A Facile Route to New and Old Cyclophanes from a Pnictogen-activated Self-Assembly Reaction
The well-defined topology and high strain of cyclophanes has found utility in a number of applications including asymmetric catalysis, insulating plastics, and organic electronics. Unfortunately, the field of cyclophane chemistry has been hindered by a lack of high yielding and functional group tolerant preparative methods for their synthesis. T...

Enhanced Photovoltaic Efficiency by Heterojunction Assisted Impact Ionization
Charge multiplication by impact ionization (II) produces ~1% of the photogenerated charge in silicon photovoltaic (PV) devices under solar illumination and ~30% for photons above the silicon direct band gap. Despite these observations, few efforts have been reported to find materials and structures that optimize the rate of II and thereby conve...

Fractal Interconnects for Neuro-Electronic Interfaces, Including Artificial Retinas
In conditions such as macular degeneration and retinitis pigmentosa, impaired vision is caused by a loss of function in the photoreceptor cells (the rods and cones), which lie within the retina at the back of the eye. However, the rest of the visual system, including the optic nerve and the visual processing centers in the brain, remain intact. If ...

Polymer Light Emitting Devices Based On Interfaces Enabled By Internally Compensated Doped Conjugated Polymers
There is a need for low cost, stable and efficient light-emitting devices for solid-state lighting. Polymer light-emitting electrochemical cells (PLECs) are being actively explored for their potential in this area. The stability and efficiency of current PLECs needs to be improved if they are going to be practical. In order to improve stabi...
