  abstract  = {In this work, two new quadrupolar A-π-D-π-A chromophores have been prepared featuring a strongly electron- donating diborene core and strongly electron-accepting dimesitylboryl F(BMes2) and bis(2,4,6-tris(trifluoromethyl)phenyl)boryl (BMes2) end groups. Analysis of the compounds by NMR spectroscopy, X-ray crystallography, cyclic voltammetry and UV-vis-NIR absorption and emission spectroscopy indicated that the compounds possess extended conjugated π-systems spanning their B4C8 cores. The combination of exceptionally potent π-donor (diborene) and π- acceptor (diarylboryl) groups, both based on trigonal boron, leads to very small HOMO-LUMO gaps, resulting in strong absorption in the near-IR region with maxima in THF at 840 and 1092 nm, respectively, and very high extinction coefficients of ca. 120,000 M-1cm-1. Both molecules also display weak near-IR fluorescence with small Stokes shifts.},

  abstract  = {A series of NHC-supported 1,2-dithienyldiborenes was synthesized from the corresponding (dihalo)thienylborane NHC precursors. NMR and UV-vis spectroscopic data, as well as X-ray crystallographic analyses, were used to assess the electronic and steric influences on the B=B double bond of various NHCs and electron-donating substituents on the thienyl ligands. Crystallographic data showed that the degree of coplanarity of the diborene core and thienyl groups is highly dependent on the sterics of the substituents. Furthermore, any increase in the electron- donating ability of the substituents resulted in the destabilization of the HOMO and greater instability of the resulting diborenes.},

Carbene eignen sich die erhaltenen Addukte als Ausgangsverbindungen zur Realisierung verschiedener Strukturmotive. Mit geeigneten {\"U}bergangsmetallfragmenten gelingt die Darstellung von sigma-Boran-Komplexen bzw. Basen-stabilisierter Boryl-Komplexe, welche mittels spektroskopischer Methoden sowohl im Festk{\"o}rper, als auch in L{\"o}sung untersucht wurden. Ebenfalls gelingt die Synthese Basen-stabilisierter Borirane und einer tetraedrischen Borid-Spezies. Zudem wird ein selektiver Zugang zu Basen-stabilisierten Diborenen entwickelt, wobei deren Bindungssituation und Reaktivit{\"a}t im Detail diskutiert wird. So kann das B=B-Fragment in polymere Spezies eingebunden werden oder als Ligand an {\"U}bergangsmetalle koordinieren.},
