Organic Synthesis and Application

The Feng Group will focus on the research on the design and synthesis of dynamic functional molecules and materials that mimic molecular behavior in organisms. We start with small molecules, demonstrate their properties and then use them as tools for the exploration of materials and biomimicry in collaboration with physicists, biologists and chemical engineers. The scientific questions that our group is interested in answering are how we can learn from biomolecules to achieve those fantastic life-like functions in the nano-world in addition to discovering the origin of homochirality, self-replication, autonomous motion, structural transformation and ultimately — life.

Dynamic Materials with Nanoscopic Transformations

Dynamic Materials with Nanoscopic Transformations

Mechanically interlocked architectures- which contain topologically complex building blocks (monomers)- will exhibit extraordinary properties on account of new degrees of freedom. While maintaining the same topology changing the relative relationship between monomers will transform the material significantly. To make dynamic materials at the macroscale switchable monomers at the nanoscale are required since a small change will make a big difference. Our current project applies topologically complex and controllable structures to construct materials in order to fulfill dynamic functions.

Template-Directed Stereoselective Autocatalysis

Template-Directed Stereoselective Autocatalysis

Classic stereoselective reactions require chiral ligands or the introduction of a chiral center. Autocatalytic reactions, however, produce stereoisomerically enriched products from achiral precursors. Exploring the origin of chiral amplification can be used for asymmetric synthesis. Introducing recognition sites to reactants can bring templation to asymmetric bond formation which will boost the stereoselectivity of desired products. Our project also discovers the origin of homochirality in biomolecules and the chiral amplification in the prebiotic synthesis.

Biomolecular-Driven Molecular Motors in Water

Biomolecular-Driven Molecular Machines in Water

To apply artificial moleclar machines for medical applications, they need to be capable of operating sustainably in water. Our project explores chemical fuels and their waste products that are biocompatible and environmentally friendly and integrate molecular machines with biomolecules to operate in a biomimicking environment. The biological fuels that drive the motor could be chosen from coenzymes that also involved in cellular respiration. The molecular machines apply presumably for drug delivery for cancer diagnosis and therapy. 

Functional Molecular Fluorescent Dyes

Functional Molecular Fluorescent Dyes

Push–pull fluorescent dyes- which feature electron donating (D) substituents connected to electron accepting (A) substituents- have been investigated as environmentally sensitive fluorophores. The design and synthesis of fluorescent organic compounds containing push–pull chromophores have emerged as an active area of research over the past two decades as a result of their potential applications in the fields of photovoltaics, non-linear optics, organic light emitting diodes (OLEDs), fluorescent sensors, and bioimaging. Our project investigates the design and synthesis of new building blocks of fluorescent dyes which leads to dynamic properties based on the supramolecular interactions. The dyes are useful to explore the fundamental principles of intermolecular and intramolecular electron transfer with the collaboration with optical physicists and theoretical chemists.
