Abstract

Hyperbranched structures containing pyrrole units were obtained from ortho-, meta- and para-diaminodiphenyldiacetylenes as AB2 type monomers by one-step polymerization.

The para-hyperbranched compound was observed by optical microscopy and scanning electron microscopy.

Microscopy studies identify two phases. The first is the insoluble one which gives origin to flake type structures. The second is acetone soluble phase, which generated crystalline structure manifesting in optic anisotropy and rhomboids and triangles dendrimeric structures.
