Carbonyl azetidine substituted naphthalimide fluorescent dye as well as synthesis method and application thereof
-
Paragraph 0073-0077, (2021/06/13)
The invention provides a novel carbonyl azetidine substituted naphthalimide fluorescent dye as well as synthesis and application thereof. The dye takes 1, 8-naphthalimide as a fluorophore parent, and the fourth site of the 1, 8-naphthalimide is covalently connected with carbonyl azetidine. The novel fluorescent dye has excellent fluorescence intensity and light stability, so that the novel fluorescent dye has wide application prospects in the fields of fluorescence detection, fluorescence imaging and the like, especially in the emerging fields of single molecule detection, super-resolution fluorescence imaging and the like. R1 is H, C1-4 alkyl and aryl, R2 is shown in the specification, and in R2, X1 is H, C1-2 alkyl, X2 is C1-2 alkyl or shown in the specification, X3 is C1-2 alkyl or shown in the specification, and X4 is C1-2 alkyl.
Carbonyl azetidine substituted NBD fluorescent dye as well as synthesis method and application thereof
-
Paragraph 0047-0051, (2021/06/12)
The invention provides a novel carbonyl azetidine substituted NBD fluorescent dye as well as synthesis and application thereof. The structure of the dye is characterized in that carbonyl azetidine is covalently connected to the fourth site of a 4-chloro-7-nitrobenzene-2-oxa-1, 3-diazole (NBD) parent. The novel fluorescent dye has excellent fluorescence intensity and light stability, so that the novel fluorescent dye has wide application prospects in the fields of fluorescence detection, fluorescence imaging and the like, especially in the emerging fields of single molecule detection, super-resolution fluorescence imaging and the like. R1 is as described in the specification, X1 is H or C1-2 alkyl, X2 is C1-2 alkyl or as described in the specification, x3 is C1-2 alkyl or as described in the specification, and X4 is C1-2 alkyl.
