Heptamethine cyanine near-infrared fluorescent dye, preparation method therefor and use thereof

Abstract

The present disclosure provides a heptamethine cyanine near-infrared fluorescent dye, a preparation method therefor and use thereof, relating to the technical field of organic fluorescent molecules. The heptamethine cyanine near-infrared fluorescent dye has a structure as represented by following Formula I. The heptamethine cyanine near-infrared fluorescent dye provided by the present disclosure has better in vivo metabolic characteristic, no accumulation in normal tissues such as the liver, and a long time of tumor tissue developing window, is more suitable for precise diagnosis of tumors, has a certain clinical application prospect, and is applied to fluorescence development of clinical tumor and the like.
