Abstract
The morphology of fully and partially polymerized poly(phthalocyaninatogermoxane), left bracket Ge(Pc)O right bracket //n, crystals was studied by both scanning and transmission electron microscopy. It was found that the morphological units are lath-like crystals which aggregate into particles. Generally speaking, the thickness, width, and length of the laths are in the range of 1000-2000 A, 2000-10,000 A, and 1-5 mu m, respectively. Each lath may possess a mosaic substructure. Selected-area electron diffraction patterns indicate that the rigid, extended left bracket Ge(Pc)O right bracket //n chains are parallel to the large surface of the lath, and in most crystals the chains lie parallel to the lengthwise direction of the lath. However, in several cases, the chain orientation is at an angle of about 60 degree with respect to the long edge of the lath. The electron diffraction results are in accord with a tetragonal crystal structure (P4/m).
