Near-infrared reflective properties of perylene derivatives

Dyes and pigments with high reflectance in the near-infrared (NIR) region can extensively control the heat buildup. Perylene-based pigments exhibit considerable reflectance in the NIR region. The reflectance of a material depends upon a number of factors,

A New π-conjugated 1,7-diphenoxy-perylene bisimide: Synthesis, characterization, photophysical and electrochemical properties

A novel π-conjugated 1,7-diphenoxy-perylene bisimide (perylene diimides, PDIs) (4) was synthesized starting from 1,7(6)-diphenoxyperylene-3,4,9,10-tetracarboxylic bisanhydride (3). N,N’-bis(4-hydroxyphenyl)-perylene-3,4,9,10-tetracarboxy bisimide (1) was synthesized and characterized also for the comparison between a non-bay substituted symmetrical perylene diimide and the bay substituted symmetrical perylene diimide with the same substituents at the PDI imide positions. Positive and weak solvatochromic effect for the compounds 3 and 4 was apparently observed in polar media. The absolute positions of LUMO and HOMO values of 1 and 3 in solution were ?3.775 eV/?6.035 eV and ?3.971 eV/?6.041, respectively. The HOMO, LUMO and Eg values for the compound 4 were not calculated due to the non-resolved reduction peaks most probably due to aggregation.

METHOD FOR PRODUCING DYE POLYMER, DYE POLYMER AND USE OF THE SAME

Disclosed are a production process of a dye polymer having a dye content of from 1 to 50 wt%, and the dye polymer and its use. The production process includes subjecting an addition-polymerizable monomer to living radical polymerization by using, as a polymerization initiator, a dye having a polymerization initiating group enabling the living radical polymerization. The dye polymer and a composition of the dye polymer and a pigment are useful as good coloring agents for various products or articles. The colored products or articles are high in transparency, and are provided with high added value. The dye polymer can also be used as a dispersant for pigments, thereby making it possible to afford pigment dispersions excellent in dispersion properties and dispersion stability.
