A Mechanical Planar Chiral Rotaxane Induces Single‐Handed Helicity in a Twisted Perylene Diimide

Angewandte Chemie, EarlyView.
A mechanical planar chiral rotaxane (Rmp) is used to induce single‐handed helical chirality (M) in a perylene diimide chromophore, resulting in persistent circular dichroism (CD) and circularly polarised luminescence (CPL). ABSTRACT The twisting of chromophores such as perylene diimides (PDIs) into helical structures affords chiroptical properties from

Heterobimetallic Janus Catalysts for the One‐Pot Synthesis of Polar‐Apolar Block Copolymers

Angewandte Chemie, EarlyView.
Heterobimetallic Janus catalysts act as bifunctional initiators, combining two distinct polymerisation mechanisms in one pot to deliver well‐defined apolar‐polar block copolymers. Combining Earth abundant Ti and Al catalysts for respective α‐olefin and lactone polymerisation, the orthogonal activity is enabled by unprecedented initiation from a Ti ...

Divergent Synthesis of Möbius and Hückel N‐Heterocycloarenes From a Common Macrocyclic Backbone

Angewandte Chemie, EarlyView.
In the divergent synthesis of Möbius and Hückel N‐heterocycloarenes from a common macrocyclic precursor, the annulation reaction dictates topology: Scholl reaction gives Möbius topology, while InCl3‐mediated alkyne annulation gives Hückel topology. The Möbius N‐heterocycloarene is unevenly contorted as revealed by crystal structure, and the Hückel N ...
