TLDR
The observed photoinduced phase transition was found to be mediated by photogeneration of charge carriers (and not of excitons) and the extremely high efficiency is perhaps due to cooperative interaction between the locally photoconverted domains.Abstract:
It was observed that bi-directional phase changes can be triggered by genuine photoexcitation between two phases with different bond structures in polydiacetylenes The observed photoinduced phase transition was found to be mediated by photogeneration of charge carriers (and not of excitons) The extremely high efficiency is perhaps due to cooperative interaction between the locally photoconverted domainsread more

Control of magnetic properties through external stimuli.
TL;DR: Most of the Review is devoted to the properties of valence-tautomeric compounds, molecular magnets, and spin-crossover complexes, which could find future application in memory devices or optical switches.

Crystalline networks with unusual predicted mechanical and thermal properties
TL;DR: In this article, the authors present molecular-mechanics calculations for some hypothetical phases of carbon which exhibit both kinds of behaviour, namely negative thermal expansion and low-temperature polymorphism.
