Influence of interfacial features in the supramolecular assembly of 3,5-dihydroxybenzylalcohol based dendrimers on Si/SiO_2 surfaces

摘要

Self-organization of 3,5-dihydroxybenzylalcohol (DHBA)based dendrimers of generations0-3 (G0-G3)on bare and functionalized single crystal silicon (Si/SiO_2)surfaces has been examined.The underlying monolayer plays a significant role in the supramolecular assembly leading to ordered structures of DHBA (GO)and generation 1-3 (G1-G3)dendrimers at interfaces.Ordered hyperbranched structures are formed on surfaces containing self-assembled monolayers with complimentary features to the assembling molecules,whereas no such organized assemblies are observed on unfunctionalized surfaces.
