Abstract: Research in my group is focused on the newest type of fully synthetic nanoporous solid known as metal-organic frameworks (MOFs). The control over porosity and chemical functionality sets these solids above traditional adsorbents yet improving upon current knowledge and understanding is necessary to see MOFs make the transition into practical use.

The ability to functionalise MOFs after their formation is a decided advantage for tuning the properties and thereby enhancing the performance of these materials. This process, known as post-synthetic modification (PSM), has become very important to the field over the past 10 years. Our aim in this area has been to establish thermal methods of PSM and demonstrate the benefits of this approach. In this talk I will present results from my group’s work,1-5 which have centered on the use of porous functionalized IRMOF-9 analogues (see Figure below), and discuss what we see as benefits along with our future direction in this area.
