Abstract: PURPOSE: To obtain a display which changes in colors in a wide range and is bright with small consumption of electric power without any limit of the observation angle by using an electrochemical color-changing cell having a specified inner-molecule charge transfer salt as a color-changing agent for a display panel. CONSTITUTION: This electrochemical color-changing cell consists of a cell 2 at least a part of which is transparent and is filled with a color-changing agent 4 comprising an inner-molecule charge transfer salt of a soln. in a liquid, gel or solid phase. The cell has an indicating electrode 6 and a counter electrode 8 which face each other with a separation zone 12 between these and are connected to a variable DC power supply 10. The material 4 consists of a covalent compd. having at least one radical cationic part which makes a covalent bond with at least one radical anionic part or a material containing carbonyl groups which make conjugates with violene or cyanine part or aromatic part. In the obtd. color-changing cell, changes in colors in a wide range can be obtd. by changing the voltage applied on electrodes 6, 8.

Abstract: Derivatives of compounds containing a carbonyl group conjugated to an aromatic moiety and methods of fabrication thereof consisting of a thioether, an ester, an ether, a phosphate and a silylether. Electrons are supplied to the carbonyl group conjugated to an aromatic moiety to form a reduced material. The reduced material is contacted with an electrophile which attacks and chemically combines with the carbonyl group conjugated to an aromatic moiety. The parent material can be regenerated by hydrolysis of the derivative. A silyl derivative can be selectively formed on a polyimide material surface which can act as a barrier to an RIE etch of the polyimide material. After etch the polyimide material is regenerated from the silyl derivative.
