Dear Dr @vonderleyen, head of States @EUCouncil, @EU_Commission, @Europarl_EN 60 scientists from 17 different countries, including 7 Nobel Laureates urge you to reconsider the cuts to the Horizon Europe! Everyone who supports this: please SIGN at rescue-horizon-europe.org

@ralvarezyebra @NOAH_ITN Yes, fullerene might be interesting. Thanks for your answers, and once again great work :)

@amyedo1 @NOAH_ITN As you said, the planarity of the guest seems to be an important factor for the pi-pi interactions with the host and the curvature of corannulene playing against that factor. Maybe something bigger than corannulene, such fullerene could be an interesting guest.

Hey supramolecular chemists! Check out our contribution to #SupraChemDay entitle "A flexible self-folding receptor for coronene" and the MDs attached bellow!!! @NOAH_ITN #supramolecular #chemistry

@ralvarezyebra @NOAH_ITN Ah interesting, thanks. I wonder if you used a bowl shaped aromatic like corannulene, if you would have similar binding to coronene. How important is the planarity of your guest? From the 2nd gif, it looks it might be key for the pi-pi interactions, but is that the case?

@amyedo1 @NOAH_ITN Thanks! We have tried all these compounds (PAHs) but only Coronene and MeNDi bound to the cavitand. Some of these are meant to focus on the length rather than the width it seems that is not the most important factor. May be wiht longer ones..

@ilsemanet @CMozaceanu @NOAH_ITN @Heitz_group Hi Ilse, the quenching is due to electron transfer between the porphyrin and acridinium (both tweezer 1 & 3 are non-fluorescent). So it is unrelated to bpy. I hope this answers your questions.

@amyedo1 @CMozaceanu @NOAH_ITN @Heitz_group What is the reason of the quenching in 3? What happens to the fluorescence in the presence of bpy?

Happy #SupraChemDay and hello to all the scientists! Here's my poster on our "8-State Porphyrin-Acridinium Multi-stimuli Responsive Nanoreceptor" Looking forward to all your comments and questions 😊 #supramolecular #chemistry @NOAH_ITN @Heitz_group

@QBVBouvier @NOAH_ITN Thanks 👍

@amyedo1 @NOAH_ITN Hi Amy. For the stability, the longer the better, of course. I would say that the microcapsules have to be stable for, at least, a few months. Otherwise, those microcapsules would not be of great interest to the polyurethane market.

Glad to share my poster for the 2nd edition of the Supramolecular Chemistry Day: Microencapsulation of liquid polyisocyanates #SupraChemDay @NOAH_ITN

@CMozaceanu @NOAH_ITN @Heitz_group Thanks Cristina & great question! We're actually able to switch on/off the tweezer's fluorescence by switching between the Acr and Acr-OH species (3 is not fluorescent but 7 is). So any application where you would want to switch on/off visualisation of the tweezer/guest binding.

@amyedo1 @NOAH_ITN @Heitz_group Interesting work @amyedo1! I am fascinated by your representation of all equilibrium species! So both Acr and Acr-OH species can bind the guest (with similar Ka). Is there an application where you could use the switching property? Why 3 would be better than 7, for example?

@AgnieszkaSzumna @NOAH_ITN @Heitz_group Thanks Agnieszka! We have a mix of the cis & trans isomers (~80% trans), and have not been able to separate them (via column). But the stereochemistry doesn't affect the binding properties of the molecule.

@amyedo1 @NOAH_ITN @Heitz_group Very nice, complex switching system Amy. I have a question concerning stereochemistry of the double bond in the linker. Do you have a defined stereochemistry or use a mixture of isomers in further studies. How about separation?
