The fabrication of two-photon absorption material is a versatile approach to achieve high resolution bioimaging with low phototoxicity yet remain sophisticated. Herein, a zwitterionic chromophore, MF, with D-π-A configuration has been rational designed and synthesized. Remarkably, MF exhibited enhanced one- and two-photon fluorescent in the aggregation states. Additionally, the obtained MFNPs encapsulated by Pluronic F-127, could be employed as a two-photon fluorescent probe for bioimaging. The results reveal that MFNPs could target mitochondria by using two-photon confocal microscopy and stimulated emission depletion nanoscopy methods.
