Abstract: Sensing elements, sensor systems and methods for determining the concentration of oxygen and oxygen-related analytes in a medium are provided. The sensing element comprises a solid polymeric matrix material that is permeable to oxygen or an oxygen related analyte and an indicator that is covalently bonded to the solid polymeric matrix material. The indicator is a luminescent platinum group metal polyaromatic chelate complex capable of having its luminescence quenched by the presence of oxygen.

Abstract: In a method of making an organic electroluminescent device, a transfer layer is solution coated on a donor substrate. The transfer layer includes a polymerizable, amorphous matrix with a light emitting material disposed in the matrix. The transfer layer is then selectively patterned on a receptor. The polymerizable, amorphous matrix is then polymerized. Examples of patterning methods include laser thermal transfer or thermal head transfer. The method and associated materials can be used to form, for example, organic electroluminescent devices.
