The principle underlying antiaromaticity

open access: yes, 2019
Aromaticity is one of the most widely used chemical concepts. Current definitions are purely phenomenological and relate symmetry, reactive stability and the occurence of molecular diamagnetic response currents.

Stable Ultrabroad‐Absorbing Radical Achieves Efficient NIR‐II Photothermal Conversion via Facile Synthesis

open access: yesAdvanced Science, Volume 12, Issue 43, November 20, 2025.
A new and stable open‐shell acceptor–donor–acceptor type radical EDOT‐TPAO4 with electronic conductivity of 0.02 S cm−1 is prepared by one‐step with high yield and exhibited unexpected photothermal conversion as one of the best pure organic materials.

A New Family of Jumonji C Domain-Containing KDM Inhibitors Inspired by Natural Product Purpurogallin

open access: yesFrontiers in Chemistry, 2020
Aberrant epigenetic modifications are involved in cancer development. Jumonji C domain-containing histone lysine demethylases (KDMs) are found mainly up-regulated in breast, prostate, and colon cancer.

Recent Developments in Organic Radical Inclusion in MOFs and Radical MOFs

open access: yesChemistryOpen, Volume 14, Issue 11, November 2025.
Inclusion of organic radicals in porous materials offers an opportunity to tailor properties that include stability of radicals, conductivity, sensing, and catalysis. Similarly, radical metal‐organic frameworks (MOFs) are synthesised to enhance or create such properties.

Metalloporphyrin/Phthalocyanine Catalysts for Electrocatalytic Nitrogen Fixation

open access: yesAdvanced Science, Volume 12, Issue 40, October 27, 2025.
This review focuses on the application of metal porphyrin/phthalocyanine‐based catalysts in electrocatalytic nitrogen fixation. The detailed examination encompasses the structure and modification strategies of metal porphyrin/phthalocyanine‐based catalysts, their application in electrocatalytic nitrogen fixation, and the associated reaction mechanisms.

Negative Refraction Induced by M\"obius Topology

open access: yes, 2016
We theoretically show the negative refraction existing in M\"{o}bius molecules. The negative refractive index is induced by the non-trivial topology of the molecules.

The Green’s function for the Hückel (tight binding) model [PDF]

open access: yes, 2018
Applications of the Huckel (tight binding) model are ubiquitous in quantum chemistry and solid state physics. The matrix representation of this model is isomorphic to an unoriented vertex adjacency matrix of a bipartite graph, which is also the Laplacian

Aromaticity and Photoreactivity of 4‐ and 3‐Nitrenopyridine 1‐Oxides and Phenylnitrene

open access: yesJournal of Physical Organic Chemistry, Volume 38, Issue 10, October 2025.
NICS(1.7)zz, ACID, and spin density calculations reveal that triplet 4‐nitrenopyridine oxide, 3‐nitrenopyridine oxide, and phenylnitrene display Baird triplet aromaticity. These findings help clarify the relationships between structure and aromaticity in triplet arylnitrenes. ABSTRACT The pursuit of sustainable organic synthesis has renewed interest in
