Study of organic molecular compound by x-ray radiation
Stejkora, Jakub ; Richtera, Lukáš (referee) ; Salyk, Ota (advisor)
Derivates of diketopyrrolopyrrole are coloured pigments with potential use in field of organic semiconductor structures. Their electrical attributes such as conductivity, photocon- ductivity and electroluminescence relate to their crystal structures, that determine charge transport path through the compound. The work deals with determination of these structures by using x-ray diffractometry. The diffractogram based on known crystalografic structure of diketo-dipyridyl-pyrrolo-pyrrole is modeled by available software and measured diffractogram is used for structure re-modeling. This method is used for other related derivates with unknown crystal structure.
