Our research primarily targets the development and physical properties of the transition metal based inorganic molecular materials with switchable electronic structures that give rise to suitable photophysical, photochemical, chemical, electronic, magnetic and magneto-optical properties and their structure-property correlation.
Incorporating functionality in inorganic molecular materials is an important focus of research and is capable of exhibiting diverse physical responses when subjected to various external conditions and has become very topical with regard to technological applications, for instance, in displays, memories, switches, spintronics, magneto-optics, thermometry, storage and sensors (e.g. photonic sensors).
Our research aim to develop and exploit this exciting frontier of functional molecular materials in different forms of structure and dimensions.
The following research directions would be undertaken in our group:
1. Probing the molecular and nanoscale spin state switching
2. Switchable functional networks
3. Hybrid switchable materials involving magnetic, conducting and/or luminescent functionalities
Our research will heavily involve synthesis, design and physical characterizations of inorganic molecular materials. We are particularly focused on synthesizing new molecule-based switchable inorganic compounds in combination with structural and spectroscopic measurements to investigate the physical property/functionality of particular interest. The synthesis requires novelty and essentially leads to new insights of fundamentally interesting and technologically useful properties.
We use wide variety of techniques to explore the physical properties of the switchable molecular materials. Techniques include temperature dependent static and time-resolved optical absorption and luminescence, temperature dependent magnetic response and photo-magnetism, X-ray diffraction and photo-crystallography, TEM in combination with EDX, STM, Spin-coating, drop-casting and dip-coating (or constructive lithography) and photoconductivity. These studies are further integrated with theoretical modeling to understand the mechanistic insights of the switching phenomenon. In addition, EPR, Mössbauer spectroscopy and temperature dependent Raman Spectroscopy are also used. The combination of novel synthesis and state-of-the-art spectroscopies offers the powerful opportunity to discover, develop, and ultimately harness the physical properties of functional molecular materials
