発明の名称 (英語) Rhodamine-based colorant compound and process for producing same UPDATE
発明の概要(英語) wherein each of Q and Q1 represents C(R) or N; R represents a hydrogen atom, a halogen atom, an alkyl group having 1 to 6 carbon atoms, or a carboxyl group, where two Rs may bind to each other to form a ring; R1 represents a hydrogen atom, a halogen atom, an alkyl group having 1 to 6 carbon atoms, or a carboxyl group, where two R1s may bind to each other to form a ring; n represents a number of 0 to 3; and m represents a number of 0 to 3.
従来技術、競合技術の概要(英語) BACKGROUND ART
As a fluorescent colorant compound, various derivatives of rhodamine have been studied. In addition, as a compound prepared by condensing two rhodamine molecules, there has been known an aminobenzopyrano-xanthene colorant compound (Patent document 1). It is known that this aminobenzopyrano-xanthene compound exhibits three types of molecular structures which are a neutral form, a monocationic form and a dicationic form, depending on the hydrogen-ion concentration of a solution, and that each molecular structure leads to different absorption and emission properties (Non-patent document 1).
特許請求の範囲(英語) [claim1]
1. A compound represented by a general formula (1):
wherein Q represents C(R) or N; Q1 represents C(R1) or N; R represents a hydrogen atom, a halogen atom, an alkyl group having 1 to 6 carbon atoms, or a carboxyl group, where two Rs may bind to each other to form a ring; R1 represents a hydrogen atom, a halogen atom, an alkyl group having 1 to 6 carbon atoms, or a carboxyl group, where two R1s may bind to each other to form a ring; n represents a number of 0 to 3; and m represents a number of 0 to 3.

[claim2]
2. The compound according to claim 1, wherein Q and Q1 in the general formula (1) respectively represent C(R) and C(R1).

[claim3]
3. The compound according to claim 1, wherein each of Q and Q1 in the general formula (1) represents N.

[claim4]
4. A method for producing a compound represented by a general formula (6), comprising:
obtaining a compound represented by a general formula (5) by reacting 8-hydroxyjulolidine with a compound represented by a general formula (4); and
reacting the compound represented by the general formula (5) with hydroquinone in the presence of a condensing agent,
wherein Q represents C(R) or N; R represents a hydrogen atom, a halogen atom, an alkyl group having 1 to 6 carbon atoms, or a carboxyl group, where two Rs may bind to each other to form a ring; and n represents a number of 0 to 3.

[claim5]
5. A compound that exhibits different changes in hue, said compound represented by the following formula (1):
wherein Q represents C(R) or N; Q1 represents C(R1) or N; R represents a hydrogen atom, a halogen atom, an alkyl group having 1 to 6 carbon atoms, or a carboxyl group, where two Rs may bind to each other to form a ring; R1 represents a hydrogen atom, a halogen atom, an alkyl group having 1 to 6 carbon atoms, or a carboxyl group, where two R1s may bind to each other to form a ring; n represents a number of 0 to 3; and m represents a number of 0 to 3,
wherein the compound is in a neutral form, monocationic form or dicationic form, thereby to exhibit different changes in hue depending on in which form the compound is.

[claim6]
6. The compound according to claim 5, wherein the compound is used for detecting phenols and for fluorescence imaging.
