Construction of aromatic-ring-layered structures using a terphenylene-layered polymer as the scaffold

Abstract

A series of aromatic-ring-layered polymers were synthesized by the polymer reaction using a terphenylene-layered polymer as a scaffold. FT-IR spectra of the resulting polymers revealed that aromatic rings were quantitatively introduced into the terphenylene-layered polymer backbone. UV-vis absorption spectra exhibited intramolecular interactions among the layered aromatic rings within a single polymer chain. Excimer emission from the layered aromatic units was observed in the fluorescence spectra of the polymers, even in dilute solution, suggesting intramolecular interactions among the aromatic units in the excited state. This polymer reaction method was shown to be a convenient method to align various aromatic rings one-dimensionally in a single polymer chain.
