Welcome to USTALAB Research where we master chemistry to engineer modern functional materials for (opto)electronics and nanotechnology

Organic materials have long been considered as efficient electrical insulators due to their poor electronic properties. Until very recently, they have been mostly utilized in non-electronic applications such as packaging, textile, and manufacturing as a natural outcome of their advantageous synthesis with unprecedented structural versatility and advantageous mechanical-physical properties over inorganics, metals, and ceramics. Today, It is almost impossible to find an aspect of our lives that is not affected by organics. The idea of using organic materials in microelectronics was first demonstrated in the mid-1970s. The discovery was based on a simple experiment of doping polyacetylene with iodine, which resulted in a tremendous increase in its electrical conductivity, making it close to those of metals. Following these initial experiments, functional organic materials have attracted significant attention over the last three decades as electro-active materials for the development of printable and flexible electronic devices, low-power flexible displays/electronic papers, wearable electronics, printable sensors, and flexible solar panels.

Our research is focused on the theoretical design and synthetic development of new organic molecular, macromolecular, and polymeric π-conjugated materials for new-generation (opto)electronic devices and nanotechnology applications. In particular, we are interested in p-/n-/ambipolar semiconductors, low band gap donor-acceptor polymers, low-LUMO π-systems, hot-exciton fluorescent molecules, green-solvents soluble high-performance semiconductors, semiconductors with scalable synthesis, and thermally responsive molecules. The nano-/micro-structures formed by these organic materials in thin-films lead to organic surface enhanced Raman spectroscopy (o-SERS), thin-film transistors (OTFTs), photovoltaics (OPVs), light-emitting diodes/transistors (OLEDs and OLETs), and multiplex encoded surfaces (physically unclonable functions-PUFs).
