Proper Design

Mixed ligand metal–organic frameworks (MOFs) have resolutely established themselves as a class of excellent solid state sorbents for carbon dioxide (CO2) and a proper design of such MOF can potentially improve not only the amount of CO2 adsorption, but also the selectivity of CO2 uptake over other gases and volatiles.

Structural Responses

As the number of framework materials known and characterized in the literature grows, it becomes apparent that they can carry properties rarely encountered in more conventional, dense inorganic materials. Among these materials with unusual physical or chemical properties are the ubiquitous metal–organic frameworks, covalent organic frameworks, dense coordination polymers, and molecular frameworks. Many can respond to stimulation by displaying structural responses and changes in properties that range from counter-intuitive to thermodynamically forbidden. In that, they share large similarities with metamaterials, which are engineered to generate properties not found in “normal” materials. We review here the surprising behavior of these meta-MOFs and other framework materials that display properties “beyond” (μετά) the boundaries of common crystalline materials.<br>

Although metal-organic frameworks (MOFs) or porous coordination polymers have been widely studied, their antimicrobial activities have not yet been fully investigated. In this work, antifungal activity of copper-based benzene-tricarboxylate MOF (Cu-BTC MOF), which is water stable and industrially interesting, is investigated against Candida albicans , Aspergillus niger , Aspergillus oryzae and Fusarium oxysporum . The Cu-BTC MOF can effectively inhibit the growth rate of C. albicans and remarkably inhibit the spore growth of A. niger , A. oryzae and F. oxysporum . This finding shows the potential of using Cu-BTC MOF as a strong biocidal material against representative yeasts and moulds that are commonly found in the food and agricultural industries.

Temperature Conduction

Metal organic frameworks (MOFs) or porous coordination polymers (PCPs) represent a tunable molecular scaffolding that can be adjusted for a breadth of applications. This presentation will concern our efforts towards tailoring MOFs towards making new proton conductors ultimately for fuel cells. A major hurdle in these technologies is an electrolyte capable of conducting protons above 100°C. Higher operating temperatures will enhance electrode kinetics and decrease electrode poisoning among several critical operational benefits. In contrast to the macromolecular approaches typically employed towards these electrolytes, we have used a MOF strategy to generate crystalline networks with acidic pores. These MOFs present options to address higher temperature conduction,1 conduction over 10-2 Scm-1,2 and water stability.3 The emphasis in the talk will concern routes to designing these systems and subsequent challenges in their characterization.
