Supramolecular Chemistry

Description

Our vision is a supramolecular method that enables the fabrication of functional materials with hierarchical structural features through modular assembly wherein the modular components are encoded with sufficient information for three-dimensional self-assembly into targeted structures. To realize this vision, we need (a) supramolecular tools for molecular assembly at the nanoscale and at the mesoscale and (b) structural characterization of the aggregate structures over multiple length scales. We have been has been using the tools of supramolecular chemistry to assemble organic molecules and polymers into specific structures at multiple length scales.

We demonstrate that MWCNTs can be dispersed in common organic solvents as single tubes using a single hexabenzocoronene (HBC) unit at the end of a poly(methyl methacrylate) (PMMA) chain. The concentration of the HBC-based additive needed to disperse…

We have probed the effect of side chains on the charge transfer dynamics in dyads containing quaterthiophene (QT) donor and naphthalene diimide (NDI) acceptor. The donor and the acceptor are covalently linked using a flexible linker. Four dyads (1-4)…

We report a general strategy for the spontaneous segregation of electron-rich and electron-poor pi-conjugated moieties using mutually phobic aliphatic fluorocarbon-hydrocarbon interactions.
