Title: Rhodol fluorophores for near-infrared imaging

Abstract

The present disclosure encompasses embodiments of a novel near-infrared-emitting molecular fluorophore and probes incorporating said fluorophore advantageous for in vitro and in vivo research studies. The fluorophore is robust, photostable, and possesses functionalities for easy bioorthogonal conjugation (e.g., click chemistry, hydrazone formation, Diels Alder, Staudinger ligation, etc.). It is biocompatible and emits at 711 nm in aqueous conditions. These fluorophores may be used to fluorescently tag biological molecules or structures of interest, or used as optical reporters (i.e., activatable molecular probes, fluorescent dyes) for specific biomarkers/analytes as they can be switched from “off” to “on.” This fluorophore is useful for cellular assays and preclinical small animal imaging as the near-infrared emission is highly penetrating, and the photophysical properties are outstanding. As such, the properties of this class of fluorophores could easily be translated for use in clinical applications.
