Growth of cobalt-phthalocyanine on KCl(001) substrate and copper-phthalocyanine whisker

Cobalt-phthalocyanine (Cope) was grown on a KCl {001} substrate and on a copper-phthalocyanine (CuPc) whisker which was epitaxially grown on a KCl {001} substrate. Crystallization was carried out by a repeated vacuum deposition and thermal treatment method. CoPc whiskers were grown on a KCl {001}-cleaved substrate. A CoPc whisker with a smaller diameter was also grown on the CuPc whisker. The epitaxial growth of CoPc on CuPc was confirmed using high-resolution electron microscopy and transmission electron diffraction analysis.
