What is it about?
Dyes included in porous matrices are interesting materials for technological applications. For example, they can be used in solar cells, drug delivery, diagnostics, and optical devices. Studying their behaviour at high pressure would be important to extend their application range beyond normal conditions, but this has never been done, so far. Here, we choose a dye, we put it inside a zeolite - a porous container with channels of molecular size - and see how the material reacts to extreme compression by using both experiments and computer simulations.
Why is it important?
Apparently, our main result seems quite boring: we push the resistance of the material to its limit, and nothing happens. At high pressure, the arrangement of the dyes inside the pores is preserved, and the interactions governing the stability of the material become stronger. We are very happy about this, because it means that our material can withstand huge stresses without undergoing deformations and losing functionality.
