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

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...

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...

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...

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

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...

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...

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

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...

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....

Triisopropylsilyl-(TIPS)-alkynylated phenazinothiadiazoles were prepared by the condensation of halogenated ortho-quinones and TIPS-alkynylated...

To achieve a highly symmetric triptycene based hexamethoxytriphenylene in high yield of 97 %, a less symmetric triptycene (C3v) is necessary as precursor for...

The 1,4-dithiin motif is known for its reversible redox properties to generate radical cations and diradical dications and thus is interesting for organic electronic...
