Design, and ease of operation. The advancement of this technology hinges on the development of innovative membrane materials. While polymer-based membranes have been used for a long time, their efficiency is limited by the trade-off between permeability and selectivity. Thus, the quest for novel membrane materials is a primary focus for academia and industry. Nanoporous materials, such as zeolites, metal-organic frameworks (MOFs), and covalent organic frameworks (COFs), based membranes provide better separation performance due to their ordered porous structures. COFs, in particular, are promising for advanced gas and liquid-phase separation processes because of their crystalline nature, well-defined porosity, tunable functionalities, and versatile architectures.1 Since their introduction, covalent organic framework membranes (COFMs) have witnessed rapid advancements, highlighting their significant potential in membrane-based separation technologies.2 Not limited to molecular separation, recently, COFMs have also emerged as potential semiconducting materials for photonics and optoelectronic device applications.3 In my talk, I will discuss our recent works on optical conductivity of free-standing 3D COFMs using terahertz (THz) spectroscopy, nonlinear optical (NLO) response and catalytic properties of free-standing COFMs, along with molecular separation potentials.
