Reversible, zinc-selective chemical reactions that enable imaging biological Zn2+ at long wavelengths

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 ...

SpiroZin1: A Reversible and pH-Insensitive, Reaction-Based, Red-Fluorescent Probe for Imaging Biological Mobile Zinc

Pablo Rivera Fuentes

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 ...

One-pot photoinduced synthesis of conductive polythiophene-epoxy network films

Federica Sordo, Marco Sangermano

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 ...

Reduction-Sensitive Tioguanine Prodrug Micelles

Jeffrey Alan Hubbell, Urara Hasegawa

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 ...

Application of a Versatile Nanoparticle Stabilizer in Phase Transfer and Catalysis

Paul Joseph Dyson, Vincent Laporte, Ilaria Biondi

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 ...

Conformation of Ring Polymers in 2D Constrained Environments

Giovanni Dietler, Guillaume Witz, Kristian Rechendorff

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 ...

Regular Acyclic and Macrocyclic [AB] Oligomers by Formation of Push-Pull Chromophores in the Chain-Growth Step

Pablo Rivera Fuentes

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 ...

From an Epoxide Monomer Toolkit to Functional PEG Copolymers With Adjustable LCST Behavior

Frederik Roman Wurm

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 ...
