Abstract
Shortwave infrared (SWIR, 1000–1700 nm) absorbing and emitting dyes are needed for infrared diodes and sensors used in a wide variety of industrial and medical applications. Herein, an electron-withdrawing phosphine oxide (P═O) substituted xanthene is coupled with strong indolizine donors to produce a SWIR absorbing (λ abs = 1294 nm in DCM) and emitting (λ emis = 1450 nm in DCM) dye called PRos1450 . The unique properties of this dye are characterized via photophysical, electrochemical, and computational analyses.
