Nanoscale domains of donor and acceptor materials are crucial for charge generation in organic photovoltaic devices. These domains are difficult to achieve reproducibly in blended materials, but could be engineered into single-material active layers composed of donor–acceptor block copolymers (BCPs). In this work, we report the synthesis and purification of two novel fully conjugated BCPs, P3HT...

The ring closing metathesis within an ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF(6)]), a 'green' solvent tetraethylene glycol (TEG), and their equimolar mixture is investigated through the intramolecular excimer formation of 6-(1-pyrenyl)hexyl-11-(1-pyrenyl)undecanoate [1]. The excimer formation efficiency correlates directly with the inverse of the bulk viscosity o...

An orthogonal self-assembled system consists of different structures which coexist independently. Furthermore, the characteristic properties of the respective "base systems", i.e. of the systems which contain only one of the structures, are retained in the orthogonal self-assembled system. We have identified gelled bicontinuous microemulsions as orthogonal self-assembled systems and reported in...

Artificial ion transporters are synthetic molecules mimicking at a functional level the activity of naturally occurring ion channels or carriers. In the frame of cyclodextrin mimicry, we recently described the synthesis and conformational properties of new carbohydratebased macrocycles having the glucoside units connected through 4,6-linked phosphodiester linkages, named CyPLOS (cyclic phosphat...

Non-aqueous carbonate solvents have been the main choice for development of lithium-ion batteries, and similarly most research on sodium-ion batteries performed using carbonate-based solvents. However, differences between sodium lithium – in term chemistry/electrochemistry properties as well electrode materials used open up opportunities to a new look at that attracted little attention electrol...

Because of the high affinity of the thiol groups to a metal such as gold and zinc, we can conjugate metal nanocrystals with chemical compounds which contain thiol such as cysteine, cyctein contained peptide, and thiol-modified nucleic acids including DNA. Among them, T. Pellegrino et al. investigated Gold-DNA conjugates in detail by a comprehensive gel-electrophoresis study based on 1200 gels. ...

in this paper, the measurement of the viscosity of zno in ethylene glycol, propylene glycol, mixture of ethylene glycol and water (60:40 by weight), and a mixture of propylene glycol and water (60:40 by weight) and the thermal conductivity in ethylene glycol and propylene glycol as base fluids in the range of temperature from 25 ºc to 60 ºc are investigated. the results indicate that as the tem...

For a monolayer of 2,3-di-phytanyl-sn-glycerol-1-tetraethylene glycol-D,L-a-lipoic acid ester lipid (DPTL) self-assembled (SAM) at a gold electrode surface we propose a new method to determine the charge number per adsorbed molecule and the packing density (area per molecule) in the monolayer. The method relies on chronocoulometry to measure the charge density at the SAM covered gold electrode ...

Kathryn Rosica of the Chemical Manufacturers Association raised an interesting point in her letter (EHP vol. 102, p. 1006). Neither the term "glycol ethers" nor the term "ethylene glycol ethers" strictly identifies a class of chemicals whose members all share a common distinctive toxicological profile. As Rosica correctly noted, "Higher molecular weight ethylene glycol monoethers that have been...
