Abstract:

Using the diphenylamino group as the electron donor, the cyano group as the electron acceptor, and the dicyanostilbene as a two-photon fluorophore, a novel two-photon fluorescence solvatochromic probe(SP1) was developed by means of the structure-activity relationship of D-π-A(D: electron donor, A: electron acceptor) electron architecture. The structure was characterized and identified by means of nuclear magnetic resonance spectra and element analysis instrument. SP1 showed a wide range of 152 nm in solvent solvatochromism, the maximum emission wavelengths in cyclohexane and dimethylsulfoxide(DMSO) were 452 and 604 nm, respectively. It can be used for the detection of solvent polarity and viscosity. Solvents can also be identified according to maximum emission wavelengths. SP1 had a large two-photon absorption cross section, the maximum two-photon absorption cross-sections in cyclohexane and DMSO were 6670 and 2040 GM, respectively, and also had a large Stokes shift(194 nm). Its photostability, water solubility and cell permeability were excellent. The probe can be used for the measurement and imaging of cell viscosity.
