Fluorophore compounds and methods for their use are disclosed. The fluorophores contain a 2-dicyanomethylen-3-cyano-2,5-dihydrofuran (DCDHF) moiety and one or more donor groups conjugated to the 2-dicyanomethylen-3-cyano-2,5-dihydrofuran group. The donor groups can contain atoms with free electron pairs such as oxygen, sulfur, nitrogen, or phosphorous. The fluorophore compounds can be used to label and detect biological molecules and biological structures either in vivo or in vitro.
Halogen-bonded iodonium ion catalysis: a route to α-hydroxy ketones via domino oxidations of secondary alcohols and aliphatic C–H bonds with high selectivity and control
been developed from benzylic secondary alcohols employing catalytic iodonium ions stabilized by DMSO. The reaction proceeds through an unprecedented sequential oxidation of alcohols to ketone and its α-hydroxylation in a controlled manner. The spectroscopic evidences establish the possibility of formation of a stable halogen–bonded adduct between DMSO and iodonium ions.

The area of contactbetween two objects was detected by using the strong enhancement of the fluorescence of rigidochromic probe molecules attached to one of the surfaces. Confinement of the molecules suppresses nonradiative decay and turns on the fluorescence. The approach is demonstrated by imaging of the contact area of a plastic sphere in contact with a flat glass surface. Our results agree excellently
