内容介绍：
Porous molecular crystals are an alternative to porous extended frameworks such as zeolites, metal-organic frameworks (MOFs), covalent organic frameworks (COFs), and microporous polymer networks.
Interest in such systems dates back to Barrer’s ‘organic zeolites’, but only recently have these materials started to show properties of potential practical interest.1
One distinguishing property of molecular materials is their solubility: unlike extended frameworks, molecular crystals can be processed in solution into a variety of formats, or even as “porous liquid”.2
They can also show unique physical properties, such as protonic conductivity and perfect shape selectivity for rare gases or organic isomers.3
However, molecular crystals also raise challenges in terms of the purposeful design of solid-state function. This is because the energy landscape for molecular crystals is often not dominated by a single intermolecular interaction, unlike bonded crystalline frameworks such as MOFs and covalent organic frameworks. Hence, molecular crystal engineering has so far failed to become the “new organic synthesis” that has been envisaged.
This talk will discuss strategies for the design and synthesis of new functional organic crystals by using a mixture of intuitive design and computation4, the latter based on tecton assembly rules. We will exemplify this with recent examples of post-synthetic modification of porous organic cages, in which their pore size can be precisely controlled. The tuning of the cage aperture size at atomic level is highly desirable for the separation of guests with close size/shape.5
The second part of the talk will introduce some recent progress in the newly found Materials Innovation Factory. The facility, established in collaboration with Unilever, brings together materials chemistry expertise with the latest computational and robotic equipment to accelerate research and reduce the development time for new products to address societal needs.
