Abstract :
The development of new advanced materials require the combination of different properties within the same material.1,2 Combining porosity and magnetic ordering in a single material presents a significant challenge since magnetic exchange generally requires short bridges between the spin carriers, whereas porosity usually relies on the use of long diamagnetic connecting ligands or linkers. Despite this apparent incompatibility, notable successes have been achieved by rational design and fine tuning of crystal engineering in generating magnetic sponges which could be used as sensors for different gases.3 Sensing of ubiquitous gases with marginal differences in size, such as nitrogen and oxygen,4 also carbon dioxide sensing by magnetic sponge5 will be discussed in the talk.
