InSe[CS(NH2)2[C14H10]] clathrate is a 2D hierarchical structure of the subhosthostguest type obtained by the intercalation method under the influence of light. In this case, we used a layered InSe single crystal as a semiconductor 2D matrix, thiourea (CS(NH2)2) functioned as a supramolecular cavitand, and anthracene (C14H10) as a photoelectret. We used illumination during synthesis for the photoelectret polarization of anthracene. The impedance spectroscopy method was used to study the conductive and polarization properties of InSe[CS(NH2)2[C14H10]] clathrate. As a result, the manifestation of photoinduced quantum capacitance was recorded, the nature of which is associated with the discretization of the energy spectrum and finite tunneling times. The results obtained from the study of the thermally stimulated discharge spectra show that InSe[CS(NH2)2[C14H10]] clathrate is characterized by homo-charge relaxation and broad bands with a quasi-continuous spectrum of localized states. The behavior of the current-voltage characteristics indicates the manifestation of photocurrent with a value of + 23.5 mV.
