The achievement of high ionic conductivity in single-ion conducting polymer electrolytes is one of the important aims for various electrochemical devices including modern lithium batteries. One way to enhance the ionic conductivity in polyelectrolyte syste ...
The lower critical solution temperature (LCST) behavior of novel poly(ethylene glycol) (PEG)-based copolymers bearing multiple functional groups, obtained by anionic ring-opening (co)polymerization (AROP), has been investigated. Variable comonomer ratios o ...
The combination of ring closure and spatial constraints has a fundamental effect on the statistics of semiflexible polymers such as DNA. However, studies of the interplay between circularity and constraints are scarce and single-molecule experimental data ...
Fluorescent sensors are valuable tools for investigating the biochem. of metal cations, notably calcium and zinc. Most probes rely on quenching of photoinduced electron transfer as a fluorescence turn-on mechanism. The information that can be obtained from ...
A reversible, reaction-based sensor for biol. mobile zinc was designed, prepd., and characterized. The sensing mechanism of this probe is based on the zinc-induced, ring-opening reaction of spirobenzopyran to give a cyanine fluorophore that emits in the de ...
Polyelectrolytes (PEL) and PEL complexes formed by electrostatic interaction are recognized as compounds with a remarkable potential for a wide field of applications. However, comprehensive knowledge about electrostatic and structural influences on the pol ...
In this paper, we describe a novel methodology for fabricating conductive epoxy-polythiophene network films by simultaneous photoinduced step-growth and cationic ring opening polymerization processes. For this purpose, formulations containing a bifunctiona ...
Colloidal drug and prodrug conjugates have unique targeting characteristics for tumor vasculature from the blood and for the lymphatics draining a tissue injection site. Tioguanine and tioguanine-generating prodrugs have been investigated as anticancer and ...
Gold and rhodium nanoparticles stabilized by a cationic polymer can be readily modified by anion exchange to afford nanoparticles that may be dispersed in a wide range of organic solvents and ionic liquids. The catalytic activity of the Rh nanoparticle dis ...
The substrate scope of the [2+2] cycloaddn.-cycloreversion (CA-CR) reaction between electron-deficient (2,2-dicyanovinyl)benzene (DCVB) or (1,2,2-tricyanovinyl)benzene (TCVB) derivs. and N,N-dimethylanilino (DMA)-substituted acetylenes was studied. The str ...
