In the first case, the details of network build-up and modification of network structure described above are not very important. The main aim of crosslinking is to keep the dendritic structures together permanently. Formation of three-dimensional nanostructures by metal-mediated self-assemblage can serve as an example Exo-tridentate tripyridyl compounds self-assemble upon treatment with (en)Pd(N03)2 [66]. 

When one of the dimensions of the material is in nanoscale, the material is known as a nanomaterial. Depending on the procedure for synthesis, the shape and size of the polymeric nanomaterial is altered. Hence the optimization process in the synthesis of any polymeric nanomaterial is critically important for its reproducibility. Various morphologies possessed by the electronically conducting polymeric nanomaterials are nanoparticles, thin films, nanotubes, nanorods, etc. Some special kinds of morphologies such as flower-like, dendritic, fibril-like, etc., are also foimd to exist. Some of the three-dimensional architectures contain the combination of various morphologies of the same polymeric material. The various structures are particularly important to their application. For example, for electrode purposes, the materials should have large surface area and hence three-dimensional nanostructures are preferred.
