FRET function of polymeric ionic liquid film containing rhodamine moieties for exhibiting emissions by excitation at wide wavelength areas

This paper reports synthesis of an imidazolium-type fluorescent polymeric ionic liquid film containing rhodamine moieties, which shows fluorescence resonance-energy-transfer (FRET) property, resulting in emissions by excitation at wide wavelength areas. First, radical copolymerization of two polymerizable ionic liquid, which had one and two polymerizable groups, respectively, was carried out with AIBN as an initiator to confirm whether a transparent polymeric ionic liquid film could be produced. Then, radical terpolymerization of the two ionic liquids with a rhodamine derivative having a polymerizable group was performed under the similar conditions as that for the above copolymerization to give the fluorescent polymeric ionic liquid film containing rhodamine moieties. The fluorescence spectra of the resulting film exhibited emissions due to the rhodamine group by excitation at wide wavelength areas. This result indicated occurrence of FRET from the polymeric ionic liquid units to the rhodamine moieties in the film because the excitation-wavelength-dependent emissions due to the polymeric ionic liquid were partially overlapped with an absorption peak due to the rhodamine group.

XANTHENE-BASED PURPLE DYE COMPOUND, COLORING RESIN COMPOSITION FOR COLOR FILTER CONTAINING SAME AND COLOR FILTER USING SAME

The present disclosure relates to a purple dye compound for a color filter and a coloring resin composition for a color filter containing the same. The novel xanthene-based purple dye compound or the polymer dye compound obtained using the same as a monomer has superior solvent resistance and superior miscibility with a pigment in an organic solvent. Further, it exhibits superior heat resistance, chemical resistance, light resistance and brightness due to the homopolymer structure. Accordingly, a coloring resin composition containing the same can be used widely as a dye for synthetic resins and synthetic fibers, as a coloring agent for polymer materials, for a color filter used in LCDs, PDPs, etc., and so forth.
