A molecular tube (MT) is a tubular macromolecule formed by the one-dimensional linkage of alpha-cyclodextrins and exhibits molecular recognition for selecting the diameter of a polymer chain. In this letter, we immobilized MTs on a self-assembled monolayers (SAM) of inclusion complexes (DDT-CD) between dodecanethiol (DDT) and beta-cyclodextrin (beta-CD). The DDT-CD inclusion complexes formed uniform self-assembled monolayers on gold. We confirmed that the MTs were immobilized on the DDT-CD SAM using dynamic contact angle measurements, surface-plasmon resonance (SPR), and scanning probe microscopy (SPM).
