"The objective of the project is to synthetize and characterize compounds from the group of pyrroles, perylenes and other semiconducting molecular organics with affinity to various gases, namely hydrogen, and to evaluate their ability to serve as a sensing element material in gas sensors. The DPPP will be tested as a reference, than its derivative compounds and other relative compounds with potentially sensing group in molecules will be considered. The molecular and crystallographic conformation inthin films prepared both from solution and vacuum deposition will be focused. Gas absorption influence via electron density state on easily detectable film changes in conductivity and optical properties will be tested. The spatial position of active group in crystal, possibility of gas transport and capture at active position as well as easy gas release will be considered and examined.
