摘要:
An organic light-emitting device includes a first electrode; a second electrode facing the first electrode; and an organic layer between the first electrode and the second electrode, the organic layer including an emission layer. The emission layer includes at least one heterocyclic compound of Formula 1. The heterocyclic compound may be a host or a delayed fluorescent dopant. The organic light-emitting device including the heterocyclic compound may have a low driving voltage, high efficiency, high luminance, and a long lifespan.
摘要:
Mitochondria-targeting potassium sensors and method(s) for making such sensors. The sensor shows a response to potassium and displays a 130-fold dynamic range of fluorescence intensity and high brightness. The sensors response to potassium concentrations was demonstrated to be unaffected by cellular pH value and/or concentrations of other ions. The sensors can be used for monitoring the mitochondrial potassium efflux/influx.
摘要:
The present invention discloses a phosphorus-silicon synergistic flame retardant and the preparation method and use thereof. The phosphorus-silicon synergistic flame retardant provided by the present invention has a structural general formula shown as formula I. A new type of compound containing phosphorus and silicon is prepared by the present invention using the cheap organic boron catalyst, and employing the addition reaction of diphenyl phosphine oxide and derivatives thereof with silicone containing carbon-carbon double bond. Such compounds have the properties of hydrolytic resistance, easy purification, and low synthesis cost, etc. Phosphorus and silicon elements in the molecular structures of such compounds both can act as the flame retardants solely, and meantime can work synergistically, thereby enduing the common polymeric materials with the excellent flame retardant property.
