Our Research Expertise

Establishing the correlation between varied excited states of dimeric structures with their unusual optoelectronic behavior comprised the central goal of our Research Centre. This, in turn, may open up the possibility to design improved compounds in terms of excited state behavior tunability through substitutions. In view of the above, tailor-making the advantageous stacking arrangements via chemical substitution is proposed for various congeners of acenes, perylene bisimides, and donor-pi-acceptor-based molecular systems. Properties Investigated:

  1. Ground State Properties: Geometry Optimizations to obtain stabilized structures, Predict stability, Dipole moment, Solubility, Frequency (IR Spectrum), Vibrational frequencies, Visualization of Vibrational Modes: Stretching vs. Bending

  2. Thermochemical Calculation: Internal Energy, Enthalpy, Entropy, Gibb’s Free Energy, Chemical Potential, Hardness

  3. Excited states Phenomenon: UV spectra, allowed vs forbidden transitions, Molecular orbital analysis HOMO vs. LUMO. Fluorescence and Phosphorescence property Simulation, Excited States (Singlet and Triplet) Calculation: Jablonski Diagram, Orbital Contribution and Transition Dipole Moment. Electron and Hole Density Distribution Maps: Charge Transfer: LMCT or MLCT

  4. Solvent effect: Implicit model vs. explicit mode

  5. Reaction Mechanisms: Single-Point Energy, Potential Energy Diagrams, Interaction Energies, Transition state structures, Activation Energy

  6. Computer Aided Drug Design: Structure-based Drug Design (target-ligand docking): Comparative modeling of protein (Homology modeling), Thermodynamical criteria assessment, Molecular Docking using Autodock vina (For docking of multiple ligands), Protein file, ligand file, and grid setting for Docking parameters: Blind docking vs. site-specific docking, Docking analysis: Understanding how drugs function at the molecular level.

Carbon Nanosheets by Morphology-Retained Carbonization of Two-Dimensional Assembled Anisotropic Carbon Nanorings

Angew Chem. Int. Ed. 2018, 57, 9679-9683, Wiley-VCH, German Chemical Society

Two-dimensional (2D) carbon nanomaterials possessing promising physical and chemical properties find applications in high-performance energy storage devices and catalysts. However, large-scale fabrication of 2D carbon nanostructures is based on a few specific carbon templates or precursors and poses a formidable challenge. Now a new bottom-up method for carbon nanosheet fabrication using a newly designed anisotropic carbon nanoring molecule, CPPhen, is presented. CPPhen was self-assembled at a dynamic air–water interface with a vortex motion to afford molecular nanosheets, which were then carbonized under inert gas flow. Their nanosheet morphologies were retained after carbonization, which has never been seen for low-molecular weight compounds. Furthermore, adding pyridine as a nitrogen dopant in the self-assembly step successfully afforded nitrogen-doped carbon nanosheets containing mainly pyridinic nitrogen species.
