The rapidly growing interest in synthesising 2D Janus materials is supported by the numerous theoretical predictions of the unique properties of this material category. Here, we report the discovery of the novel 2D Janus material RhSeCl which crystallises in a space lattice with hexagonal symmetry P63mc with the unit cell parameters a = 3.48760(10)...

Lithium-rich antiperovskite cathode materials with cationic and anionic redox bi-functionality are promising candidates for lithium-ion batteries (LIB) with high energy density. Here, we report the synthesis of antiperovskite (Li2Fe)SeO by means of an one-step solid-state method which results in phase pure material consisting of predominantly micro...

Many of the solid-state materials needed for today's technologies are based on homoanionic compounds, e.g. chalcogenides or halides. In recent years, far-reaching modifications of these compounds were achieved only by varying the cations, while the influence of exchanged anions, in particular the combination of different anions, has seldom been inv...

Solid solutions of 2D transition metal trihalides are rapidly growing in interest for the search for new 2D materials with novel properties at nanoscale dimensions. In this regard, we present a synthesis method for the Cr1-xRuxCl3 solid solution and describe the behaviour of the unit cell parameters over the whole composition range, which in genera...

The development of electrode materials with multielectron redox functionality is imperative for next-generation Li-ion batteries with a high gravimetric capacity. Within this context, a Li-rich (Li 2 Fe)SO antiperovskite cathode is a promising candidate exhibiting such multielectron cationic and anionic redox features, resulting in a reversible ext...

A series of solid solutions (Li2Fe1-yMn y )SO with a cubic antiperovskite structure was successfully synthesized. The composition (Li2Fe0.5Mn0.5)SO was intensively studied as a cathode in Li-ion batteries showing a reversible specific capacity of 120 mA h g-1 and almost a 100% Coulombic efficiency after 50 cycles at 0.1C meaning extraction/insertio...

A series of heteroquinoid merocyanine dyes with an extended π‐system as well as lower homologues (bearing varied donor units such as benzothiazolylidene and 4H‐pyran‐4‐ylidene) were synthesized. We have investigated the thermal, optical and electrochemical properties of the compounds. The dyes exhibit a variety of features that are desirable for so...

Near infrared absorber materials for organic solar cells are needed to cover larger parts of the solar spectrum and, therefore, achieve higher short circuit current densities. We present a push-pull chromophore with a quinoid merocyanine structure (QM1) as donor material in vacuum deposited organic solar cells with a thin film absorption up to 1100...
