Abstract: A condensed-cyclic compound represented by Formula 1 and an organic light emitting diode including the same:

Abstract: Non-peptide GnRH agents capable of inhibiting the effect of gonadotropin-releasing hormone are described. Such compounds and their pharmaceutically acceptable salts, multimers, prodrugs, and active metabolites are suitable for treating mammalian reproductive disorders and steroid hormone-dependent tumors as well as for regulating fertility, where suppression of gonadotropin release is indicated. Methods for synthesizing the compounds and intermediates useful in their preparation are also described.

Abstract: A conductive organopolysiloxane composition is provided which includes (A) 100 parts by weight of an organopolysiloxane; and (B) 0.1 to 800 parts by weight of a conductive material obtained by subjecting a member selected from the group consisting of a conductive metal, a conductive metal compound, a filler surface-treated with a conductive metal and a filler surface-treated with a conductive metal compound, to surface treatment with a compound selected from the group consisting of a compound represented by the formula (1) and a compound represented by the formula (2). ##STR1## wherein R.sup.1 represents --O-- or --NH--, and R.sup.2 represents a hydrogen atom or a phenyl group. This composition is useful for the formation of a silicone rubber having a sufficient electrical conductivity and also stably retainable of electrical conductivity almost without undergoing a change in electrical conductivity even in a high-temperature environment.

Abstract: Active hydrogen-containing fluorochemical is used as a foam stabilizer for polyurethane foams. For example, rigid or flexible polyurethane foams with high or low density and uniform cellular structure are prepared using fluoroaliphatic radical-substituted poly(oxyalkylene) polyols as foam stabilizers.
