near infrared emissive materials with highquantumyields is an important challenge. Several classes of squaraine dyes have demonstrated highquantumyields, but require significantly red-shifted absorptions to access the NIR window. Additionally, squaraine dyes have typically shown narrow Stokes shifts, which limits their use in living biological imaging applications due to dye emission interference

Molecular engineering strategies designed to red-shift cyaninedye absorptions and emissions further into the near-infrared (NIR) spectral region are explored. Through the use of a novel donor group, indolizine, with varying cyanine bridge lengths, dye absorptions and emissions, were shifted deeper into the NIR region than common indoline-cyanines. Stokes shifts resulting from intramolecular steric

indolizine-based chromophores (MPI-1)-OT-TCF and (MPI-3)-OT-TCF with octatetraene π-bridge and tricyanofuran acceptor moieties have been synthesized and systematically investigated. Chromophores exist as a mixture of E- and Z-isomers in low-polar dioxane and chloroform solutions, while in polar solvents only one isomer is observed. The chromophores show excellent thermal stability with Td>260 °C (DSC) and

group in nonlinearoptical (NLO) chromophores, we have designed and synthesized newpush-pull chromophores (MPI-1)-V-TCF and (MPI-3)-V-TCF, having isomeric 3(1)-methyl-2-phenylindolizin-1(3)-yl (MPI-1(3)) electron donor and TCF acceptor, and compared them with dimethyl aniline (DMA) analogues. The Uv-Vis (linear optical) properties and solvatochromic behavior were also investigated; theoretical predictions
