This relates to a dye represented by Formulae II and IIA below:
wherein;
R1 represents a hydrogen, an aryl group containing 6 to 14 carbon atoms, or an alkyl group containing 1 to 12 carbon atoms;
R2 and R3 together form an aromatic, carbocyclic or heterocyclic ring system containing 6 to 14 atoms;
X represents a sulfoxide (S=O), sulfone (SO2), or dicyanovinyl (C(CN)2) group;
Y represents a sulfoxide (S=O), sulfone (SO2), carbonyl (C=O) or dicyanovinyl (C(CN)2) group;
L1, L2, and L3 represent methine groups, wherein the methine groups may combine to form a 5- or 6-membered ring when m is equal to or >1;
m is 0, 1, 2, or 3;
W is an aryl group; and
D is a moiety in conjugation with the X and Y groups.
这涉及到下式 II 和 IIA 所代表的染料:
其中
R1 代表氢、含 6 至 14 个碳原子的芳基或含 1 至 12 个碳原子的烷基;
R2 和 R3 共同形成含 6 至 14 个原子的芳环、碳环或杂环系统;
X 代表亚砜(S=O)、砜(SO2)或二氰基乙烯基(C(CN)2);
Y 代表亚砜 (S=O)、砜 (SO2)、羰基 (C=O) 或双氰基乙烯基 (C(CN)2) 基团;
L1、L2 和 L3 代表甲基,其中当 m 等于或大于 1 时,甲基可结合形成 5 或 6 元环;
m 为 0、1、2 或 3;
W 是芳基;以及
D 是与 X 和 Y 基团共轭的分子。
