発明の名称 (英語) PHOSPHOR AND USE OF SAME NEW
発明の概要(英語) A phosphor which is composed of a maleimide compound represented by general formula (1). (In the formula, R1 represents a hydrogen atom, an alkyl group having 1-6 carbon atoms or a halogen atom; A represents a substituted or unsubstituted phenyl group, or a substituted or unsubstituted alkyl group; B represents a functional group which is bonded, via a nitrogen atom, to the 4-position of the five-membered ring of maleimide, and which is a substituted or unsubstituted morpholino group, a substituted or unsubstituted piperidyl group, or a substituted or unsubstituted dialkylamino group; and C represents a functional group which is bonded, via a nitrogen atom, to the carbon atom in the 3-position of the five-membered ring of maleimide, and which is a substituted or unsubstituted phenylamino group represented by Ph-NH- (wherein Ph is a phenyl group), a substituted or unsubstituted morpholino group, a substituted or unsubstituted piperidyl group, or a substituted or unsubstituted dialkylamino group.)
従来技術、競合技術の概要(英語) BACKGROUND ART
And the organic fluorescent substance, the light wavelength conversion material for a solar cell, an organic EL light-emitting dye, dye laser, being utilized in a wide range of fields such as bio-imaging is, as a characteristic of the organic fluorescent material, a high concentration under a significant decrease in luminance due to concentration quenching is known to cause. In order to avoid these problems, a low molecular or polymer organic phosphor host material and a solvent are dispersed uniformly at the molecular level to lean the use of the conventional organic fluorescent material in the utilization of the means.
On the other hand, the conventional organic fluorescent material on the other hand, a significant increase in aggregate emission, it has been found that a so-called aggregation induced light-emitting molecule, it is assumed that the organic fluorescent material and overcome the problem of, such as medical and industrial fields of a new application of the organic fluorescent substance is expected to be implemented (Patent Document 1, 2, Non-Patent Document 1, reference 2).
However, the aggregation of the conventional light-emitting molecule is induced, non-patent document 1, 2 described in many of the light-emitting molecules induced aggregation of the aromatic rings and the backbone and the complexity, the synthesis requires a multistep synthesis.
Therefore, the present inventors previously disclosed in Patent Document 1, as shown in 2, carbon, nitrogen, and hydrogen with a relatively simple structure, light emission color can be controlled and in the visible region, and light emission induced aggregation amino maleimide derivative in the organic light-emitting body was developed. These amino maleimide derivative, an amine group substituted on the imide substituents on the side of the N- changing the electronic state of the emission wavelength by a three-dimensional effect can be changed. Thus, light emission color in the visible region in the vicinity of 500nm can be controlled precisely.
In addition, non-patent document 3 3 2 at the position of the maleimide and introduced into the aromatic ring via a sulfur dithio maleimide derivative 2,3-, converted into red light material is obtained.
