The objectives of this invention are to provide a novel Nile Red luminescent compound capable of emitting a light of which color is nearly crimson, a novel process for producing the same and a luminescent compound capable of emitting at a high luminance a nearly crimson light. This invention relates to a Nile Red luminescent compound emitting red light made by changing C═O in a Nile Red compound to C═CH—Ar, wherein Ar is an aromatic group including fluorine atoms, and by introducing an electron attractive aromatic acetonitrile into the skeleton of the Nile Red compound; a novel process for producing the Nile Red luminescent compound that comprises reacting a Nile Red pigment with an electron attractive aromatic acetonitrile, and a luminescent compound comprising a composition that includes the Nile Red luminescent compound.
本发明的目的是提供一种新型的尼罗红荧光化合物,能够发出接近深红色的光,以及一种能够以高亮度发出接近深红色光的荧光化合物的新型制备方法。本发明涉及一种尼罗红荧光化合物,通过将尼罗红化合物中的C═O改变为C═CH—Ar,其中Ar是包括氟原子的芳香基团,并将电子吸引性芳香基的乙腈引入尼罗红化合物的骨架中,从而发出红色光;一种制备尼罗红荧光化合物的新型方法,包括将尼罗红颜料与电子吸引性芳香基的乙腈反应;以及包括尼罗红荧光化合物的组合物的荧光化合物。
