発明の名称 (英語) Photoacid generator
発明の概要(英語) (US7550246)
A photoacid generator comprising a metal hydride complex represented by the formula (I): wherein X represents a metal atom.
The iridium hydride complex of the present invention can be used as an acid generator for chemically-amplified photoresists or color filters for liquid crystal, and in addition, can be widely applied in photographic-related or printing-related fields, or the like.
特許請求の範囲(英語) [claim1]
1. A method for generating an acid, said method comprising: (a) providing a metal hydride complex of the following formula (I) dissolved in a solution consisting essentially of a solvent
wherein X represents a metal atom; and
(b) exciting the metal hydride complex by irradiating the complex with a laser beam until deprotonation of the metal hydride complex takes place; thereby
(c) producing an acidic solution.
[claim2]
2. The method for generating acid of claim 1 wherein the metal hydride complex is dissolved in an organic solvent.
[claim3]
3. The method for generating an acid of claim 1, wherein the metal hydride complex is dissolved in water.
[claim4]
4. The method for generating an acid of claim 1, wherein the metal atom is iridium.
[claim5]
5. The method for generating acid of claim 1, wherein the metal atom is ruthenium.
[claim6]
6. The method for generating an acid of claim 1, wherein the metal atom is rhodium.
[claim7]
7. The method for generating acid of claim 1, wherein the metal atom is cobalt.
[claim8]
8. The method for generating an acid of claim 2, wherein the organic solvent is one or more of acetonitrile, a primary, secondary or tertiary alcohol, a polyhydric alcohol, dimethyl formamide, dimethyl sulfoxide and ethyl acetate.
[claim9]
9. A method for generating an acid for a chemically-amplified photoresist or a color filter for liquid crystals, said method comprising: (a) providing a metal hydride complex of formula (I) dissolved in a solution consisting essentially of a solvent
wherein X represents a metal atom; and
(b) exciting the metal hydride complex by irradiating the complex with a laser beam until deprotonation of the metal hydride complex takes place; thereby
