Original Abstract

Compounds of the group of diketo-pyrrolo-pyrroles, perylenes and other semiconducting molecular organics with affinity to various gases, namely hydrogen, were synthesized and characterized. Their ability to serve as a sensing element material in gas sensors was evaluated. 3,6-di-pyridin-4-yl-2,5-dihydro-pyrrolo[3,4-c]pyrrole-1,4-dione (DPPP) was tested as a reference, than its derivative compounds and other relative compounds with potentially sensing group in molecules were considered. The molecular and crystallographic conformation in thin films prepared both from solution and vacuum deposition was focused. Proton absorption influence on absorption spectra variation and changes in conductivity in gap electrode arrangement were tested. The spatial position of active group in crystal, possibility of gas transport and capture at active position as well as easy gas release was considered and examined. Fabrication of the sensor and electrode material for achieving of high sensitivity and selectivity, rapid response and recovery of such sensing element is also considered.
