DOE BES: Directed Assembly of Bio-inspired Supramolecular Materials for Energy Transport and Capture: Mesoscale Construction of Functional Materials in Hydrodynamic Flows. Final Project Report
- Univ. of Illinois, Urbana-Champaign, IL (United States)
The precise engineering of mesoscale structures based on molecular building blocks holds enormous promise to catalyze the development of new functional materials for advanced energy technologies. Bio-inspired and synthetic/bio-hybrid systems can play a key role in this effort due to their inherent programmable function and high degrees of sequence control. Despite recent progress, the ability to precisely control the supramolecular assembly of bio-hybrid molecules remains a central problem in the field. Our research aims to fundamentally understand the assembly mechanism of bio-hybrid materials, specifically focusing on sequence-controlled synthetic pi-conjugated oligopeptides. Moreover, we aim to develop new methods for the directed assembly of materials based on tailored fluid flows to guide the emergent structural, optical, and electronic properties of synthetic pi-conjugated peptides. Overall, our team has made substantial progress on this project through four major Thrusts: (1) Understanding the role of kinetics on the assembly process of synthetic π-conjugated peptides. (2) Probing the role of chemistry on the structural properties of these materials. (3) Real-time in situ investigation of the sol-gel transition and assembly of π-conjugated peptides. (4) Achieving large-area macroscopic alignment and assembly of these materials. In the following report, we explain major research progress in each of these research Thrusts.
