We have developed a groundbreaking chemical reaction using an N-heterocyclic carbene catalyst that has a low environmental impact to cleave the bond between the benzene ring of an aryl halide and a halogen atom to generate an aryl radical. Since aryl radicals can thus be easily generated from aryl halides that are widely used in organic synthesis, this is expected to be a powerful technology for precisely synthesizing medical and agricultural drugs and chemical materials.

Perovskite colloidal quantum dots (Pe-CQDs) are highly promising nanocrystals for optoelectronic applications. However, the size of the crystals should ideally be equal to ensure a consistent energy landscape. In a recent study, scientists clarified the relationship between differences in particle size—polydispersity—and the optoelectronic characteristics of Pe-CQDs. They showed that using equally sized, or ‘monodisperse,’ quantum dots results in markedly better performance in Pe-CQD solar cells, paving the way for future optoelectronic devices.
Selective Synthesis of Cyclo[9]pyrroles Based on an Oxidative Coupling
23 Jun 2021
A ring-expanded porphyrin with no meso-bridges comprised of an odd number of pyrroles was successfully synthesized via the oxidative coupling of the corresponding terpyrrole. This porphyrin showed a 34pi aromatic character and an intense absorption at the near-infrared region. We analyzed the optical and electronic structures using magnetic circular dichroism spectroscopy and time-dependent density functional theory calculations.

Researchers at Osaka Prefecture University have established an approach to identify the orientation of molecules and chemical bonds in crystalline organic-inorganic hybrid thin films deposited on substrates using Fourier transform infrared spectroscopy (FT-IR) and polarized infrared light with a 3D-printed attenuated total reflectance (ATR) unit. This inexpensive method with laboratory-grade equipment quickly reaches the crystal-structure model of even extremely thin films of less than 10 nm.

1,3-Diradicals Embedded in Curved Paraphenylene Units: Singlet versus Triplet State
09 Jun 2021
Chemical rings of carbon and hydrogen atoms curve to form relatively stable structures capable of conducting electricity and more — but how do these curved systems change when new components are introduced? Researchers based in Japan found that, with just a few sub-atomic additions, the properties can pivot to vary system states and behaviors, as demonstrated through a new synthesized chemical compound.

π-Extended Azacoronene with a Janus Double-Concave Structure
27 Apr 2021
A facile synthesis of two types of pyrrole-fused azacoronene with planar and double-concave π-structures was achieved. The two electron-rich azacoronenes were found to interact with electron-deficient π-electron compounds depending on their three-dimensional structures. Azacoronene with a curved structure was found to be less aromatic than those with a planar one based on macrocyclic π-conjugation.
Ultra-High Proton Conduction in Polyoxometalate-based Framework

Protons are the next big thing when it comes to fuel cell technology. The subatomic exchange produces power on a scale that challenges contemporary solid-state fuel cell technology, used to help power space shuttles. To realize the proton-based technology sooner, an international team of researchers have developed a hybrid material that effectively transports protons at high temperatures and humidity — two major challenges in past attempts.
