Here, we introduce a general strategy to synthesize near-infrared luminescent probes by conjugating a Yb(3+) chelate to established fluorescein-based probes. As the first demonstration, we present a complex, based on the green-emitting probe DAF-4, that responds to nitric oxide (NO) in aqueous solution with a significant increase in luminescence intensity at 980 nm.

Here we report a new class of potent CA inhibitors which bind the zinc ion: the dithiocarbamates (DTCs). They coordinate to the zinc ion from the enzyme active site in monodentate manner and establish many favorable interactions with amino acid residues nearby. Several low nanomolar CA I, II and IX inhibitors were detected.

Upon reduction of 1 with Na/Hg under dinitrogen molecular nitrogen is cleaved to form [(t-BuPOCOP)Mo(i)(N)](-). The origin of the N atom was confirmed using (15)N(2). Protonation of [(t-BuPOCOP)Mo(i)(N)](-) results in the formation of a neutral species in which it is proposed that the proton has added across the Mo-P bond.

Optomechanical properties originate from the collection and amplification of many local deformation events in individual photoswitching entities due to their 3D organization. The basic concept of optomechanics is introduced, related recent achievements in the photoactuation of soft materials are highlighted, and a new approach, based on the optimization of the individual photoresponse at the single-molecule level, is outlined. Optomechanical systems constitute a fundamental approach to alternative utilization of solar energy and a platform for the development of future responsive soft materials...

Our key finding is the decomposition of the compound on the surface, leaving only sulfur behind. This was supported by X-ray photoelectron spectroscopy (XPS), cyclic voltammetry (CV) and scanning tunneling microscopy (STM). The modification leads to observation by STM of well-known as well as new phases for the S modified Au(111) surface.
