Structural changes to metallosupramolecular assemblies resulting in the release or uptake of guests are well established whereas transformations turning on and off specific self‐recognition are far less developed. We report a novel ligand (2,6‐bis(1‐(3‐pyridin‐4‐yl)phenyl‐1H‐1,2,3‐triazol‐4‐yl)pyridine) possessing a tridentate central metal‐binding...

The concept of Secondary Building Units (SBUs) is central to all science on metal‐organic frameworks (MOFs), and it is widely used to design new MOF materials. However, the presence of SBUs during MOF formation remains controversial, and the formation mechanism of MOFs remains unclear due to limited information about the evolution of prenucleation cluster...

Oligo‐S,S‐dioxothienylenevinylenes have been prepared by transferring oxygens to the sulfur atoms using the HOF•CH3CN complex. Their photophysical properteis are presented in comparison with their thiophenevinylene congeners together with their vibrational properties and molecular force fields permiting the interpretation of the alteration of aromaticity...

“The high crystallinity of these materials allows for a direct visualization of the mechanisms governing the host–guest interactions.” Read more about the story behind the cover in the Cover Profile and about the research itself on page ▪▪ ff. (DOI: 10.1002/chem.201803547). Abstract Invited for the cover of this issue are the groups of Emilio...

We demonstrate single‐molecule imaging of metal‐ion induced double‐stranded DNA formation in DNA nanostructures. The formation of the metal ion‐mediated base pairing in a DNA origami frame was examined using C‐Ag‐C and T‐Hg‐T metallo base pairs. The target DNA strands containing consecutive C or T were incorporated into the DNA frame, and the binding...

1,3a,6a‐Triazapentalene (TAP) is a compact fluorescent molecule consisting of a triazabicyclo[3.3.0]octane skeleton. In this work, a method of synthesizing a directly connected TAP ring system as a linearly bonded aromatic system with a planar form was established. The TAP‐bonded system showed interesting fluorescence properties resulting from...
