As one reviewer said, 'The [2,1-c]IF isomer, the second most studied antiaromatic indenofluorene (IF), has been surprisingly overlooked'...and now, we (@sak71477) reviewed its various synthesis strategies in @Synthesis_1969 @thiemechemistry thieme-connect.com/products/…

Meet Prof. Subhajit Bandyopadhyay, the IISER Kolkata chemist who mentored India's Chemistry Olympiad team to its best-ever finish this July.
He studied at the University of Burdwan for his bachelor's, then IIT Kanpur for his master's, before earning his PhD under Prof. Reginald Mitchell at the University of Victoria in Canada. He went on to postdoc with Prof. Ron Breslow at Columbia University and spent a year at Cambridge under Prof. Florian Hollfelder before joining IISER Kolkata as an Assistant Professor.
Since then, he's picked up 4 Best Teacher Awards from IISER Kolkata's own student community, become a Fellow of the Royal Society of Chemistry, and earned an Honorary Membership of the American Chemical Society.
This July, as Head Mentor, he guided India's 4-student team through the 58th IChO in Tashkent, Uzbekistan. All 4 came home with gold. India tied for Rank 1 with China and Vietnam, its best result in 27 appearances at the competition.
Mentor who spent 27 years building the platform his students needed just 5 days in Tashkent to stand on.
Another Golden Sweep by India as our Chemistry team bags 4 Gold medals securing Rank #1 (jointly with China, Vietnam, and Individual Participant (Russia)) at the 58th International Chemistry Olympiad, Uzbekistan (icho2026.uz).

Lowering LUMO, reducing bandgap, and increasing aromaticity by modifying one of the substituents of a lesser-known pro-aromatic PAH, Fluorene-fused Phenalene, via a modular synthesis @ChemCommun 2026 Pioneering Investigator @sak71477 pubs.rsc.org/en/content/arti…
Following our N-annulated indenofluorene motif, we designed and synthesized N-annulated [5]helicene as another six-ringed azepine-fused polycycle, alongside its dibenzo-fused variant to serve as hole-transporting materials @JOC_OL #OrgLett @Hemonta29837649 pubs.acs.org/doi/10.1021/acs…
Azulene is an isomer of Naphthalene. Likewise, N-annulated Indenofluorene is just synthesized by @Hemonta29837649 as an isomer of the N-annulated Perylene for materials science: Synthesis, Properties, Antiaromaticity, and Charge-Transport #OrgLett @JOC_OL

Now published in Chem. Sci., 15 years of chemistry distilled down to 22 pages – quite possibly my group's magnum opus. Great job by Efrain, Gabby & Josh! Thanks to @Aromaticist, @JudyWuChem, Juan Casado, Carlos Gomez-Garcia and myriad other collaborators.
