Buckybowls on Metal Surfaces:Symmetry Mismatch and Enantio-morphism of Corannulene on Cu(110)

摘要

Functionalization of surfaces by adsorption of aromatic organic molecules is an important approach towards new materials for photovoltaics,organic light-emitting devices(OLEDs),and molecular electronics such as organic field effect transistors(OFETs).The structure of the monolayer,in turn,affects the electronic and optical properties of thin films.A periodic two-dimensional(2D)supramolecular surface exhibits a restricted set of lattice symmetries,and thus not all molecular point group symmetries can be maintained exclusively in a tiling array.
