In order to obtain monolayers of wholly π-conjugated derivatives with improved stability and homogeneity, oligo(phenylenevinylene derivatives with different numbers of phenylenevinylene units, different hydrophilic groups and different substituents at the end of the hydrophobic π-conjugated chain were synthesized and their surface pressure-area isotherms and fluorescence microscopy images were examined. The presence of two phenylenevinylene units was suitable for monolayer formation. Monolayers with improved stability were obtainable from sulfonamide derivatives with a tert-butyl or an octadecyl group at the hydrophobic ends and from a derivative which had a sulfonamide group between the π-conjugated structure and an alkyl spacer group Fluorescence microscopy revealed that the tert-butyl derivative formed a homogeneous monolayer in the condensed region. The effects of the substituents upon the monolayer properties were discussed.
