TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: The gel component containing conductive polymer is obtained by dissolving the conductive polymer in an organic solvent. The coated gel component on the substrate is heated to form organic thin film, and the organic solvent remained in the thin film is removed.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Solvent: The organic solvent contains 30 vol.% or more of dichlorobenzene or trichlorobenzene. The organic solvent is 1,2,4-trichlorobenzene. Preferred Method: The thin film is obtained by coating gel component by inkjet printing method, dispenser printing method, bar-coat printing method, screen-printing method or flexographic-printing method. Preferred Property: The organic thin film has film thickness of 1 nm-100 mu m.    TECHNOLOGY FOCUS - POLYMERS - Preferred Unit: The conductive polymer contains cyclopentane-containing repeating unit of formula (1, 2, 3 or 12) consisting of 9,9-dialkyl fluorene diyl group or 9,9-dialkyl fluorene-4-bithiophene group.ring A ring B=aromatic ring optionally substituted by alkyl, alkoxy, alkylthio, aryl, aryloxy, arylthio, arylalkyl, arylalkoxy, aryl alkoxythio, arylalkenyl, arylalkynyl, amino, silyl, substituted silyl halogen atom, acyl, acyloxy, imino, amide, imide, monovalent heterocyclic group, carboxyl, substituted carboxyl or cyano;R1-R4=H, 1-20C linear, branched or cyclic alkyl, 6-60C aryl, 4-60C heterocyclic compound, cyano containing 1-20C linear, branched or cyclic alkyl, H or F;X=O, S or selenium;andAr1=bivalent aromatic hydrocarbon group or bivalent hetercyclic group.Preferred Compound: The conductive polymer is of formula (4, 5 or 6).R1-R4=same as defined above;R=terminal group chosen from H or a substituent;p=10-10000;andm,n=1-10.Preferred Method: The conductive polymer is obtained by ribbing method or shearing stress applying method. Preferred Composition: The conductive polymer contains high order phase. EXAMPLE - Poly(9,9-dioctyl fluorene) having weight average molecular weight of 80000 and glass transition of 80degrees C was dissolved in 1,2,4-trichlorobenzene, and the resultant solution was gelatinizes at room temperature for 12 hours. The resultant solution (1.5 wt.%) was spin-coated on a glass substrate, and dried at 200degrees C for 10 minutes to form an organic thin film. The organic electroluminescent element formed using the organic thin film had excellent electrical property and luminance property.
