Synthetic example 1
[0760]Synthesis Example 1 Synthesis of Intermediate (Compound 2)
[0761]In a round bottom flask equipped with a stirring device, 2.0 g (3.9 mmol) of rhodamine B (compound 1: manufactured by Wako Pure Chemical Industries, Ltd.) and 2.7 g (3.9 mmol) of tetrakis (pentafluorophenyl) boron were added (IV) Lithium salt (LiFABA) (manufactured by Tosoh Finechem Co., Ltd.) and 30 ml of dichloromethane were reacted at 25°C for 1 hour. After the reaction solution was diluted with dichloromethane, it was washed with water. The solvent was distilled off from the reaction solution by concentration under reduced pressure to obtain 4.1 g of a purple solid carboxylic acid body (compound 2) having tetrakis(pentafluorophenyl)boron (IV) anion (the yield was 100%).

[0763]Example 1 Synthesis of polyfunctional polymeric dye (Compound 4)
[0764]In a round-bottom flask equipped with a stirring device, 4.4 g (3.9 mmol) of the intermediate (compound 2) obtained in Synthesis Example 1 and 30 ml of dichloromethane were added to dissolve, and 2.4 g (4.7 mmol) of pentaerythritol was added. Acrylate {Compound 3: Trade name Light Acrylate PE-3A (Compound 3 content is 60.0%), manufactured by Kyoeisha Chemical Co., Ltd.}, 0.1g (1.2mmol) of 4-dimethyl 4-dimethylaminopyridine (DMAP) (manufactured by Wako Pure Chemical Industries, Ltd.) and 1.3 g (6.7 mmol) of 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide salt The salt (1-ethyl-3-(3-dimethylaminopropyl)carbodiimide, WSC) (manufactured by Toyobo Co., Ltd.) was reacted at 25°C for 3 hours. The reaction liquid was washed with water, and the solvent was distilled off from the reaction liquid by concentration under reduced pressure to obtain a purple-red solid. The solid was purified by a silica gel column to obtain...

[0766]Example 2 Synthesis of Multifunctional Polymeric Dye (Compound 6)
[0767]In a round bottom flask equipped with a stirring device, 8.8 g (7.9 mmol) of the intermediate (compound 2) obtained in Synthesis Example 1 and 60 ml of dichloromethane were added to dissolve, and 12.4 g (9.4 mmol) of dipentaerythritol was added Pentaacrylate {Compound 5: Trade name NK ester A-9550 (Compound 5 content is 40.0%), manufactured by Shinnakamura Chemical Industry Co., Ltd.}, 0.3 g (2.4 mmol) of DMAP (Wako Pure Chemical Industries Co., Ltd.) (Manufactured by) and 2.6 g (13.4 mmol) of WSC (manufactured by Toyobo Co., Ltd.), and reacted at 25°C for 3 hours. The reaction liquid was washed with water, and the solvent was distilled off from the reaction liquid by concentration under reduced pressure to obtain a purple-red solid. 1300ml of methanol was added to the solid to dissolve it, 300ml of water was slowly added dropwise to crystallize, and the solvent was distilled off by concentration under redu...
