Two types of epitaxial films of lutetium diphthalocyanine, LuPc2, have been obtained on KBr, LuPc2/KBr, and on the film of fluoro‐bridged aluminum phthalocyanine polymer, (AlPcF)n, on KBr, LuPc2/(AlPcF)n/KBr, by the molecular beam epitaxy technique. Their structures have been studied by transmission electron microscopy as well as scanning electron microscopy. The phase of LuPc2/KBr is bidirectionally oriented tetragonal, KBr(100)((10)1/2×(10)1/2)R±27°‐LuPc2. The phase of LuPc2/(AlPcF)n/KBr is predominantly unidirectionally oriented tetragonal, KBr(100)(3×3)R45°‐LuPc2/(AlPcF)n, but some bidirectional orthorhombic phase, KBr(100)C(6×3)R45°‐LuPc2/(AlPcF)n, is also present.
