Areas of Interest

Dr. Hogan’s research focuses primarily on supramolecular chemistry, crystal engineering, and hydrogen-bonded metal-organic frameworks (HBMOFs). His group investigates the synthesis and structural characterization of metal-organic and hydrogen-bonded materials, with particular interest in how intermolecular interactions and framework flexibility can be used to achieve molecular recognition, guest inclusion, molecular storage, and separation. Current research includes the development of layered HBMOFs containing transition metals and organic linkers, investigation of small-molecule incorporation, and exploration of the structural and supramolecular properties of these materials. His research utilizes techniques including single-crystal X-ray diffraction, powder X-ray diffraction, and thermogravimetric analysis.

Scholarship & Creative Activity

Dr. Greg A. Hogan’s research on hydrogen-bonded metal-organic frameworks (HBMOFs) represents a distinctive approach to developing flexible, supramolecular materials with potential applications in molecular recognition, separations, storage, and remediation. His work explores how hydrogen bonding, metal–organic connectivity, and layered framework architectures can be deliberately combined to produce materials capable of responding to the size, shape, and chemical nature of guest molecules. A particularly important aspect of his research is the investigation of guest inclusion and coordinative intercalation, demonstrating that HBMOFs can accommodate small molecules within their structures while retaining the overall framework architecture. By combining synthetic chemistry with single-crystal and powder X-ray diffraction and thermogravimetric analysis, Hogan’s research provides insight into the relationship between crystal structure, framework flexibility, and supramolecular function. Collectively, this work advances the understanding of HBMOFs as adaptable materials and establishes a foundation for their future development as “soft” framework systems for selective molecular capture, transport, and remediation.
