A series of 1,8-naphthalimide-based fluorophores containing different chromophores with varying conjugation and electron richness at the imidic nitrogen atom are synthesized and characterized. These amine-functionalized naphthalimides are bipolar in nature and exhibit interesting optical and morphological variations attributable to the nature of the N substituents. Despite the fact that the dyes are structurally different owing to variation of the substituent on the imidic nitrogen atom, their electronic characteristics are similar and originate from the 4-aminonaphthalimide segment. Nevertheless, they exhibit variations in morphology in the microscopic domain, and this is attributable to structural differences. Further, these fluorescent dyes display biocompatibility and are used in the bioimaging of cells.

Intracellular pH plays a pivotal role in various biological processes. Herein, we adopted the through bond energy transfer (TBET) strategy to design a unique type of ratiometric two-photon fluorescent probe for imaging of lysosomal pH in live cells and tissues, termed Np-Rh-Lys. Specifically, a two-photon fluorophore (D-π-A-structured naphthalimide derivative) and a rhodamine B fluorophore were directly connected, and dimethylamino moiety served as a lysosomal targeting-group. The experiments demonstrate new probe Np-Rh-Lys was a reliable and specific probe for labeling lysosomes in living cells with two well-resolved emission peaks separated by 80 nm, and which showed high ratiometric imaging resolution and deep-tissue imaging depth over 180 μm, we thus may expect the new platform prompt the development of a wide variety of ratiometric two-photon fluorescent probes application in biological systems.

Ratiometric two-photon fluorescent probes can not only eliminate interferences from environmental factors but also achieve deep-tissue imaging with improved spatial localization. To quantitatively track Pd2 + in biosystems, herein, we reported
