Delighted to announce our new research published in #ChemEurJ —selected as a Hot Paper! This marks an important milestone as my first publication outside porphyrinoid chemistry. Together with Rio (PhD student), we've pioneered new insights into methine-bridged poly/oligothiophenes. (Open Access)

When Maika synthesized thienyl-substituted isophlorins for another purpose, she noticed they showed weaker antiaromaticity than others. This sparked our investigation into the relationship between substituents and antiaromaticity using both synthesis and computation. DOI: 10.1002/ajoc.202500372 (OA)

Starting today, my affiliation's English name changed: Osaka University → The University of Osaka (Japanese name remains unchanged:　大阪大学) www.osaka-u.ac.jp/en/guide/Our...

Effect of Chalcogen Interaction on the Structure of Methine-Bridged Trichalcogenophenes Authors: Rio Nishimura, Ken-ichi Yamashita DOI: 10.26434/chemrxiv-2025-2s0pv

Tuning Antiaromaticity through meso-Substituent Orientation in Core-Modified Isophlorins Authors: Maika Isoda, Haruna Sugimura, Yusuke Honda, Ken-ichi Yamashita DOI: 10.26434/chemrxiv-2025-nrvzb

Exciting new paper on an antiaromatic β-tetracyanoisophlorin! The Sn(IV) complex exhibits enhanced antiaromaticity compared to free base. Crystal structure revealed a surprising dianionic complex with axial anions, not the expected neutral complex. doi.org/10.1002/ajoc... (Open Access)

Sharing our previous work on metalloporphyrin hosts! While Zn porphyrins are conventionally chosen for axial coordination, we demonstrated successful binding with Ni and Cu porphyrins - metals typically known for their weak axial coordination ability. doi.org/10.1002/ajoc...

Surprised by the sudden follower growth - found out I'm in the Supramol Chem starter kit! Grateful and amazed to see so many supramolecular chemists here on Bluesky.

We've discovered other similar cyclization reactions and look forward to reporting them soon! During mechanism studies, this was my first experience using xtb/CREST/CENSO for conformational searching. Currently using this approach extensively with results coming soon!

Hello Bluesky! Excited to share that one of my research interests is antiaromaticity. We recently published our work on the synthesis of antiaromatic triphyrin via a serendipitously discovered 16π electrocyclization. doi.org/10.1002/chem... (Open Access)
