Strong modulation of two-photon excited fluorescence of quadripolar dyes by (de)protonation.
Two quadripolar dyes have been designed and synthesized that present large cross sections for two-photon excitation and whose fluorescence responds strongly to (de)protonation. These dyes are considered as prototypes of molecular pH probes for multiphoton fluorescence microscopy.
