Different procedures for preparing columnar stacks and layered structu
res from phthalocyanine molecules are presented and discussed, includi
ng organization of the molecules by one of the following means: (i) wi
th the help of liquid crystallinity, (ii) by using crown ether rings a
ttached to the phthalocyanine core, (iii) by polymerization, and (iv)
by Langmuir-Blodgett film formation.
