Ordered monolayers → multilayers of trivalent metal phthalocyanines, C60, and the perylenetetracarboxylic dianhydride (PTCDA) have been formed by molecular beam epitaxy processes on both single crystal MoS2 and SnS2, and on MBE-deposited SnS2 thin films. The bulk packing structures for the trivalent metal chloride phthalocyanines lend themselves to layered growth during deposition, as do the structures for C60 and PTCDA. RHEED data collected during the formation of [(InPc-Cl)1-4 ML/(C60)1-4 ML]1-20/SnS2/mica multilayers suggests that the structures observed during the formation of single component thin films can be sustained during multilayer formation, up to several lattice periods. Absorbance spectra of Pc/C60 and Pc/PTCDA multilayers show Pc Q-bands with maxima and full widths consistent with the formation of ordered Pc layers, provided that the Pc layer thickness is kept at 1-2 monolayers throughout the formation of the multilayer assembly.
