Fluorinated Polymer, Method of Making, and Use in Electrochemical Cell

Low specific capacity and low charge/discharge rate of current cathodic materials are the bottle-neck for the next generation electrochemical energy storage devices, particularly for “on-demand applications.” Current batteries rely on transition metal salts (e.g. LiMO2, LiMPO4) and mixed metal oxide lithium salts as cathodic materials. The...

Metal-Organic Super-Containers

Container structures are ubiquitous in nature, with examples including viruses and various protein assemblies. Researchers at the University of South Dakota have designed and synthesized a series of synthetic container molecules termed metal-organic super-containers (MOSCs) because they are assembled from container precursors, metal ions, and organic...

Electron-Deficient Fluorous Porphyrins and Their Use in Organic Solar Cells

Fluorinated aromatics and related materials offer many advantages over non-fluorinated materials in a variety of different optoelectronic devices such as, but not limited to, organic light emitting diodes (OLEDs), organic field-effect transistors (OFETs), organic solar cells (OSCs), and dye-sensitized solar cells (DSSCs). These fluorinated materials...

Electrical Ion Sensors Based on MOSCs

Although metal organic frameworks (MOFs) have proven to be effective for electronic ion sensing, they lack key desirable characteristics such as solution processability due to their insolubility in most common solvents. Metal-organic supercontainers (MOSCs) have a significant advantage over MOFs, as they can be readily dispersed in solution while retaining...

Fluorinated ultra-thin film

Fluoropolymers have experienced widespread use as functional materials in applications ranging from water purification to energy storage. Production of large area, two-dimensional (2D), ultra-thin, semifluorinated polymer films is expected to have significant impacts on multiple fields. Some of these fields are organic electronics and optoelectronics...
