The development of catalytic reactions has revolutionised the synthesis of organic molecules and polymers. In contrast, catalysis is virtually unexplored as a route to molecular and macromolecular inorganic materials. Over the past decade our group has been at the forefront of the development of catalytic reactions with main group substrates. In particular, we have been involved in a broad expansion of this field in the area of dehydrogenation and dehydrocoupling processes that allow access to a wide range of catenated structures based on elements across the p-block. Such catalytic pathways using main group substrates represent an increasingly attractive and convenient alternative to traditional routes such as salt metathesis and reductive coupling reactions. Applications of this work involve the fields of hydrogen storage and transfer, functional inorganic polymers, and ceramic thin films.

Our research group has been at the forefront of the development of "Living" Crystallization-Driven Self-Assembly (CDSA) of Block Copolymers and other building blocks such as planar π-stacking organic molecules and metallocycles to form well-defined colloidally-stable 1D and 2D materials with tunable dimensions, spatially controlled surface and core chemistries, and potential applications from information storage and nanoelectronics to biomedicine. A focus has been on polyferrocenylsilane block copolymers, which were developed in our group, but our more recent work has also involved block copolymers with crystallizable π-conjugated or biodegradable segments. Together with our collaborators, we are currently investigating the fundamentals of the fascinating living CDSA process and also a range of potential applications of the resulting phase-separated thin films and core-shell nanostructures (micelles) as nanowires, nanoscopic barcodes, self-assembled heterojunctions, catalysts, and as magnetic dot precursors and in drug/gene delivery.
