Photo-irradiation is one of the most effective ways of introducing energy into a molecule with a great spatiotemporal resolution. From the photo-excited states, molecules relax via various pathways, which essentially converts photon energy to other forms including chemical and thermal energy. This thematic issue highlights the photochemical processes where some of the photon energy is stored within the molecule and can be potentially used at a later stage. Therefore, we seek to include all studies reporting processes involving:

1) light absorption on the molecular level (i.e., uptake of photon energy),
2) photochemical transformations of molecules, or
3) release of the stored energy.
