Described herein are new silicone-based compounds that have short wavelength infrared (SWIR) absorption and emission. The silicone-based compounds are readily accessible and obtainable on large scale with high purity through simple purification procedures. In one aspect, the silicone-based compounds have an absorption extending into the SWIR region and an emission maximum in the SWIR region which is promising for biological imaging applications.

Silicone-based dyes with short wavelength infrared absorption and emission and methods for making and using the same

In one aspect, the disclosure relates to fluorescent dyes that absorb and emit in the near infrared II (NIR II) range of the electromagnetic spectrum, methods of making same, compositions comprising same and methods of using the compositions to perform imaging on biological samples, and optoelectronic devices using the dyes. The dyes are small organic molecules that are inexpensive and facile to produce, can be water-soluble, have tunable properties, and are biocompatible and/or possess low toxicity.

Design, synthesis, and photophysical properties of a novel NIR II dye for biological imaging and optoelectronic devices

Provided herein are dyes, dye-sensitized solar cells, and sequential series multijunction dye-sensitized solar cell devices. The dyes include an electron deficient acceptor moiety, a medium electron density ?-bridge moiety, and an electron rich donor moiety comprising a biaryl, a substituted biaryl, or an R1, R2, R3 substituted phenyl where each of R1, R2, and R3 independently comprises H, aryl, multiaryl, alkyl substituted aryl, alkoxy substituted aryl, alkyl substituted multiaryl, alkoxy substituted multiaryl, OR4, N(R5)2, or a combination thereof; each R4 independently comprises H, alkyl, aryl, alkyl substituted aryl, alkoxy substituted aryl, or a combination thereof; and each R5 independently comprises aryl, multiaryl, alkyl substituted aryl, alkoxy substituted aryl, alkyl substituted multiaryl, alkoxy substituted multiaryl, or a combination thereof. The solar cells include a glass substrate, a dye-sensitized active layer, and a redox shuttle. The devices include at least two dye-sensitized solar cells connected in series.
