A triply linked dicarbacorrole dimer (7) was synthesized from a new meso-meso singly linked dicarbacorrole dimer precursor (6) via an oxidative fusion reaction by 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) in the presence of trifluoromethanesulfonic acid (TfOH). Single crystal X-ray structure of 7 adopts a flat conformation with a length as ca. 15.946...

A thorough understanding of the internal conversion process between excited states is important for designing ideal multiple emissive materials. However, it is hard to experimentally measure both the energy barrier and energy gaps between the excited states of a compound. For a long time, it is dubious if what was measured is the energy gap or energy...

Lanthanide-doped scintillators have the ability to convert the absorbed X-ray irradiation into ultraviolet (UV), visible (Vis), or near-infrared (NIR) light. Lanthanide-doped scintillators with excellent persistent luminescence are emerging as a new class of persistent luminescent materials recently. They have attracted great attention due to their...

An azobenzene based Cu(I) metallocycle constituting the prototype for reversibly photoswitchable (3d<M-)metallocycles (i. e. without disassembly) is presented. Its ultrafast dynamics and the yield of the respective photostationary state reveal strong similarities with archetypical azobenzene. The unique combination of fs-TA and τ-PD elucidates...

This review completes a series of three articles which provide a comprehensive coverage of the structural chemistry of polynuclear titanium oxo compounds. The interplay of structure-influencing coordination characteristics of the ligands and preferred arrangement of the Ti/O polyhedra in the cluster cores is worked out. Abstract Homometallic...

The stereoselective construction of the anomeric bond has constituted one of the greatest challenges in modern organic chemistry. In recent years, examples of “bimodal” glycosyl donors have emerged, demonstrating excellent stereocontrol for both α- and β-anomers. This mini review explores the reactivity and scope of these donors and highlights how...
