Arenedicarboximide Building Blocks for Fluorescent Photoinduced Electron Transfer pH Sensors Applicable with Different Media and Communication Wavelengths

Abstract

A whole family of modular photoinduced electron transfer (PET) sensors has been constructed from a single simple reaction type with commercially available materials. This family, one member of which is shown here, possesses amine receptors for protons and arenedicarboximide fluorophores addressable at different wavelengths. Its pH-sensing behaviour is examined in solution and in polymer membrane matrices, which are crucial for the use of fluorescent PET sensors as optode pH monitors.
