文摘
- •
We report Ag+ two-photon fluorescence probes containing spirobifluorene for the first time.
- •
The molecules exhibit high selectivity and excellent sensitivity in both UV/Vis absorbance and one-photon fluorescence detection of Ag+.
- •
The molecules have large two-photon cross-sections.
- •
One molecule is a promising two-photon probe potentially applicable for bioimaging.
- •
Another molecule is an excellent probe to measure water content of organic solvents.
