METHOD FOR GENERATING SUPRAMOLECULAR ROTARY DEVICES AND SUPRAMOLECULAR ROTARY SWITCH

摘要

A method for generating a porous network of supra-molecular devices includes the steps of: a) providing self-organizing molecules comprising connecting bonds and side-groups; b) generating a two-dimensional layer of the molecules on an unstructured surface, wherein self-organizing leads to an at least partially regular network of cells, each cell comprising a number of said self-organizing molecules and each cell offering a functional center; and c) further depositing a predefined amount of said self-organizing molecules and/or of other functional molecules on said two-dimensional layer, wherein these further deposited molecules accommodating in said functional centers of said cells, one or more of said further deposited molecules per cell, wherein said further deposited molecule comprises a multi-stable architecture together with the cell hosting the further deposited molecule. This method provides a rotary switch that offers on a large scale a bottom-up self assembly of the self-organizing molecules that result in a nanoporous network with single supra-molecular switches that can be addressed individually and switched by changing its orientation. Such rotary switch is at low cost a very flexible and powerful nanodevice that can be largely used in molecular electronic applications, such as for the purpose of storing information.
