Abstract: An organic light-emitting material contains a 6-silyl-substituted isoquinoline ligand. The organic light-emitting material is a metal complex containing a 6-silyl-substituted isoquinoline ligand and may be used as a light-emitting material in a light-emitting layer of an organic electroluminescent device. These new complexes can provide redder and saturated emission and meanwhile demonstrate a significantly improved lifetime and efficient and excellent device performance. Further disclosed are an electroluminescent device and a compound formulation including the metal complex.

Abstract: A metal complex containing three different ligands which may be used as a light-emitting material in a light-emitting layer of an organic electroluminescent device. These new complexes can not only achieve device performed desired to be adjusted or improved by adjusting substituents but also have the effect of effectively controlling increase of the evaporation temperature. Further disclosed are an electroluminescent device and a compound formulation including the metal complex.

Abstract: Disclosed are an intermediate drug having synergistic anticancer activity and a polyethylene glycol-coupled synergistic anticancer drug, and a method preparing therefor and use thereof. The intermediate drug has the general structural formula of (I), and the polyethylene glycol-coupled synergistic anticancer drug has the general structural formula of (II). The drugs achieve the combined medication of various anticancer drugs and avoid the toxic reaction caused by the interaction among the drugs or by the pharmacokinetics of the drugs when taking various anticancer drugs, facilitate overcoming the multidrug resistance of cancers, have a synergistic effect, and can be used for preparing anticancer medicaments and for treating cancers.
