Fluorination Enhances NIR-II Fluorescence of Polymer Dots for Quantitative Brain Tumor Imaging

Here, we describe a fluorination strategy for semiconducting polymers for the development of highly bright second near-infrared region (NIR-II) probes. Tetrafluorination yielded a fluorescence QY of 3.2 % for the polymer dots (Pdots), over a 3-fold enhanc

A NOVEL QUINOXALINE COMPOUND FOR ULTRAVIOLET ABSORBERS

PURPOSE: A novel quinoxaline compound, isomer thereof, precursor drug thereof, or pharmaceutically acceptable salt thereof is provided to absorb UVA and UVB. CONSTITUTION: A quinoxaline compound is denoted by chemical formula 1. An UV absorber or pharmaceutical or cosmetic composition for antiaging contains the quinoxaline compound, isomer thereof, precursor drug thereof, or pharmaceutically acceptable salt, hydrate, or solvate thereof as an active ingredient.

Synthesis and preliminary physical properties of new neutral tetraalkoxy-substituted nickel bis(1,2-dithiolene) complexes

Nineteen neutral nickel bisdiphenylethenedithiolene complexes [Ni(dpedt)2], including seventeen new compounds, were synthesized and characterized by a new short, efficient and multigram-scale synthetic method. Preliminary physical investigations show that these complexes are electron-withdrawing materials exhibiting good thermal stability and high molecular absorption coefficient in the near-infrared spectral region. Electrochemical and optical properties of [Ni(dpedt)2] depend strongly on the nickel bis(1,2-dithiolene) core and very slightly on the alkyl chain lengths or configurations. These highly soluble coordination compounds are potential candidates as acceptor solution-processable materials for active layers in organic electronic devices, such as field effect transistors or photovoltaic devices.
