Abstract: An electro-polarizable compound has the following general formula: where Core1 is an aromatic polycyclic conjugated molecule having two-dimensional flat form and self-assembling by pi-pi stacking in a column-like supramolecule, which is tetrapirolic macro-cyclic fragment, R1 is an dopant group connected to Core1, m is number of R1 which is equal to 1, 2, 3 or 4, R2 is a substituent comprising one or more ionic groups, p is number of R2 which is equal to 0, 1, 2, 3 or 4. The fragment marked NLE containing the Core1 with at least one R1 has a nonlinear effect of polarization. Core2 is an electro-conductive oligomer self-assembling by pi-pi stacking in a column-like supramolecule, n is number of Core2 which is equal to 2, or 4, R3 is a substituent comprising one or more ionic groups, s is number of R3 which is equal to 0, 1, 2, 3 or 4. R4 is a non-polar resistive substituent, k is a number of R4 which is equal to 0, 1, 2, 3, 4, 5, 6, 7 or 8.

Abstract: The present disclosure provides an energy storage device comprising a first electrode, a second electrode, and a solid multilayer structure disposed between said first and second electrodes. The solid multilayer structure can be in contact with said first and second electrodes. The solid multilayer structure can include layers disposed parallel to said electrodes, the layers have a sequence (A-B)m-A, wherein, A is an insulating layer and B is a polarization layer comprising a colloidal composite with a micro-dispersion of electro-conductive nano-particles in an insulator matrix, and ‘m’ is a number greater than or equal to 1. Layer A can have a breakdown voltage of at least about 0.05 volts per nanometer (nm), and layer B can have a dielectric permittivity of at least about 100.
