    1,7-diazaperylene in Organic Field Effect Transistors
    (Wiley-V C H Verlag Gmbh, 2022) Yumusak, Cigdem; Mayr, Felix; Wielend, Dominik; Kahraman, Bilge; Kanbur, Yasin; Langhals, Heinz; Irimia-Vladu, Mihai
    A thorough material characterization of 1,7-diazaperylene via multiple investigation techniques (cyclic voltammetry, photoluminescence, photoluminescence excitation, impedance spectroscopy) was performed to understand its applicability in organic electronic devices. The recorded data of this perylene derivative was placed in conjunction with the respective data of the parent perylene molecule, and the behavior of this novel compound in organic electronic devices (planar diodes and field effect transistors explained). Although no photovoltaic effect behavior was recorded in planar diodes where 1,7-diazaperylene was employed both as a donor as well as an acceptor, the perylene derivatives proves functional as dielectric layer in organic field effect transistors.

    N,N?-Substituted quinacridones for organic electronic device applications
    (Royal Soc Chemistry, 2023) Saadi, Donia; Mayr, Felix; Yumusak, Cigdem; Wielend, Dominik; Cobet, Munise; Kahraman, Bilge; Irimia, Cristian Vlad
    N,N '-Substituted quinacridones are a novel class of commercially available quinacridones for organic electronics which are reported here. In this study, we performed in-depth investigations of the material properties of these molecules i.e. their optical and charge transport properties, infrared-active vibrations (FTIR), electrochemical reduction and oxidation properties, thin film forming and processability, and finally performance in organic field effect transistor devices. We show that substitution plays a critical role in the charge transport properties, with methyl substituted amine being the most favorable, followed by di-phenyl and finally di-butyl.
