Dicyanostilbene-derived two-photon fluorescence dyes with large two-photon absorption cross sections

Four dicyanostilbene-derived two-photon fluorescence (TPF) dyes were synthesized as the model compounds to systematically study the effect of the dicyano and the terminal substituent on the two-photon absorption (TPA). These four compounds (DSO, DCY, DTO and DPH) exhibit very large two-photon absorption cross sections (δ). DCY (A-π-A) with the terminal cyano group has especially high fluorescence quantum yield (0.71) and relatively large δ (1480 GM), while DPH (D-π-A) with the substitutedamino group at its terminus possesses the largest δ (2800 GM) and the longest emission wavelength (620 nm). The idealest terminal substituent should not be the alkoxy group but the substitutedamino group. This class of dicyanostilbene dyes possess small molecule size, large δ (830-2800 GM), long-wavelength emission (459-620 nm) and large Stokes shift (80-206 nm), and are ideal chromophores for TPF labels and probes.

Two-photon fluorescent sodium ion probe and its synthetic method and application (by machine translation)

The invention belongs to the technical field of fine chemicals, in particular to a two-photon fluorescent sodium ion probe and its synthetic method and application, the probe in order to double-cyano stilbene is two-photon fluorescent matrix preparation. The probe molecules of small volume, to the sodium ion has very good selectivity, but zinc, potassium, calcium, magnesium, manganese, mercury and sodium ion other than the ion detection without interference, can detect micromolar concentration of the sodium ion. After the probe molecule complex sodium fluorescence intensity drop, sodium ion content can be two-photon fluorescence detection. Two-photon fluorescence microscopy imaging experiment shows the type of probe to the fibroblast like cells or tissue permeability, itself is not toxic to the cells, is especially suitable for the cell in the sodium ion concentration change and mercury ion distribution detection, in biological, in the medical field has great application value.
