Quinoline derivatives represented by formula (1) wherein two or more of substituents R to R are each a group of formula (2). In general formula (2), Q is a carbo- or hetero-aryl group; and the number (n) of double bonds is preferably 1 to 3. Use of such derivatives in an organic EL device provided with a layer of an organic compound and two electrodes sandwiching the layer as the organic compound gives devices emitting yellow to red light with high brightness and high efficiency. Further, doping a hole transport layer with such derivatives realizes organic EL devices capable of emitting lights of resultant colors (e.g., white) composed of lights from light-emitting and hole transport layers.

A metal ion coordinated complex crystal is composed of cation of a nitrogen-containing heterocyclic aromatic compound, anion of triiodine and metal ion. The complex crystal can be used as light-polarizing particles having a stable and strong polarizability which is resistant to ultra violet, an excellent heat resistance, excellent moisture resistance and excellent insolubility.

A resin-molded product includes a phenol-based oxidation inhibitor, and a thiol-based compound. The thiol-based compound reacts chemically with a coloring substance (or a compound having a quinone-type structure) resulting from the phenol-based oxidation inhibitor to interrupt a long conjugated system arising in the coloring substance. As a result, the absorption due to the coloring substance is canceled in the visible light region. Thus, the resin-molded product is inhibited from yellowing.

A complex crystal is composed of anion of triiodine and cation of a fused compound consisting essentially of at least one nitrogen atom and at least 3 aromatic fused rings. Since the complex crystal has such a stable structure, it shows excellent heat resistance and excellent moisture resisting property. Furthermore, the complex crystal has light-polarizing performance because of an arrangement of the molecular chain of iodine. Moreover, the complex crystal exhibits excellent polarization because of an interaction between the fused compound and iodine. Therefore, the complex crystal is suitable for use as light-adjusting particles of a light valve or a light-adjusting glass.
