Nuclear magnetic resonance spectroscopy and mass spectrometry, among other techniques have been used in work on polymer pores. While, irradiation with light is a wel-established approach to the initiation of polymerization as well as cross-linking (or curing of polymers) during plastics production, researchers in the USA have now demonstrated that light can be used to retroactively increase the size of the pores within a polymer network.

Photosynth Res. 2011 Aug 13;
Authors: Pandit A, de Groot HJ
This short review describes how solid-state NMR has provided a mechanistic and electronic picture of pigment-protein and pigment-pigment interactions in photosynthetic antenna complexes. NMR results on purple bacterial antenna complexes show how the packing of the protein and the pigments inside the light-harvesting oligomers induces mutual...
