Our work in @J_A_C_S tackles a long-standing puzzle in nucleic acid photophysics: long-lived excited states in pyrimidine nucleobases. We show the intermediate is a metastable ground-state species with a twisted C=C bond, not an excited state! pubs.acs.org/doi/10.1021/ja…

Happy to share our recent accounts in Accounts of Chemical Research, summarizing my PhD works. Thanks @prof_amitava for this opportunity and your kind guidance. @AmerChemSociety @patra_group @iacskolkata pubs.acs.org/doi/10.1021/ac…

@Ayan_Nation1st Congratulations @Ayan_Nation1st Sir.

@prof_amitava @patra_group @JPhysChem (7/7) Special Note: Although the work was already done a few years back, I could enrich the work with some DFT calculations that I learned during my Postdoc, which, although very simple, gives me the satisfaction of learning and implementing new things.

Interested in BODIPY dyes and their aqueous aggregates? Check our recent work. Sincere thanks to @prof_amitava @patra_group for his valuable guidance and @JPhysChem for giving us the opportunity to publish this work. Check comment(s) for details. pubs.acs.org/doi/10.1021/ac…

@prof_amitava @patra_group @JPhysChem (6/7) My sincere thanks to Prof. Patra for his valuable guidance and for giving me the opportunity to publish this work. Thanks to Dr. Mula from BARC, India and Dr. Biswas from Weizmann Institute, Israel for this awesome collaboration.

@prof_amitava @patra_group @JPhysChem (5/7) Thorough ultrafast spectroscopic investigation suggests prominent features of these aqueous aggregates that will be helpful in biophotonics and photocatalytic applications in the future.

@prof_amitava @patra_group @JPhysChem (4/7) Also, we reported highly Stokes-shifted emission from aqueous BODIPY H-aggregates (which are usually non-emissive) due to their special herringbone close-packing structure.

@prof_amitava @patra_group @JPhysChem (3/7) This work is significant as we identified unusual "red-shifted H-aggregates" for the first time for BODIPYs.

@prof_amitava @patra_group @JPhysChem (2/7) We have shown how the close-packing structure controls the aggregation behavior and eventually the excited state dynamics of these BODIPY aggregates.

@prof_amitava @patra_group @JPhysChem (1/7) In this work we synthesized a series of BODIPY dyes, reported their crystal structures, and elucidated the detailed ultrafast excited state dynamics of these molecules and their aqueous aggregates.

@IndiaPostOffice my article number EW447541217IN is dispatched from KOL AP TMO on 5/1 and not delivered yet. Is it a joke? It contains important documents. Why are you calling your service 'speed post' when you are unable to deliver in time? Please update the status immediately.

@IndiaPostOffice worst service provided by you. My urgent article EW447541217IN is stuck at KOL AP TMO for 5 days. It says item dispatched but not received at all. Very poor service by the organisation . Please deliver it immediately and update me the status.

@Indranarayan01 Thank you

@Ghoshsrijon @patra_group @JPhysChem Congratulations Srijon!

Our latest work is now out in the Journal of Physical Chemistry C, which elucidates the energy and charge transfer dynamics in an oligothiophene-squaraine hybrid aggregate to generate a charge-separated state that lives over 8 ns. @patra_group @JPhysChem pubs.acs.org/doi/10.1021/ac…

@pramodpillai81 @ACSCatalysis @Indranarayan01 @Mr_Lumens Many many congratulations @Indranarayan01

Our work on 'photocatalytic olefination with quantum dots' is now published in @ACSCatalysis. A great effort by @Indranarayan01 to showcase the power of 'quantum dot photocatalysis' in synthetic organic chemistry. Congratulations to Indra & @Mr_Lumens pubs.acs.org/doi/10.1021/ac…
