Abstract
Polymeric materials made of polyalkynes [-C≡C-]n have long been known to exhibit delocalized π-electron systems. However. these materials normally are insoluble and hence of little practical use as nonlinear optical materials. We have prepared a series of polyalkynes which incorporate side chains, typically attached to a metal atom such as Pt. causing the polymer to be readily soluble. The rigid-rod geometry of ordinary polyalkynes is preserved in this arrangement due to the square planar coordination of the metal atom. The thermal stability (decomposition temperature and Tg) measurements and the third-order nonlinear susceptibilities determined at 1064 nm are presented.
