Fragmentation behavior of poly(methyl methacrylate) during matrix-assisted laser desorption/ionization.

Tomomi Iura et al.

Rapid communications in mass spectrometry : RCM, 29(2), 155-162 (2015-02-03)

Matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) has been widely utilized for the structural characterization of various synthetic polymers. However, polymer sample molecules can occasionally decompose even in the MALDI process depending on the measurement conditions. In this work, the fragmentation

Consequences of chirality on the dynamics of a water-soluble supramolecular polymer.

Matthew B Baker et al.

Nature communications, 6, 6234-6234 (2015-02-24)

The rational design of supramolecular polymers in water is imperative for their widespread use, but the design principles for these systems are not well understood. Herein, we employ a multi-scale (spatial and temporal) approach to differentiate two analogous water-soluble supramolecular

Organic-inorganic azafullerene-gold C(59)N-Au nanohybrid: synthesis, characterization, and properties.

Georgios Rotas et al.

Chemistry (Weinheim an der Bergstrasse, Germany), 20(45), 14729-14735 (2014-09-17)

Azafullerene (C59 N) was functionalized using a Mannich-type reaction and then subsequently condensed with lipoic acid to yield dithiolane-modified C59 N. In the following step, the extended dithiolane moiety from the C59 N core was utilized to decorate the azafullerene

Breaking aggregation in a tetrathiafulvalene-fused zinc porphyrin by metal-ligand coordination to form a donor-acceptor hybrid for ultrafast charge separation and charge stabilization.

Atanu Jana et al.

Dalton transactions (Cambridge, England : 2003), 44(1), 359-367 (2014-11-11)

A novel electron rich, tetrathiafulvalene fused zinc porphyrin, (TTF)4PZn, has been newly synthesized and characterized using spectral and electrochemical methods. In spite of the presence of eight t-butyl groups, (TTF)4PZn exhibited appreciable aggregation in solution. Scanning electron microscopic (SEM) imaging
