Janus discs: preparation, size-tunability, visualization, self-assembly

Abstract

In recent years, Janus particles have attracted much attention in nanoscience due to their interesting properties, both for academic as well as for technological reasons. In general, Janus structures have a compartmentalized surface and can be divided into three classes according to their architecture – spherical Janus micelles (3D)1, 2, two types of Janus cylinders (1D)3 and Janus sheets or discs (2D), representing the intermediate case of dimensionality (see scheme 1). The synthesis of such non-centrosymmetric structures with compartmentalized coronas is a demanding task for the synthetic chemist. Hence, only a few real nanosized polymer-based Janus structures are known in literature.
