New optical chemosensors were developed for determination of molecular oxygen, pH, carbon dioxide as well as several ionic species. They are based on phosphorescence metal ligand charge transfer complexes. Signals were measured with frequency domain luminescence techniques.
Besides the development of new sensors this project includes the synthesis of new indicator dyes and polymer materials and also the development of new spectroscopic techniques. Beside sensor development, the adaptation of optical sensors for numerous applications is the major part of this research topic.
