Abstract

New easily functionalisable and highly fluorescent BOPAHY chromophores are synthesised via a one-pot two-step reaction starting from commercially available pyrrole-2-carbaldehydes and respective acyl hydrazides in the presence of BF3·OEt2. Most importantly, all BOPAHY dyes show excellent photophysical properties with quantum yields up to 0.92. Steady-state spectroscopy and quantum chemical calculations provide a first insight into these promising properties. [ABSTRACT FROM AUTHOR]

8. High-speed electrodeposition of copper–tin–zinc stacks from liquid metal salts for Cu2ZnSnSe4 solar cells.

Author

Steichen, Marc, Malaquias, João C., Arasimowicz, Monika, Djemour, Rabie, Brooks, Neil R., Van Meervelt, Luc, Fransaer, Jan, Binnemans, Koen, and Dale, Phillip J.

Subjects
ELECTROFORMING, LIQUID metals, SOLAR cells
Abstract

Cu2ZnSnSe4-based solar cells with 5.5% power conversion efficiency were fabricated from Cu/Sn/Zn stacks electrodeposited from liquid metal salts. These electrolytes allow metal deposition rates one order of magnitude higher than those of other deposition methods. [ABSTRACT FROM AUTHOR]

13. Electrodeposition of thick palladium coatings from a palladium(II)-containing ionic liquid.

Abstract

The first palladium-containing Liquid Metal Salts (LMS) are presented and shown to be suitable electrolytes for the electrodeposition of palladium. The homoleptic LMS of formula [Pd(MeIm)4][Tf2N]2 or [Pd(EtIm)4][Tf2N]2 (MeIm = N-methylimidazole, EtIm = N-ethylimidazole) have higher melting points than the heteroleptic [Pd(MeIm)2(EtIm)2][Tf2N]2, which is proved to be the most promising electrolyte. The deposition reaction in these LMS was found to be irreversible but smooth and dense palladium layers can be deposited that are crack-free up to a thickness of 10 microns. [ABSTRACT FROM AUTHOR]
