An electro-polarizable compound has the following general formula: n nCore1 is an aromatic polycyclic conjugated molecule having two-dimensional flat form and self-assembling by pi-pi stacking in a column-like supramolecule, R1 is a dopant group connected to Core1; a number m of R1 groups is 1, 2, 3 or 4. R2 is a substituent comprising one or more ionic groups connected to Core1; a number p of ionic groups R2 is 0, 1, 2, 3 or 4. The fragment marked NLE has a nonlinear polarization effect. Core2 is an electro-conductive oligomer self-assembling by pi-pi stacking in a column-like supramolecule, a number n of such oligomers is 0, 2, or 4. R3 is a substituent comprising one or more ionic groups connected to Core2; a number s of the ionic groups R3 is 0, 1, 2, 3 or 4. R4 is a resistive substituent providing solubility of the compound in a solvent and electrically insulating the column-like supramolecules from each other. A number k of substituents R4 is 0, 1, 2, 3, 4, 5, 6, 7 or 8. |
