摘要：
Most [2+2] photodimerization reactions proceed heterogeneously. At a small conversion phase separation leads to the destruction of the parent crystal. The crystal fragmentation can be avoided by irradiation in the long wavelength tail of the absorption. The intermediate mixed crystalline states as well as thermally reversible systems have been studied.
