Oriented films of poly (dimethylsilane) (PDMS) and poly (diethylsilane) (PDES) on smooth quartz plates were prepared by the friction deposition technique. The oriented film of poly (dihexylsilane) (PDHS) spin–cast from its n–hexane solution on the oriented film of PDMS. In the same way, the oriented film of soluble poly (methylpropylsilane) (PMPrS) spin–cast from its n–hexane solution on the oriented film of PDES. The bilayer films were studied with polarized UV absorption spectroscopy to confirm the molecular orientation and indicated that solution–cast films and friction–transferred films of polysilanes were oriented. The intermolecular energy transfer was studied in the bilayer films of polysilanes with polarized fluorescence spectroscopy. The results indicated that in bilayer films the energy transfer occurs from PDMS layer to PDHS layer and also from PMPrS layer to PDES layer.<\div>
