Koch F, Berkefeld A, Speiser B, Schubert H.
PMID: 28976037
Chemistry. 2017 Nov 21;23(65):16681-16690. doi: 10.1002/chem.201704599. Epub 2017 Nov 09.

Sulfur-bridged binuclear structures [2M-2S] play a pivotal role in a variety of chemical processes such as bond breaking and formation and electron transfer. In general, structural persistence is deemed essential to the respective function but owing to the lack...

Chemistry. 2015 Mar 16;21(12):4628-38. doi: 10.1002/chem.201406486. Epub 2015 Feb 11.

The coordination chemistry of cyclic stannylene-based intramolecular Lewis pairs is presented. The P→Sn adducts were treated with [Ni(COD)2] and [Pd(PCy3)2] (COD = 1,5-cyclooctadiene, PCy3 = tricyclohexylphosphine). In the isolated coordination compounds the stannylene moiety acts either as an acceptor...

Hydrodabcyl: A Superior Hydrophilic Alternative to the Dark Fluorescence Quencher Dabcyl.

Anal Chem. 2017 Nov 21;89(22):11893-11897. doi: 10.1021/acs.analchem.7b03488. Epub 2017 Nov 07.

Dark fluorescence quenchers are nonfluorescent dyes that can modulate the fluorescence signal of an appropriate fluorophore donor in a distance-dependent manner. Dark quenchers are extensively used in many biomolecular analytical applications, such as studies with fluorogenic protease substrates or...
