ABSTRACT
In recent years, there is a burgeoning interest in using entropy and principles of geometry to guide the assembly of molecular assemblies. The entropy and geometry can be powerful tools to organize molecular assemblies into specific structures or morphologies. Pusey and coworkers prepared binary microparticle superlattices from the entropy driven self-assembly of polymethylmethacrylate (PMMA) microparticles. They used microparticles of hundreds of nanometers to prepare binary microparticle superlattices. The nanoparticles properties can be tuned during synthesis and by controlling the assembly of these modular nanoparticles into ordered mesoscale superlattices; it then gives the opportunity to control the bulk materials properties. Venkataraman and coworkers preformed the electron donor and electron acceptor as spherical nanoparticles and then assembled these nanoparticles to form the device active layer in an organic photovoltaic (OPV) device. Controlling the morphology of the active layer in OPVs has a direct impact on the device's efficiency.
