| This course gives an overview of the fieldof functional soft materials based on organic
building blocks. 1. Self-assembly in the design of soft materials: Introduction to soft materials; an overview of the non-covalent forces in the context of the structural and thermodynamic origin of molecular recognition processes leading to self-assembly. (3L) 2. Molecular switches and stimuli-responsive materials: Azobenzene, dithienylethene, spiropyran and hydrazone based switches and their exploitation in the design of functional materials which respond to external stimuli (pH, light, etc). (3L) 3. Liquid crystals: Definition and historical perspective of liquid crystals; mesogens and mesophases; thermotropic and lyotropic liquid crystals; applications in liquid crystal displays, photonic crystals and sensing. (3L) 4. Supramolecular catalysis: Macrocyclic cavitand molecules and self-assembled metallocages as confined reaction vessels; catalysis on micellar and vesicular surfaces. (3L) 5. Supramolecular polymers and gels: Examples of supramolecular polymers in organic and aqueous media using H-bonding, metal coordination, host-guest complexation, pi-pi stacking interactions, etc; molecular gels from small organic and amphiphilic molecules. (4L) 6. Multicomponent self-assembled systems: The principle of size control and compartmentalization in supramolecular assemblies; self-sorting. (2L) 7. Photochemistry of the self assembled systems and chromophores: Exciton coupling theory, Photochemistry of Vision (4L) 8. Energy and electron transfer processes in supramolecular systems. Photochemistry of natural photosynthesis. (4L) 9. Chiral assemblies and their optical probing. Introduction of Circular Dichroism spectroscopy. (4L) 10. Assembly of organic semiconductors. Inference of self assembly on the optical and electronic properties of semiconductors (4L) |
