具有规整共轭网络结构的二维高分子的合成

A honeycomb planar conjugated netpolymer (HPCNP) was first proposed. The theoretical calculation show that the palanar conjugated net polymer have high third-nonlinear optical susceptibility(near 107 a.u) and high Eg (7.2ev). The honeycomb cage (d=8 ?) in the molecular plane could storage metal atom and ion, so the proposed netpolymer could have potential applications in many areas. Because of the synthetic difficults, the total synthesis of such HPCNP netpolymer is now not realized. During the synthetic process sixteen useful intermedia were synthesized, some of them are not reported in the literature. A hyperbranched polymer consisting of bezene rings and m-position substituted ethenyls was also synthesized. After the treatment of the hyperbranched polymer with pulse laser light, a carbon nanostructure was find both in vapophase and matrix. This could be helpful for the understanding of the formation mechamism of such carbon nanostructures.
