<p>Poly (4,5,9,10-tetrahydropyrene-2,7-diyl) derivs. of formula (I) are new (where, R1-R4 = H, 1-22C alkyl (opt. contg. one or more non-adjacent CH2 gps. substd. by O, -COO-, -OOC- and/or phenylene), aryl(oxy) (opt. a substd on the aryl ring with one or more of 1-22C alkyl, 1-22C alkoxy Br, Cl, F, CN and/or NO2)., Br, Cl, F, CN, NO2 or 2-23C carboalkoxy; and n = 10-150). Also claimed are: (i) prepn. of (I) by reacting one or more cpds. of formula (II) with bis(1,5-cyclooctadiene) nickel (O) and a 2,2'-bipyridine in an inert organic solvent (mixt); (ii) electroluminescent materials contg. (I); (iii) electroluminescent devices contg. at least one layer of the material; and (iv) prepn. of (II) by reacting a 4,5,9,10-tetrahydropyrene deriv. with bromine in an inert organic solvent in the presence of a gp. VIII transition metal on an active carbon carrier.</p> |
