A Donor‐Acceptor‐Type Two‐Dimensional Poly(arylene vinylene) for Efficient Electron Transport and Sensitive Chemiresistors

Angewandte Chemie International Edition, Accepted Article.
Vinylene‐linked robust 2D conjugated covalent organic frameworks (2D c‐COFs), i.e., layered 2D poly(arylene vinylene)s (2D PAVs), are emerging as promising polymer semiconductors for electronics and photocatalysis. However, achieving narrow optical band gaps and efficient electron transport remains a significant challenge for this class of materials to

Controlled Growth of Oligophenylene‐Structures on Graphene for Facile Secondary functionalization.

Angewandte Chemie International Edition, Accepted Article.
Functionalization of graphene derivatives is a common approach to tune material properties for use in various applications. Due to the low reactivity of the unsaturated carbon lattice of graphene, not only are few chemical approaches suitable for successful functionalization, such as those involving highly reactive in situ formed radical species or ...

A Joyful Journey: Tungsten(VI) and Tungsten(V) Fluorides Meet N‐Heterocyclic Carbenes and Cyclic (Alkyl)(amino)carbenes

Angewandte Chemie International Edition, Accepted Article.
The first complexation of tungsten(VI) fluoride with N‐heterocyclic carbenes (NHCs) and a cyclic (alkyl)(amino) carbene (cAACMe) is reported, which led to the complexes [(NHC)WF6] (NHC = IiPrMe, 1; BIiPr, 2; IMes, 3; IDipp, 4; and SIDipp, 5) and [(cAACMe)WF₆] 6. Solid‐state structural analysis reveals distorted mono‐capped trigonal prismatic geometries

Influence of Ligand Design and Non‐Covalent Interactions on the Isoselective Ring‐Opening Polymerization of rac‐ß‐Butyrolactone using Salan and Salalen Rare‐Earth Metal Catalysts

Angewandte Chemie International Edition, Accepted Article.
We herein report the influence of the ligand framework on the isoselective ring‐opening polymerization (ROP) of rac‐β‐butyrolactone using highly active in situ generated salan [ONNO]H2 and salalen [ONNO]H rare‐earth metal complexes. The stereochemistry was found to be highly dependent on the ortho‐substituents, enabling the synthesis of either ...
