ABSTRACT
Molecular engineering of near-infrared dyes: A new class of near-infrared fluorophores is reported that exhibit bright two-photon emissions, due to the resonant enhancement effect in the second absorption band of their two-photon absorption (2PA) spectra. Their Stokes shifts were increased by incorporating substitutes which experience slight rotations upon photoexcitation.
