Preferred Definitions:    Ar2=naphthalene ring connected at 2,7-position;    Ar1,Ar3,Ar4=benzene ring connected at 1,3-position;and    Arb=monovalent group consisting of fluoranthene ring, dibenzophenanthrene ring, or benzochrysene ring (all optionally substituted), and having triplet energy of 2.1 eV or more.    EXAMPLE - (In g) 9,9'-dimethyl-2,7-dibromofluorene (4.8), (6-(fluoranthen-3-yl)naphthalen-2-yl)boranediol (5.6), tetrakis(triphenylphosphine)palladium (1.2), dimethoxyethane (50 ml), and sodium carbonate aqueous solution (25 ml) were heat-refluxed under stirring for 8 hours. The solid obtained by filtration of deposited crystal after reaction completion was washed with water, methanol and hexane, and dried under reduced pressure to obtain 3-(6-(7-bromo-9,9-dimethyl-9H-fluoren-2-yl)-naphthalen-2-yl)-fluoranthene (6.1) with a yield of 68%. The obtained compound (6), 4-vinylphenylboronic acid (1.5), tetrakis(triphenylphosphine)palladium (1.2), dimethoxyethane (50 ml), and sodium carbonate aqueous solution (25 ml) were heat-refluxed for 10 hours under stirring. The solid obtained by filtering the deposited crystal after reaction completion was washed with water, toluene and acetone, and dried under reduced pressure to obtain 3-(6-(9,9-dimethyl-7-(4-vinyl-phenyl)-9H-fluoren-2-yl)-naphthalen-2-yl)-fluoranthene as pale yellow solid (4.7) with a yield of 75%. The obtained compound (2) and benzoyl peroxide (20 mg) were dissolved in tetrahydrofuran (15 ml), and polymerized at 70 degrees C for 48 hours. The reaction mixture was reprecipitated thrice using tetrahydrofuran and methanol, and then ethanol. A high-molecular compound (1.08) was obtained with a weight average molecular weight of 20000. An organic electroluminescent element obtained using the high-molecular compound had an initial luminance of 5000 cd/m2 and a brightness half life of 640 hours.
