Odd–even effect in two dimensions induced by the bicomponent blends of isobutenyl compounds

Author affiliations

Abstract

Scanning tunneling microscopy (STM) investigation was performed for the blends of isobutenyl compounds, in which the long alkyl chains were connected with ester or carbamoyl linkages. Each component by itself did not show the odd–even effect of alkyl chain length, whereas after blending them, the 2D structures drastically changed and modulated to exhibit odd–even effect. Star, lozenge, twist-like, and linear structures were found, dependent on the blend ratio and alkyl chain length. The blend ratio dependence of 2D structures was explained in terms of homogeneous and heterogeneous dimerization due to the interdigitation of alkyl chains.
