abstract = {Water-soluble shape-persistent cyclodextrin (CD) polymers
with amino-functionalized end groups were prepared starting
from diacetylene-modified cyclodextrin monomers by a
combined Glaser coupling/click chemistry approach.
Structural perfection of the neutral CD polymers and
inclusion complex formation with ditopic and monotopic guest
molecules were proven by MALDI–TOF and UV–vis
measurements. Small-angle neutron and X-ray (SANS/SAXS)
scattering experiments confirm the stiffness of the polymer
chains with an apparent contour length of about 130 Å.
Surface modification of planar silicon wafers as well as AFM
tips was realized by covalent bound formation between the
terminal amino groups of the CD polymer and a reactive
isothiocyanate–silane monolayer. Atomic force measurements
of CD polymer decorated surfaces show enhanced
supramolecular interaction energies which can be attributed
to multiple inclusion complexes based on the rigidity of the
polymer backbone and the regular configuration of the CD
moieties. Depending on the geometrical configuration of
attachment anisotropic adhesion characteristics of the
polymer system can be distinguished between a peeling and a
shearing mechanism.},
