Molecular Self-Assembly

halbondsTIBTAlmost all the new technologies are intrinsically linked to the application of new materials. The capture of solar energy and nanoelectronics are two emerging areas where progress depends almost exclusively on the development of new, more advanced materials. In this regard, the two-dimensional materials, especially graphene, have received considerable attention due to their superior electronic properties and their ability to produce devices from a small amount (a single-atom-thick layer) of material. A major obstacle to the replacement of silicon in general graphene in transistors and other electronic devices, is related to the fact that it has no bandgap therefore can not be “switched off”.

To overcome this limitation, we consider the synthesis of materials topologically similar to graphene from molecular components (building blocks), by self-assembly and polymerization directly on a supporting surface. The surface polymerization of multidentate monomers can lead to the formation of two-dimensional structures related to the topology of graphene, with potentially exceptional electronic and optoelectronic properties. Novel molecules and geometries are subsequently deployed to device substrates to build and test prototype FETs, OLEDs, OFETS, or sensors.
