Preparation method and application of heptamethine benzo indole cyanine dye

The invention discloses a preparation method and application of a heptamethine benzo indole cyanine dye, and belongs to the field of polymethine indole cyanine dyes and preparation thereof. The methodcomprises the following steps: 1) carrying out a heating reaction on raw materials containing a 2,3,3-trimethyl-4,5-benzoindole derivative and a nucleophilic substituted compound under a vacuum condition to obtain an organic ammonium salt; and 2) carrying out a heating reaction on a solution containing the organic ammonium salt obtained in the step 1) and a cycloalkene derivative under a closed condition, wherein the structural formula of the heptamethine benzo indole cyanine dye is represented by a formula (I). According to the invention, the dye has near-infrared light absorption and fluorescence development performances and can be used as a probe auxiliary agent; and the method has the advantages of short synthesis route, environment-friendly solvent, simple process, avoidance of noblemetal catalysis, high yield, high product purity and the like, is high in applicability, and can be used for synthesizing products of various structure types.
