Paper Abstract
Since oxygen concentration is a critical parameter in various applications optical gas sensors are a field of
intensive academic as well as industrial research. Nowadays indicator based optical oxygen sensors comprises in
most cases a light source an immobilized transition metal complex for analyte determination and a detector
system. In view of the fact that miniaturization of sensor elements is a key requirement, a novel electro-optical
sensor device comprising the sensing as well as the light emitting functionality within one layer is demonstrated.
This approach bridges the gap between organic light emitting devices (OLEDs), where transition metal
complexes are used for device efficiency enhancement and classical optical oxygen probes. Based on a OLEDs
comprising platinum-octaethylporphyrin immobilized in a poly(9-vinylcarbazole) we demonstrated the
versatility of this new approach. Furthermore we were able to determine the indicator analyte interaction
principle and showed the reversibility of this process.
