The applicability of inkjet-printed (opto-)electrical devices are hindered by their low lateral resolution, when compared to conventional techniques. The low lateral resolution is mainly caused by the flow and spreading of the functional ink on the s

In the pursuit of novel bishomoconjugated (σ-bishomoaromatic) 4N/7(6)e bonding motifs, (bisseco)pagodane/isopagodane and dodecahedrane-like, caged, proximate-parallel bishydrazines have been designed as suitable host skeletons. The derived radical c

Na4N8-Kuboktaeder mit nahezu planaren N4-Polygonen (siehe Struktur) bilden im Festkorper wie auch in Losung die Kerne der Dimerstrukturen bemerkenswert persistenter bishomoaromatischer Dianionen, die durch Reduktion von vororientierten Bisdiazenen mi

Synthetic details are presented for a series of more or less rigid, “parallel-in-plane” preoriented bis(diazenes), with N=N/N=N distances (d) of 3.3−2.9 A and interorbital angles (ψ) of 142−164° (X-ray crystal structures). DFT calculations

By oxidation of (presumably) bislithiated, unusually proximate, syn-periplanar bishydrazines an alternative access to σ-bishomoaromatic 4N/6e dianions is realized. Formal N-alkylation/arylation of these 4N/6e dianions leads to novel, cyclically delo

The recently proposed scheme of Grimme (BE scheme) (J. Am. Chem. Soc. 1996, 118, 1529) to calculate intrinsic bond energies (BE's) of hydrocarbons, which define seminal equilibrium quantities of chemical structures, is evaluated critically. CH and re

The viability of molecules with planar hexacoordinate carbon atoms is demonstrated by density-functional theory (DFT) calculations for CB 6 2– , a CB 6 H 2 isomer, and three C 3 B 4 minima. All of these species have six π electrons and are aromati

One- and two-electron oxidation of a caged, proximate, syn -periplanar bishydrazine leads to highly persistent, 4N/(7)6e (radical) cations—with dominant electron delocalisation along the cage bonds (CV, EPR, B3LYP). A NICS value of −20.6 is evide
