Deuteration of heptamethine cyanine dyes enhances their emission efficacy


Janeková, Hana; Friedman, Hannah C; Russo, Marina; Zyberaj, Mergime; Ahmed, Tasnim; Hua, Ash Sueh; Sica, Anthony V; Caram, Justin R; Stacko, Peter (2024). Deuteration of heptamethine cyanine dyes enhances their emission efficacy. Chemical Communications, 60(8):1000-1003.

Abstract

The design of bright short-wave infrared fluorophores remains a grand challenge. Here we investigate the impact of deuteration on the properties in a series of heptamethine dyes, the absorption of which spans near-infrared and SWIR regions. We demonstrate that it is a generally applicable strategy that leads to enhanced quantum yields of fluorescence, longer-lived singlet excited states and suppressed rates of non-radiative deactivation processes.
