چکیده
COVER PICTURE Mandy Hecht, Tobias Fischer, Paul Dietrich, Werner Kraus, Ana B. Descalzo, Wolfgang E. S. Unger, and Knut Rurack* Retrieving quantitative molecular information from macroscopic areas in a reliable manner at micrometric resolution is a challenging task, yet essential for a better understanding and control of the assembly of (bio)chemical entities on a functional surface. In their Full Paper, Knut Rurack and co-workers introduce fluorine-containing moieties to boron-dipyrromethene (BODIPY) dyes, thus making them versatile probes for dual-method surface analysis (p. 25 ff.). The cover picture shows a bright fluorescent dye (green halo) containing a high number of fluorine atoms (blue) for the assessment of reactive amino groups on a glass surface by two complementary surface analytical techniques, non-destructive fluorescence scanning and quantitatively traceable X-ray photoelectron spectroscopy (XPS), both applied to the same individual samples.

Fluorinated Boron-Dipyrromethene (BODIPY) Dyes: Bright and Versatile Probes for Surface Analysis
A family of bright boron-dipyrromethene-type fluorophores with a high number of fluorine atoms (F-BODIPYs) has been developed and characterized by X-ray crystallography and optical spectroscopy. The introduction of 3,5-bis(trifluoromethyl)phenyl and pentafluorophenyl moieties significantly enhances the photostability of such dyes, yielding for instance photostable near-infrared (NIR) fluorophor...
متن کاملBoron dipyrromethene (BODIPY) functionalized carbon nano-onions for high resolution cellular imaging.
Carbon nano-onions (CNOs) are an exciting class of carbon nanomaterials, which have recently demonstrated a facile cell-penetration capability. In the present work, highly fluorescent boron dipyrromethene (BODIPY) dyes were covalently attached to the surface of CNOs. The introduction of this new carbon nanomaterial-based imaging platform, made of CNOs and BODIPY fluorophores, allows for the exp...
متن کاملYellow Fluorescent Semiconducting Polymer Dots with High Brightness, Small Size, and Narrow Emission for Biological Applications
Cross-linked polymer dots with intense and narrow yellow emission were designed using boron-dipyrromethene (BODIPY) polymer as the acceptor and poly[9,9-dioctylfluorenyl-2,7-diyl-co-1,4-benzo-{2,1'-3}-thiadiazole] (PFBT) polymer as the donor. The emission fwhm's of the polymer dots (Pdots) were 37 nm. CL-BODIPY 565 Pdots were about 5 times brighter than commercial quantum dots (Qdots) 565 under...
متن کاملA Review of the Synthetic Strategies for the Development of BODIPY Dyes for Conjugation with Proteins
Conjugation of fluorophores to proteins is fundamental to several biotechnological applications and in the last decades boron-dipyrromethene (BODIPY) dyes started to be used in this field. BODIPYs are dipyrrin derivatives complexed to difluoroboryl that possesses several attractive photophysical properties. Herein we reviewed the synthetic methodologies published by academic and non-academic re...
متن کاملDevelopment of 2,6-carboxy-substituted boron dipyrromethene (BODIPY) as a novel scaffold of ratiometric fluorescent probes for live cell imaging.
Ratiometric fluorescent probes based on boron dipyrromethene (BODIPY) were developed based on a novel design strategy, in which a change of the electron-withdrawing character of the 2,6-substituents resulting from reaction with a target molecule generates a fluorescence wavelength change.
