Our team is interested in problems related with mechanical to chemical energy conversions, simply called as mechanochemistry. We are also active in synthesizing materials and producing new material systems,which respond to external stimulus. Our favorite stimulus is mechanical input, but we also mix-and-match other stimuli for building up complex systems. Understanding the molecular mechanism of electrostatics is a 2000-year-old problem. We are pursuing an organic chemist’s approach, which recently led to a paradigm shift in electrostatics research.
We are a research team at Bilkent University, Department of Chemistry working on the synthesis, characterization, and application of lyotropic liquid crystals and nanostructured/mesostructured materials.
Global energy consumption is expected to increase exponentially by 2050 mainly due to the increase in population and energy consumption per person. The overall energy demand could only be met by discovering alternative methods for energy production. Hydrogen economy is one of the promising candidates of the clean alternative energy sources. It has high energy content per mass and produces water as a product.Our main objective is to introduce and develop novel electrocatalysts and photocatalysts that target the half reactions of water splitting; water oxidation and hydrogen evolution.

Conducting organic polymers (COP)s are pi-conjugated systems (see below) which combine the properties of plastics which those of metals or semi-conductors. After their discovery, the focus was on their electrical properties and applications as molecular wires and as materials for batteries were investigated. It turned out that optical properties, like electrochromism and light absorption are more useful and currently extensive research is carried out on light harvesting systems, light emmitting diodes, and organic fiels effect transistors. My interests focus currently on theoretical investigation of absorption and photoelectron spectra and on the nature of the charge carriers in COPs.
In Suzer Research Group, we focus our research into; Layer-by-layer deposition and their antibacterial applications, electrical investigation on nano-scale structures with dynamic XPS, tribochemistry investigation of various materials, wettability of surfaces.
The research in our group combines synthetic organic, supramolecular and polymer chemistry to prepare functionalm aterials such as supramolecular polymers, cucurbituril containing rotaxanes and polyrotaxanes, water soluble conjugated polymers, carbon nanotubes-conjugated polymer nanocomposites, functional and mechanically-stable conjugated polymer nanoparticles which have potential applications in the use of polymeric opto-electronic devices (LEDs, solid state lighting and photovoltaic devices), chemo- and bio-sensors, molecular switches. We are also interested in the design and synthesis of nanoparticles and nanocapsules based on light-emitting polymers for biomedical applications such as live cell imaging and theranostic nanomedicine.

Our research will focus on the development of new environmentally benign and cost-effective catalytic transformations using inexpensive, non-toxic and earth-abundant transition metals. We will also seek to discover and/or use biorenewable, green solvents for a broad range of synthetic transformations.In our group, we will utilize various types of non-covalent interactions to tackle certain challenging problems of synthetic organic chemistry. Also, these interactions will be used in crystal engineering for the design and discovery of new two- and three-dimensional frameworks with targeted functions.
Our research is centered on developing new measurement tools/methods around the ideas of electrochemistry. The measurements we are trying to develop all answer needs that are currently unmet.We are working on developing measurement tools that are mostly inspired by problems of energy storage and conversion systems. As humanity is trying to meet the ever increasing energy demand, new energy storage and conversion technologies are being developed that need to be understood, investigated and compared properly. We are developing the toolbox for proper measurement and investigation of these systems.
