Tellurophene‐Induced Triplet–Singlet Spin‐Flip Acceleration: An Advanced Design for Narrowband Organoboron Emitters with Fast Reverse Intersystem Crossing

Angewandte Chemie, Volume 138, Issue 14, 27 March 2026.
Linking an auxiliary dibenzo[b,d]tellurophene unit markedly accelerates exciton spin conversion in multi‐resonance‐type thermally activated delayed fluorescence emitters. Owing to the heavy‐atom effect of tellurium, the corresponding OLEDs retain remarkably high external electroluminescence quantum efficiencies exceeding 25% even at an exceptionally ...

Iso‐Tellurazole N‐Oxides Assemble Adaptively Folded Macrocyclic Dodecamers

Chemistry – A European Journal, EarlyView.
Te…O Chalcogen bonding links twelve molecules into a ring that wraps itself around molecular guests. ABSTRACT Self‐assembled macrocyclic dodecamers were found in the crystals of new pseudo‐polymorphs of iso‐tellurazole N‐oxides. These structures are formed by molecules connected by NTe…O chalcogen bonds and are folded in a pattern that defines 89–153 ...

Copolymer Synthesis of N‐Vinylacetamide and 2‐Methylene‐1,3‐Dioxepane Provides a New Degradable Polymer

Journal of Polymer Science, Volume 63, Issue 6, Page 1306-1318, 15 March 2025.
ABSTRACT N‐vinylamides, especially noncyclic N‐vinylacetamide (NVA), have been used in various applications such as biomaterials, surfactants, and hydrogels. However, their potential to copolymerize with cyclic ketene acetal (CKA) to create degradable polymers is underexplored.

Sulfur‐ and Selenium‐Decorated Coumarins: Synthetic Strategies Involving Cyclization and Late‐Stage Functionalization

The Chemical Record, EarlyView.
Two decades of synthetic strategies for sulfur‐, selenium‐decorated coumarins are critically surveyed through 44 literature reports, with particular emphasis on derivatives functionalized at the C‐3 and C‐4 positions. This review reports the direct construction of the coumarin framework through cyclization processes and late‐stage functionalization of ...

Diphenyl Ditelluride Intoxication Triggers Histological Changes in Liver, Kidney, and Lung of Mice

Analytical Cellular Pathology, 2015
Tellurium compounds may be cytotoxic to different cells types. Thus, this work evaluated the effect of diphenyl ditelluride ((PhTe)2), an organotellurium commonly used in organic synthesis, on the morphology of liver, kidney, and lung.

Diorganotelluride···N Chalcogen Bonds: Analysis and Tuning of Two σ‐Holes

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Two new chalcogen bond aggregates were analyzed using single crystal X‐ray diffraction: an oligomeric ChB aggregate between bis(pentafluorophenyl) telluride and DABCO, and a monoadduct between (pentafluorophenyl)(phenyl) telluride and quinuclidine. In addition to some of the shortest intermolecular Te···N contacts reported, these structures provide ...
