Abstract
Electrowetting apparatus including a compound comprising a plurality of colorant moieties and a linker. The plurality of colorant moieties includes a first colorant moiety having a first net dipole and a second colorant moiety having a second net dipole, wherein the plurality of colorant moieties are linked by and disposed around the linker so that the first net dipole and the second net dipole at least partially cancel each other.
Claims25
Electrowetting apparatus comprising a compound which is a dye comprising:
- a plurality of colorant moieties comprising:
- a first colorant moiety having a first net dipole, and
- a second colorant moiety having a second net dipole,
- wherein at least one of the plurality of colorant moieties is of a dye class selected from the group consisting of:
- an azo dye having the general formula:
- a bisazo dye having the general formula:
- an anthraquinone dye having the general formula:
- a coumarine dye having the general formula:
- a naphthaquinone dye having the general formula:
- a squaraine dye having the general formula:
- a stilbene dye having the general formula:
- and
- an indophenol dye having the general formula:
- wherein each of A1 to A64 is independently selected from the group consisting of:
- a linker, hydrogen (H), an alkyl group having at least one carbon atom, an alkyl group having 1 to 32 carbon atoms, a halogen atom, an alkyl group, an alkenyl group, an oxo group, an alkoxy group, a thiol group, a hydroxyl group, a thioalkyl group, an aryl group, a heteroaryl group, an amine group, a nitro group, a cyano group, an amide group, a sulphonyl group, a carboxy group, and a trifluoromethyl group;
- and
- a linker, the plurality of colorant moieties linked by and disposed around the linker so that the first net dipole and the second net dipole at least partially cancel each other.
