Thank you so much 🥳

Exactly!! only acetic acid

Yes, of course. It was our first move! As you could see in the graphs, a higher adsorption efficiency is observed in hydrogel form for both COFs and drugs. This phenomenon is due to the hierarchical porosity that presents the gel.

The amount of water is also very important, as it makes the reaction more reversible, and the crystallinity is achived. In this case, acetic acid itself contains traces of water.

Yes, I pre-dissolve both building blocks in acetic acid, which acts as a catalyst and solvent for the reaction. Then, adding one on top of the other instantly forms a gel. A period of crystallization is necessary to obtain the intrinsic crystallinity of COFs

Maybe I can help you with this... My group uses a supercritical CO2 drying method to remove solvent molecules from gels, so you can calculate the yield and perform the characterization with your dried gel. This is one of the articles that talks about it: DOI: 10.1002/anie.202100881.

Oh! Nice! Thank you for the explanation, it’s clearer to me now. Hope the best for you in your research! 🤞🏽

Thanks for your support! 😇 Our hypothesis is that bromine induce new hydrophobic interactions between brominated COFs and drugs, but we are currently working on theoretical calculations to test this idea 🕵🏽‍♀️

Lovely poster! Experimental work is noticeable! I may be wrong but I would expect that the higher the specific surface area of the MOF is, the higher the catalytic activity, and in this case it is the other way around, is it due to the properties of Ga?

Good to hear this!

I love the poster! Very clear for me! I have some curiosities about it like the yield in the synthesis of the metallogel? And how are you going to proceed to isolate porous MOF in porous phase?

Wish you luck with this! , it is always a tough work to move from lab scale to industry💪🏼

Such a great recyclability result!
June 17, 2025 at 12:36 PM
I get it! Thank you very much and good luck with the project!

Nice poster! It’s not my field and people working in computational chemistry may be from another world! So, I can’t help you much, but I have some curiosities: can this model be generalized to other Zr-based MOFs? How computationally expensive is your model compared to traditional force fields?

Very interesting work! My group is also focused on wastewater treatment with reticular frameworks materials! So, I have some questions looking at your poster: how many adsorption/desorption cycles are Al/Zn-BMOF Nano-rods capable of? How could it be implemented in the industry?
