Laboratory of Organic materials in Institute of Solid State Physics, University of Latvia in collaboration with the Paris Institute of Nanosciences, Pierre and Marie Curie University is implementing a project „Phthalocyanine architectures for sensor application” within “Osmose” – cooperation programme between France and Latvia for the development of science and technology to investigate new materials for detecting environmental pollution.

The hybrid structure, organic/inorganic semiconductors, based on the organic field-effect transistor and other related devices, are promising candidates for the development of new gas sensors because of their low cost, high sensitivity and especially easy integration in micro-electronic devices.

To make these hybrid devices competitive in term of cost, effectiveness, selectivity and reliability, it is necessary to optimize their properties such as structural, electronic, of reactivity and stability. The objectives of this project is to work jointly on model films such as supramolecular assemblies containing phthalocyanines (Pc) on inorganic surfaces, to understand how their organization modifies their optical and electronic properties and connecting the structure of these assemblies of Pc to the properties of reactivity during exposure to active molecules for potential applications in gas sensors.
