Abstract

A large number of fluorescent sensors for cations that use a photoinduced electron transfer (PET) process to signal cation binding have been developed over the past three decades.1 The PET process of some of these sensors depends on having a tertiary nitrogen atom as a part of the receptor for cations. While these sensors work well as cation sensors, they also generate a fluorescent signal due to protonation of these receptors. The goal of this project is to design a fluorescent sensor that uses the same cation receptors but would not generate a signal for protons. Our new sensor has an additional PET pathway that is triggered when the tertiary nitrogen of the receptor is protonated.
