of H-1 NMR spe
ctroscopy, chemical analysis and electrochemical techniques. In each case,
1:2 stoichiometry is found, the cyclodextrin cavities being likely located
on the extremities of the monomers. Polymeric materials were obtained from
such inclusion compounds in water by either electrochemical or chemical oxi
dation. ESCA and elemental analyses show that the host molecule is absent f
rom these polymers,whose characteristics are quite similar to those synthes
ized in organic media. A scheme for polymerization in the presence of cyclo
dextrin is proposed.
