SCSC Reactivity by Modifying Experimental Conditions

In addition to the synthetic methods described above, two physical methods directed towards facilitating SCSC reactivity involving the [2+2] photodimerization 

A more recent method of inducing SCSC [2+2] photoreactivity involves the use of crystals of nanometer-scale dimensions [70]. The method has been successful for the construction of polymers of 2,5-distyrylpyrazine, as well as methyl p-phenylene-diacrylate. Presumably, the nanoscopic crystal size provides the reactant crystals with enough flexibility to withstand strain induced by the photopolymerization process.
