Selective detection of Al3+ and citric acid with a fluorescent amphiphile

Kay Severin, Ziya Köstereli

An amphiphilic fluorescent dye with a disulfonated BODIPY head group and a heptadecyl side chain is described. In buffered aqueous solution, the amphiphile can form aggregates with a critical micelle concentration of similar to 20 mu M. The aggregation of ...

Laser desorption/ionization mass spectrometry of dye-sensitized solar cells: identification of the dye-electrolyte interaction

Ulf Anders Hagfeldt

Dye-sensitized solar cells (DSCs) have great potential to provide sustainable electricity from sunlight. The photoanode in DSCs consists of a dye-sensitized metal oxide film deposited on a conductive substrate. This configuration makes the photoanode a per ...

Design of Ru(II) sensitizers endowed by three anchoring units for adsorption mode and light harvesting optimization

Mohammad Khaja Nazeeruddin, Filippo de Angelis

We report the design, synthesis and computational investigation of a class of Ru(II)-dyes based on mixed bipyridine ligands for use in dye-sensitized solar cells. These dyes are designed to preserve the optimal anchoring mode of the prototypical N719 sensi ...

Engineering of Ru(II) dyes for interfacial and light-harvesting optimization

Michael Graetzel, Mohammad Khaja Nazeeruddin, Filippo de Angelis, Kuan-Lin Wu, Gabriele Marotta

A new Ru(II) dye, Ru(L1)(L2) (NCS)(2), L1 = (4-(5-hexylthiophen-2-yl)-4'(4-carboxyl-phenyl 2,2'-bipyridine) and L2 = (4-4'-dicarboxy-2,2'- bipyridine), labelled MC112, based on a dissymmetric bipyridine ligand for improved interfacial and optical propertie ...

Thermal stability of the DSC ruthenium dye C106 in robust electrolytes

Michael Graetzel, Shaik Mohammed Zakeeruddin, Péter Kalman Péchy

We have investigated the thermal stability of the heteroleptic ruthenium complex C106 employed as a sensitizer in dye-sensitized solar cells. The C106 was adsorbed on TiO2 particles and exposed to 2 different iodide/triidode based redox electrolytes A and ...

Acetylene-bridged dyes with high open circuit potential for dye-sensitized solar cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Pascal Comte, Thomas Moehl, Fabrizio Giordano, Aswani Yella, Yongjoo Kim, Chi-Lun Mai

A series of simple metal-free organic dyes MS1-MS3 have been designed and synthesized, and their optical, electrochemical, and photovoltaic properties were investigated. The molecular structures are based on a push-pull framework with a triphenylamine, nap ...

Photocatalytic degradation of Remazol Brilliant Blue (R) by sol-gel derived carbon-doped TiO2

Ravindranathan Thampi, Michael Jon Mattle

A simple, cheap and reproducible method to produce a C-doped TiO2 photocatalyst is presented, which can harvest visible light. This doped catalyst is able to degrade a stable organic dye molecule, Remazol Brilliant Blue (R) (RBB), under sunlight and visibl ...

Live Intracellular Super-Resolution Imaging Using Site-Specific Stains

Suliana Manley, Lina Carlini

Point localization super-resolution imaging (SR) requires dyes that can cycle between fluorescent and dark states, in order for their molecular positions to be localized and create a reconstructed image. Dyes should also densely decorate biological feature ...
