We are hiring, two fully funded MSc/PhD positions available.
Please share! #Chemsky #Pisky

Interested in non-functional organic magnetic switches?

We actually do want to make them work — that’s why we study the ones that don’t, so we can make them function :-)

Thanks for the funding! 😁

Fluoranthene-Containing Distorted Nanographenes Exhibiting Two-Photon Absorption Response Two distorted nanographenes combining helicenes and a fluoranthene unit within their polycyclic scaffolds were synthesized. Their structural and electronic properties were elucidated by various spectr...

Delighted to share the work of John Bergner about the influence of fluoranthene in the TPA response of ribbon-shape nanographenes! 😊 Huge congratulation to the team at Kivala Group, Campaña Lab and Ermelinda Maçôas. Beautiful work! 👏

Allenes as Stimuli-Responsive Chromophores for Visible to Near-Infrared Optical Modulation Despite their rigid, orthogonal π-systems and synthetic modularity, allenes remain underexplored in functional material design. Here, we report that tetraaryl-substituted allenes undergo clean and rev...

Super stoked about our second JACS! We establish allenes as reversible halochromes with dramatic optical property switching. This work could not have been this successful without the amazing support from @minjungson.bsky.social at BU and the Ding Lab at WFU. Check it out

From Aqua Green to Deep Red in One Step: Targeted Design of a Highly Luminescent Phosphacyclic Vat Orange 3 Dye Silver-mediated phosphacyclic ring expansion with strategic placement of phosphorus and dimethyl acetylenedicarboxylate (DMAD) on Vat Orange 3 was carried out. The target compounds possess narrow HOMO...

London Dispersion as a Design Element in Molecular Catalysis This Perspective describes the role of London dispersion (LD) interactions as a key factor controlling chemical selectivity. LD arises from the correlated motion of electrons, leading to subtle yet si...

Very interesting perspective from Schreiner. #pisky #chemsky

A Supramolecular Nanosheet Assembled from Carpyridines and Water The use of water as a solvent to facilitate supramolecular self-assembly and polymerization is well-documented; however, it is rare that water acts as a monomer that undergoes polymerization. We repor...

Water impacts self-assembly. But what changes really?
In our latest @jacs.acspublications.org at 🇨🇭UNIGE, we ferret out vastly different organisations in wet vs dry solvents that lead to identical macrostructures

Our new preprint introduces a new approach for controlling the helicity and handedness of polyaromatics using a helical cyclophane synthon: isobenzofuranophane.
We demonstrate the applicability by remotely controlling the handedness and pitch of [5]helicenes. go.shr.lc/44yCyln

Osmium ensnared in a hydrocarbon ring Chemists make new class of planar organometallic compounds

An ABSOLUTELY spectacular structure by the Xia group at SUSTECH. Haiping & his team have been working on enveloping the metal with a fully conjugated carbon ring for over a decade, and they finally succeeded! This warms my reformed metallabenzene chemist's heart!

Solution-phase synthesis of Clar’s goblet and elucidation of its spin properties - Nature Chemistry In 1972, Erich Clar envisioned Clar’s goblet, a polycyclic aromatic hydrocarbon featuring two unpaired electrons that are spin-paired. However, synthesizing it in a solution phase remains challenging....
