Buchwald‐Hartwig coupling of a triisopropylsilyl (TIPS)‐ethynylated dibromo‐N,N'‐dihydrotetraazapentacene with 1,4‐bis(TIPS‐ethynyl)‐2,3‐diaminonaphthalene furnishes a...

An increasing number of organic light-emitting diodes (OLEDs) is nowadays based on the use of polymers as the emissive material. For this material class in particular,...

The transition-metal catalyzed cyclization of bissilylethynylated N,N’-dihydro¬tetra¬aza¬pentacene (TIPS-TAP-H2) into bissilylated cyclo¬penta¬[fg,qr]¬pentacenes is reported....

A corpus consisting of high-quality human annotations of missing and implied information in argumentative texts (English version). The data is further annotated with semantic...

Cata-condensed heteroannulated tetraarenocoronenes with C2h symmetry have been obtained from three doubly brominated diarenoperylenes. X-ray diffraction showed that the...

A series of quinoxalinophenanthrophenazines (QPPs) with two-dimensional triptycene end-caps was synthesized from a triphenylene base ortho-diamine. UV/vis spectroscopy suggested...

In this thesis, the first chiral polycyclic aromatic hydrocarbon (PAH) with a monkey saddle topology is presented. Starting from a truxene building block that is readily...

This repository contains our path generation framework Co-NNECT, in which we combine two models for establishing knowledge relations and paths between concepts from sentences,...

Tetraiodotetraazapentacene I4TAP , the last missing derivative in the series of halogenated silylated tetraazapentacenes, was synthesized via condensation chemistry from a...

Introduction. Since its introduction in the DSM-5 and the ICD-11, the construct of personality functioning has received increased research interest. Recent studies have shown...

Long-lasting pain stimuli can trigger maladaptive changes in the spinal cord, reminiscent of plasticity associated with memory formation. Metabolic coupling between astrocytes...

The solvent and catalyst free thermolysis of biphenylenes at 350 °C furnishes [n]cyclo-ortho-phenylenes ([n]COPs, n=4–10) in one step and in high yields. At 400 °C biphenylene...

Macromolecules with complex, defined structures exist in nature but rarely is this degree of control afforded in synthetic macromolecules. Sequence-defined approaches provide a...

The application of a new class of fluorophores based on a twisted tetraazaperylene core in the fabrication of emissive organic 3D microstructures has been investigated. The...

Das Nördlinger Ries weist bereits am Beginn der Jungsteinzeit um 5400 v.Chr. mit 16 nachgewiesenen Fundplätzen eine dichte Besiedlung auf. Zudem liegt dort mit dem Fundplatz...

The current gold standard of auricular reconstruction involves a highly time-consuming manual graft assembly from autologous costal cartilage. The intervention may require...

Spin-orbit coupling in the electronic states of solution-processed hybrid metal halide perovskites forms complex spin-textures in the band structures and allows for optical...

We investigate intramolecular singlet fission (iSF) of spiro-linked azaacene heterodimers by time-resolved spectroscopy and quantum chemical calculations. Combining two...

This dataset contains whole-rock geochemical and mineral chemical data for ultrapotassic volcanic rocks of the Efogi Volcanic Field, Papua New Guinea. Abstract: Continental...

Molecular double helices are ubiquitous in nature and have also been generated artificially. These are usually based on helical ribbons. Here, a new type of double helices based...
