Globally Aromatic 10-Boratetraoxacorroles: Boron-Doped Macrocyclic Chromophores with Intense Red-to-Near-Infrared Emission

Jonas Fehler, Lukas Swoboda, Alexandra Friedrich, Vivien Schütz et autres

Neutral, globally aromatic boron-containing macrocycles are exceptionally rare, with the 10-bora-21,22,23,24-tetraoxacorroles reported herein representing only the second class of such compounds known to date, following the 5-bora-21,22-dioxaporphyrin we recently described, and are also the first neutral, globally aromatic boracorroles. Here, we present …

Nickel(0)‐Catalyzed [2+2+2] Cycloadditions of Linked Bisdiynes with Diaryl Alkynes Generates D‐π‐A‐π‐D Bis(arylethynyl)indane‐Based Organic Frameworks as Noncytotoxic Probes for Ds‐DNA/Ds‐RNA

Robert Ricker, Dijana Pavlović Saftić, Sabine Lorenzen, Johannes Schneider et autres

Nickel(0)‐catalyzed [2 + 2 + 2] cycloadditions of linked bisdiynes with diarylacetylenes were performed using the Ni(II) precursor complex [(TMEDA)Ni( o ‐tolyl)Cl] in the presence of PPh 3 ligands to generate the active Ni(0) species. Optimal reactivity was observed when electron‐rich bisdiynes …

Merging Pyrrole with Boron into Versatile Di(2‐pyrryl)borane Building Blocks: π‐Extension, Polymerization, and Coordination

Daniel Göbel, Andreas Helbig, Alexandra Friedrich, Jonas Bachmann et autres

Conjugated di(hetaryl)boranes-particularly those of thiophene, but also of furan-have recently proven to be extremely useful building blocks for organic optoelectronic materials. The importance of the combination of boron with pyrrole, on the other hand, becomes particularly apparent when considering the well-known, versatile …

We investigate six novel D:A cocrystals of dibenzotetrathiafulvalene (DBTTF) and 1,4,5,8,9,11-hexaazatriphenylenehexacarbo-nitrile (HATCN), prepared via solvent evaporation, yielding …

Poly( p ‐phenylene phosphaborene): A Modified Poly( p ‐phenylene vinylene) with π‐Conjugated B═P Linkages

Julian Glock, Jonas Klopf, Merian Crumbach, Johannes Chorbacher et autres

Abstract While the isoelectronic substitution of selected C═C by B═N units in π‐conjugated organic compounds has evolved into a well‐established concept to create novel hybrid materials with modified properties, the use of valence isoelectronic B═P units for such purposes has been hardly …

Understanding Twisted Triarylboranes from Single Crystals to Heterojunction Blends and Their Applications in Organic Photovoltaics

Jianhua Han, Xu Han, Anirudh Sharma, Jesika Asatryan et autres

The triarylborane family has expanded rapidly as valuable π electron-accepting moieties in organic materials, yet the performance and application of triarylboranes in organic photovoltaics (OPVs) have thus far been limited. Herein, we present a comprehensive platform of 17 distinct triarylboranes to investigate …

BNB-Modified Perylene, Terrylene, and Quaterrylene Diimides: Introduction of the π-Accepting and Aggregation-Suppressing Diborinic Imide Group in Rylene Dyes

Michael Müller, Jonas Klopf, Alexandra Friedrich, S Lutz et autres

Rylene diimides are among the most intensively researched classes of functional organic dyes. They are characterized by outstanding photoabsorption and -emission properties in combination with excellent photostability and thermal stability. Due to strong intermolecular π–π interactions, the larger, peri -extended rylene diimides, …
