Charge-modulated self-assembly and growth of conjugated polyelectrolyte-polyoxometalate hybrid networks.
SCHMITT, WOLFGANG; EVANS, RACHEL (2014)Self-assembly of an anionic polyoxometalate with cationic conjugated polyelectrolytes leads to hybrid supramolecular networks whose dimensionality is controlled by the chain length and steric charge distribution. -
Detection of explosive vapors with a charge transfer molecule: self-assembly assisted morphology tuning and enhancement in sensing efficiency.
SCHMITT, WOLFGANG (2010)Use of a fluorescent organic molecule consisting of binaphthyl functionalized with donor?acceptor substituted stilbenes for the detection of dinitrotoluene (DNT) and trinitrotoluene (TNT) vapors and enhancement in its ... -
A facile "bottom-up" approach to prepare free-standing nano-films based on manganese coordination clusters.
SCHMITT, WOLFGANG (2013)We present herein a novel method to prepare free-standing Dried Foam Films (DFFs) whereby individual polynuclear manganese complexes cover quantitatively the holes of micro-grids; the fabricated, homogeneous films have a ... -

Formal encapsulation of [Fe(H2O)6]3+ by dinuclear {Fe2(hpdta)} units leads to a nonanuclear S = 13/2 Fe(III) oxo-cluster showing magnetic hysteresis
SCHMITT, WOLFGANG (2005)Under solvothermal conditions the unprecedented nonanuclear Fe(III) aggregate [Fe9(mu3-O)4(mu-OH)4(hpdta)4]5- is formed through the formal encapsulation of [Fe(H2O)6]3+ by four [Fe2(hpdta)(H2O)2]+ units: the aggregates ... -
Hierarchical supramolecular fullerene architectures with controlled dimensionality
SCHMITT, WOLFGANG (2005)Self-assembly of a fullerene derivative with long alkyl chains in different solvents results in the formation of hierarchically- ordered supramolecular assemblies with well-defined 1, 2 and 3Darchitecturessuchasvesicle s, ... -
Ligand displacement for fixing manganese: relevance to cellular metal ion transport and synthesis of polymeric coordination complexes.
