Thiol-Yne click chemistry of acetylene-enabled macrocyclization
Nature Communications, 2022 Thiol–yne coupling is a reliable method to link two molecular units, but has not been extensively explored for the construction of macrocycles. Here, the authors use gaseous acetylene, the simplest alkyne unit, to synthesize a variety of macrocycles ...

Phenyl-Linked Anthracene-Based Macrocycles with Geometrically Tunable Optical Properties
Organic Materials, 2020 Anthracene has been widely explored because of its intrinsic photophysical and photochemical properties. Here, two novel anthracene-based macrocycles (1 and 2) were designed and synthesized with para- and meta-phenylene spacers.

Chemically Fueled Systems Chemistry Across Length Scales
Advanced Functional Materials, EarlyView.Chemically fueled reaction cycles regulate processes through single and multiple catalytic sites on the molecular and assembly scale. This gives rise to unique kinetically controlled properties/functions like spatio‐temporal catalysis, oscillations, optical properties, and perform work.

Angewandte Chemie, EarlyView.Directional control within the secondary coordination sphere redefines CO2 reduction by iron porphyrins. Simply rearranging identical urea hydrogen‐bond donors modulates reactivity, revealing that optimal catalysis does not only arise from maximal intermediate stabilization, but also from directional, adaptive non‐covalent interactions that balance ...

Advanced Healthcare Materials, EarlyView.Under NIR irradiation, PTCPP generates ROS to eliminate MRSA biofilms and promote M1 macrophage polarization for phagocytosis. After bacterial clearance, the material is phagocytosed by macrophages, shifting their polarization to M2 phenotype via metabolic reprogramming, which synergistically enhances anti‐infection therapy and wound healing.

Synthesis and Screening of A DNA-Encoded Library of Non-Peptidic Macrocycles [PDF]
, 2020 There is considerable interest in the development of libraries of non-peptidic macrocycles as a source of ligands for difficult targets. We report here the solid-phase synthesis of a DNA-encoded library of several hundred thousand thioether-linked ...

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
