  • Bromination Improves the Electron Mobility of Tetraazapentacene
    作者:Hilmar Reiss、Lei Ji、Jie Han、Silke Koser、Olena Tverskoy、Jan Freudenberg、Felix Hinkel、Michael Moos、Alexandra Friedrich、Ivo Krummenacher、Christoph Lambert、Holger Braunschweig、Andreas Dreuw、Todd B. Marder、Uwe H. F. Bunz

    A cyclocondensation of TIPS‐ethynyl‐substituted diaminoarenes with in situ obtained 4,5‐dibromocyclohexa‐3,5‐diene‐1,2‐dione has led to the synthesis of tetrabromotetraazapentacene (BrTAP). BrTAP is easily reduced to its air‐stable radical anion and electron mobilities >0.56 cm2 V−1 s−1 can be achieved in thin‐film transistors.
    TIPS-乙炔基取代的二氨基芳烃与原位获得的4,5-二溴环六-3,5-二烯-1,2-二酮的环缩合反应导致合成了四溴四氮杂并五苯(BrTAP)。BrTAP容易还原为其空气稳定的自由基阴离子,并且在薄膜晶体管中可实现> 0.56 cm 2  V -1  s -1的电子迁移率。

    The introduction of bromine substituents into cyclopentannulated tetraazapentacenes allows post-functionalization, for example through Sonogashira coupling and Rosenmund-von Braun reaction. The altered properties of the resulting new compounds were examined by experimental and computational methods, and the potential use as organic field-effect transistors was demonstrated.

  • Halogen Bonding in Diaza-Triisopropylsilyl-Tetracene Crystals?
    作者:Michael Porz、Frank Rominger、Uwe H. F. Bunz
    DOI:10.1021/cg5011538
    日期:2014.11.5
    Four halogenated triisopropylsilylethynyl (TIPS)-tetracene derivatives were synthesized, their single crystal structures and optical and electronic properties were examined. Both, diiodo-TIPS-diazatetracene and dibromo-TIPS-diazatetracene showed herringbone arrangements, in which the halogen atoms are directed toward the nitrogen atoms of a neighboring molecule with slightly lower distances than the van der Waals radii between halogen and nitrogen atoms. Computations of the electrostatic potentials showed the availability and the strength of s holes, so that we assume a weak halogennitrogen bonding. Tribromo-TIPS-diazatetracene delivered a 2D-brick wall structure with no sign of a halogen bonding. Dibromo-TIPS-tetracene crystallized neither in a herringbone nor in a brick wall motif. These results show that for halogenated azaacenes at least weak halogennitrogen interactions exist.
