Unraveling the effect of topological structures of B/N‐doped conjugated macrocycles on spectral properties: A computational study

Smart Molecules, EarlyView.
Herein, we constructed a series of fully B‐doped, fully N‐doped and hybrid B/N‐doped conjugated macrocycles considering three key topological factors. At a fixed ring size, the spectra initially redshift then blueshift with varying B/N ratio, while ring size exhibits negligible impact on spectra.
