Abstract:
PURPOSE: A fullerene-based polymer and an electroluminescent device using the polymer are provided, wherein the polymer is prepared by simple method, is soluble in an organic solvent and can be mixed with other polymers easily. CONSTITUTION: The fullerene-based polymer is represented by the formula 1, wherein R1, R2 and R3 are independent each another and are H, an aromatic or aliphatic alkyl or alkoxy group of C1-C22, an aryl or aryloxy group of C6-C18, cyano group, cyanoethyl group, an alkyl or aryl derivative of silicon, tin and germanium; X is diacetylene, diethynyl aryl or divinyl aryl group, or a single bond; and n is an integer equal to or greater than 1. Preferably n is an integer of 1-1,000. The electroluminescent device contains a luminescent layer comprising the fullerene-based polymer and other polymers.
Abstract:
PURPOSE: Fluorene-like compounds having polyphenylene, polymers thereof and an EL element containing the same are provided. The fluorene-like compounds are used as a principal ingredient of organic and polymeric electroluminescence elements and/or other optical elements. CONSTITUTION: Fluorene-like compounds having polyphenylene are prepared by Diels-Alder reaction of a compound having one or more of cyclopentadienones and a compound having one or more of acetylenes. The fluorene-like compounds are represented by the formula(1), wherein R1, R2, R1' and R2' are the same or different, and are independently a substituent selected from the group consisting of hydrogen, C1 to C22 aliphatic or alicyclic alkyl and alkoxy, C6 to C18 aryl or aryloxy, silicone, alkyl and aryl derivatives of tin or germanium, and halogen atom; Ar and Ar2 are the same or different, and are independently hydrogen, trimethylsillyl, bromine, alkyl, or C6 to C18 aromatics such as phenyl, naphthyl and derivatives thereof; Ar' is a substituent selected from the group consisting of aromatics and hetero compounds such as phenylene, naphthalene, anthracene, fluorene, thiophene, pyrrole, pyridine, aryloxadiazol, triazole, carbazole, arylamine, arylsilane and derivatives thereof; m is 0 or 1; and n is 1.
Abstract:
A fluorene compound and polymers thereof having a polyphenylene group, and EL element comprising the same, which can be prepared through a Diels-Alder reaction of a compound having one or more cyclopentadienone group and a compound having one or more acetylene group and can be used as a core material for organic and polymeric EL element and/or other optical devices.
