TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The charge transportable monomer and charge transportable oligomer have 2 or more types conjugation units in arbitrary combination. The conjugation unit is optionally substituted aniline having valency of 2-4, thiophene, furan, pyrrole, ethynylene, vinylene, phenylene, naphthalene, anthracene, imidazole, oxazole, oxadiazole, quinoline, phosphorus, silole, silicon, pyridine, pyrimidine, pyrazine, phenylene vinylene, fluorene, carbazole, triarylamine, metal or metal-less phthalocyanine and/or metal or metal-less porphyrin. The charge transporting substance is a quinone diimine derivative, which is an oligo aniline derivative of formula (1 or 4) or its antioxidant. The electron accepting dopant substance is a sulfonic acid derivative of formulae (5,6).R1-R11=H, hydroxyl, halogen base, amino, silanol, thiol, carboxyl, sulfonic acid, phosphoric acid, phosphoric acid ester, ester, thioester, amide, nitro, monovalent hydrocarbon, organo oxy, organo amino, organo silyl, organo thio base, acryl group or sulfone base;A,B=divalent base of formulae (2,3);m,n=integer greater than 0;m+n=less than or equal to20;D=benzene, naphthalene, anthracene, phenanthrene or heterocyclic ring;R12,R13=carboxyl or hydroxyl group;R14-R18=H, (un)substituted monovalent hydrocarbon group or halogen atom;X=O,S, NH or single bond;A in formula (6)=H, halogen atom, O, S, S(O), S(O2), (un)substituted monovalent hydrocarbon, N, Si, P or P(O) group;y=valency of A, which is greater than or equal to1;andx=number of sulfonic acid group bonded to benzene ring portion in 1,4-benzodioxane structure, which is 1-4.    TECHNOLOGY FOCUS - POLYMERS - Preferred Property: The charge transportable varnish has solid content of 1 %. The number of defects in charge transportable film having film thickness of 30 nm is 100 or less, when detecting the foreign material in 0.5 microns at a capture rate of 80 %, measuring using Surfscan 6220 (KLA-Tencor tabular surface foreign-material test apparatus). EXAMPLE - Phenyl tetraaniline (in g) (0.05) and 5-sulfo salicylic acid (0.0986) were dissolved in 1,3-dimethyl-2-imidazolidinone (5.8846), in nitrogen atmosphere. Cyclohexanol (8.8268) was added to the resulting solution, and stirred to obtain a charge transportable varnish having solid content of 1%. An uniform charge transportable thin film was formed using the varnish, and had favorable planarization property and luminous efficiency. Number of defects on the film surface was 59.
