Angewandte Chemie, EarlyView.Der Einsatz von Dimesitylphosphid als höheres Homolog der etablierten Amidoliganden für Charge‐Transfer‐Kupfer(I)‐Komplexe führt zu einer Rotverschiebung der Emission um 3645 cm–1 in den rot‐orangen Spektralbereich im Festkörper sowie in den NIR‐Bereich in Lösung. Die thermisch‐aktivierte verzögerte Fluoreszenz weist hohe Dissymmetriefaktoren von glum =

A General Route to Bicyclo[1.1.1]pentanes through Photoredox Catalysis
ACS Catalysis, 2019 Photoredox catalysis has transformed the landscape of radical-based synthetic chemistry. Additions of radicals generated through photoredox catalysis to carbon–carbon π-bonds are well-established; however, this approach has yet to be applied to the ...

Health Hazard Manual for Firefighters [PDF]
, 1990 [Excerpt] Firefighters, as well as victims, can be exposed to a variety of toxic substances during a fire. Some of these toxicants are particularly insidious because they are produced by thermal decomposition before smoke makes a fire ...

Synthesis of Highly Cis, Syndiotactic Polymers via Ring-Opening Metathesis Polymerization Using Ruthenium Metathesis Catalysts [PDF]
, 2013 The first example of ruthenium-mediated ring-opening metathesis polymerization generating highly cis, highly tactic polymers is reported. While the cis content varied from 62 to >95% depending on the monomer structure, many of the polymers ...

Air quality in Mecca and surrounding holy places in Saudi Arabia during Hajj: initial survey. [PDF]
, 2014 The Arabian Peninsula experiences severe air pollution, the extent and sources of which are poorly documented. Each year in Saudi Arabia this situation is intensified during Hajj, the Holy Pilgrimage of Islam that draws millions of pilgrims to Mecca.

Angewandte Chemie International Edition, EarlyView.Dimesitylphosphide as a heavier congener of established amide ligands for charge‐transfer copper(I) complexes leads to bathochromic shift of the emission by up to 3645 cm−1 into the orange‐red (solid, polymer films) and even NIR (solution). The thermally activated delayed fluorescence exhibits high dissymmetry factors of glum = 10−2 in polystyrene.
