**•** Doping with nanoobjects significantly influences the photorefractive properties of nano‐ bjects-doped organic matrices. An increase in the electron affinity (cf. shungite, fullerenes, QDs) and specific area (cf. QDs, CNTs, nanofilers) implies a dominant role of the intermo‐ lecular processes leading to an increase in the dipole moment, local polarizability (per

**•** The variations of the length, of the surface energy, of the angle of nanoobject orientation relative to the intramolecular donor fragment of matrix organics can significantly change the pathway of charge carrier transfer, which will lead to changes in the electric field gra‐

Thus, analysis of the obtained results leads to the following conclusions:
