Height dependent molecular trapping in stacked cyclic porphyrin nanorings
Wieland, Maria B. and Perdigão, Luis M.A. and Kondratuk, Dmitry V. and O'Shea, James N. and Anderson, Harry L. and Beton, Peter H. (2014) Height dependent molecular trapping in stacked cyclic porphyrin nanorings. Chemical Communications, 55 . pp. 7332-7335. ISSN 1364-548X
Stacked layers of cyclic porphyrin nanorings constitute nanoscale receptacles with variable height and diameter which preferentially adsorb sublimed molecules. Using scanning tunnelling microscopy we determine the filling capacity of these nanoring traps, and the dependence of adsorbate capture on stack height and diameter.
