Abstract

Rhythm is a dansyl: A novel dansyl-pyrene conjugate functions as a fluorescence signaling unit showing strong fluorescence quenching upon interaction with copper(II) metal ions. On the other hand, the two-photon absorption (TPA) cross-section increased from 374 to 3022 GM (at 770 nm) upon interaction with copper(II) ions, thus allowing their selective detection in aqueous solutions.
