We have recently discovered that a simple Pd2L4 cage system can manipulate the optoelectronic properties of quinone type guests:
Figure 1 (right). Crystal structure of quinone (orange) inside a Pd2L4 cage (green). Both absorption and emission properties of the guest inside the cage (ii) is different to either free guest (i) or cage only (iii).
This electronic perturbation of the guest lends itself to molecular activation, hence we are currently exploring various catalytic applications.
