Photovoltaic Cells Based on Conducting Polymers and Perylene Diimides: Preprint
NREL has recently begun investing polymer-based photovoltaic cells. We present initial results on a novel energy conversion device that uses both semiconducting polymers and organic small molecules as photoactive layers, using the advantageous properties of both classes of materials. By incorporating polymers into the device, we see results that are surprisingly good for a planar organic device...
متن کاملMultiple-electron transfer in a single step. Design and synthesis of highly charged cation-radical salts.
[structure: see text]. Macromolecules 1c and 2c bearing multiple redox-active sites are synthesized by an efficient palladium-catalyzed coupling of 2,5-dimethoxytolylmagnesium bromide with readily available hexakis(4-bromophenyl)benzene and tetrakis(4-bromophenyl)methane. These macromolecular electron donors undergo reversible oxidation at a constant potential of 1.15 V vs SCE to yield robust, ...
متن کاملTwisted perylene dyes enable highly fluorescent and photostable nanoparticles.
Polymeric fluorescent nanoparticles with covalently embedded perylene fluorophores were developed by facile synthesis strategy and their advanced features of extremely high fluorescence intensity, non-photoblinking and excellent photostability were experimentally confirmed at the single nanoparticle level.
متن کاملHighly conducting lyotropic liquid crystalline mesophases of pluronics (P65, P85, P103, and P123) and hydrated lithium salts (LiCl and LiNO₃).
Demand for ionically conducting materials, as membranes and electrodes, is one of the driving forces of current research in chemistry, physics, and engineering. The lithium ion is a key element of these materials, and its assembly into nanostructures and mesophases is important for the membrane and electrode technologies. In this investigation, we show that hydrated lithium salts (such as LiCl·...
متن کاملHighly fluorescent water-soluble polyglycerol-dendronized perylene bisimide dyes.
Water-soluble perylene tetracarboxylic acid bisimides (PBIs) with terminally linked polyglycerol dendrons of four different generations have been synthesized. These PBI dyes reveal a strong dendritic effect, enabling outstanding fluorescence quantum yields in water up to almost 100% for the highest dendron generation.
