Switchable Molecular Magnetic Materials Lab
We are working in the interfaces between Inorganic, Physical and Materials Chemistry. Our research focuses mainly on the design and synthesis of new Switchable Molecular Materials (SMMs). These molecular systems exhibit several advantages such as the chemical and structural versatility, low density, solubility towards conventional solvents and also having interesting physical properties such as (Photo)magnetic, Photoluminescence, Electro- and Thermal transport, Magnetocaloric effect and Optical properties. Some of these materials will be anchored with carbon nanotubes or grafted onto silica nanoparticles for the preparation of exciting hybrid materials. Such systems offer appealing future applications for electronic devices, molecular switches and sensors, information storage/processing and high-density recording media. Various physical techniques are used for characterization, such as (variable temperature) FT-IR, UV-Vis (Solid-state and solution), Raman, Differential Scanning Calorimetry, Thermogravimetric Analysis, Cyclic Voltammetry, NMR (Solution and Solid-state), Mass Spectrometry, Single crystal and powder X-Ray Diffraction (under irradiation), EPR, Mössbauer, Electron Microscopy, SQUID Magnetometer (under irradiation) and PPMS Succeptometer.
We are looking for highly motivated students and if you interested about our research work, please email me or visit our department (SSCU, Room no: 003).
