Near Infrared Dyes

"There is a pressing need for the identification of newer,
more effective dyes that absorb and emit in the NIR region"

Conformationally Restricted Aza-Bodipy: A Highly Fluorescent, Stable, Near-Infrared-Absorbing Dye, Angewante Chemie International Edition Volume 44, Issue 11 , Pages 1677 - 1679 Weili Zhao, Dr., Erick M. Carreira, Prof. Dr.

NIR (Near InfraRed Dyes) 700-1100 nm are useful as biological sensors because of low background absorption, low scattering and cheap illumination sources. This paper describes the synthesis of a boron based dye but does not yet have a hook to attach another moiety. The criterion for success is based on a simple spectroscopic measurement.
