Broadening through-space conjugation in polyphosphates through α-aminophosphonate bridges for a noteworthy red shift in luminescence

Abstract

Incorporating α-aminophosphonate bridges into polyphosphonate chains effectively broadens the through-space conjugation (TSC), enhancing spatial electron delocalization. This results in a notable emission redshift to 630 nm with remarkable efficiency, demonstrating a robust structure–property relationship in the unconventional fluorescent polymers.
