Yuan Fang’s innovative research lays at the interface of organic and materials chemistry. Her doctoral studies at KU Leuven focused on unravelling the structural-function relationship and fundamental science of molecular assemblies on surfaces using scanning probe microscopy (SPM) techniques. As a NSERC postdoctoral fellow at McGill University, Fang is interested in developing novel π-conjugated Covalent Organic Frameworks (COFs) and their implementation in optoelectronic devices (thin film field-effect transistors, photovoltaics, etc).

Rapid and facile solvent-free mechanosynthesis in a cell lysis mill: preparation and mechanochemical complexation of aminobenzoquinones

Rapid agitation and self-heating in the lysis mill enabled thermally-demanding reactions without external solvent, providing yields comparable to those obtained by conventional solution chemistry, ball milling and melt chemistry. The lysis mill is also suitable for coordination-based reactions, demonstrated by the mechanosynthesis of a mononuclear Ni(II) meta-benzoquinonemonoimine complex.

Dynamic control over supramolecular handedness by selecting chiral induction pathways at the solution–solid interface

Here, we have combined the sergeant–soldiers principle with temperature-dependent molecular selfassembly to unravel a peculiar chiral amplification mechanism at the solution–solid interface in which, depending on the concentration of a sergeant–soldiers solution, the majority handedness of the system can either be amplified or entirely reversed after an annealing step, furnishing a homochiral surface. Two discrete pathways that affect different stages of
two-dimensional crystal growth are invoked for rationalizing this phenomenon and we present a set of experiments where the access to each pathway can be precisely controlled. These results demonstrate that a detailed understanding of subtle intermolecular and interfacial interactions can be used to induce drastic changes in the handedness of a supramolecular network.
