Abstract:
It is shown that the process of light-induced resistive switching in films based on macroheterocyclic dyes correlates with the spatial localization of molecular orbitals (center or periphery in a coordination compound). External-illumination-induced spatial redistribution of charges can both promote the formation of a conducting state and prevent its formation. The transition from solution to a film in samples under study occurs without a significant distortion of the energy spectrum of molecules; for this reason, numerical methods of calculation of orbitals in isolated molecules can be applied to films. The prediction of the response of a system to an external action significantly simplifies the choice of materials with desired properties for practical applications.
