The topochemical polymerization of monomers with conjugated triple bonds is an interesting example of the relationship between packing properties and reactivity in the solid state. For solid state polymer-izability the monomer molecules must be arranged in a herringbone-like structure according to Figure 1 so that only one nearest distance between the triple bonds of adjacent molecules of 3 to 4 A is affected. To... [Pg.271]

Macroscopic polymer single crystals with a high degree of perfection can be produced by the homogeneous topochemical polymerization of conjugated diacetylene monomers (1). The polydiacetylenes thus formed have a fully conjugated planar backbone and possess unusual optical and electronic properties... [Pg.230]

The substituted polydiacetylenes are another system forming an unique class of conjugated polymers. These macromolecules are obtained through a solid-state polymerization in the monomer crystal. The topochemical reaction is initiated either with... [Pg.230]
