Film aggregate having electricity conducting characteristics. The film is comprised of a substantially inert support surface carrying one or several monomolecular film layers formed by a surface active material of liquid crystal type having modifiable electrical properties. The film layer is of a sandwich type construction containing at least the folllowing zones: - a spacer-zone (2) containing aliphatic hydrocarbyl groups and which to its electrical characteristics is substantially inert, - a conducting area (3-5) which on the one hand is comprised of a charge-transfer zone (3 or 5) and on the otherhand of a polarizable zone (5 or 3) as well as of a spacer zone (4) between these zones, - a spacer zone (6) which corresponds to the above zone (2), - a hydrophilic zone (7). The invention concerns also new glycerophospholipids and threitolphospholipids to be used in the films, containing in their fatty side chains at least one, but preferably two active groups, i.e. a polarizable group and charge-transfer group. The invention also concerns the fatty acids, alcohols group and amines used for the side chains in the lipids and carrying a polarizable group and a charge-transfer group. |
