Porous two-dimensional (2D) and three-dimensional (3D) organic frameworks have garnered great interests for their potential as a new catalog of multifunctional materials, on account of well-defined structural precision, high periodicity and long-range ordering. The unlimited choice of electroactive building blocks enables rational design and synthesis of functional frameworks as promising candidates for applications in optoelectronics, solar fuel and energy storage, though there are practical issues that limit the materials performance. In this talk, I will outline several of such roadblocks and our approaches in addressing these challenges. A few case studies include soluble supramolecular frameworks, porous graphitic frameworks and thin film covalent organic frameworks. Through the control of bonding, framework structure and form factor, we demonstrate the development of framework materials with enhanced properties, including efficient photocatalysts, high performance cathodes for lithium ion batteries and responsive organic semiconductors.

The seminar can also be followed either from an equipped room with visio-connection in EPFL Lausanne or with a computer with Jabberguest but you are kindly requested to contact our IT support 1 day before (37679 - [email protected]).
