This work provides an overview of the recent advances in the field of two-photon absorbing
chromophores active in the short-wavelength infrared (SWIR) spectral range. Herein the …

Polymethine cyanine dyes, as the most important class of organic near-infrared-II (NIR-II)
fluorophores, recently received increasing attention due to their high molar extinction …

Organic dyes with absorption maxima in the second near-infrared window (NIR-II; 1000 to
1700 nm) are of great interest in biophotonics. However, because of the lack of appropriate …

Organic polymethine fluorophores with emission in the NIR-II window (1000–1700 nm) are
receiving enormous attention in biomolecular medicine and bioimaging, attributed to the …

Human attribution of absorption onset wavelength (λ onset) most often produces small, but
non-negligible errors in the attribution of this value tied to the optical energy gap. The …

A NIR II emissive dye was synthesized by the C–H bond functionalization of 1-methyl-2-
phenylindolizine with 3, 6-dibromoxanthene. The rhodindolizine (RhIndz) spirolactone …

Organic dyes that absorb and emit in the near-infrared (NIR) region are potentially
noninvasive, high-resolution, and rapid biological imaging materials. Indolizine donor-based …

Increased conversion of near-infrared (NIR) photons to electricity is needed to improve dye-
sensitized solar cells (DSCs). Here, we report two squaraine dyes (RR13 and RR14) with …

Shortwave infrared (SWIR)-emitting small molecules are desirable for biological imaging
applications. In this study, four novel pentamethine indolizine cyanine dyes were …

This study represents a successful approach toward employing polycaprolactone–
polyamidoamine (PCL–PAMAM) linear dendritic block copolymer (LDBC) nanoparticles as …
