Molecular Engineering of NIR‐II Fluorophores for Improved Biomedical Detection

Lei, Zuhai, Zhang, Fan·2021·Angewandte Chemie International Edition

Abstract

The development of fluorophores for the second near‐infrared window (NIR‐II, 1000–1700 nm) represents an emerging, significant, and vibrant field in analytic chemistry, chemical biology, and biomedical engineering. The wavelength, brightness, and stability are three crucial factors that determine the performance of an NIR‐II fluorophore. Up to now, significant progress has been made in the development of NIR‐II fluorescence molecular probes, including the synthesis of D‐A‐D and D‐π‐A fluorophores with improved NIR‐II fluorescence imaging performance and the construction of off–on probes and ratiometric probes via energy transfer or molecular structure modification. In this review, we summarize the most recent advances in molecular engineering design strategies of NIR‐II fluorophores and probes, then highlight a selection of bioimaging and biosensing applications. We also provide perspectives on potential challenges and opportunities in this emerging field

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
