Two hitherto unknown planar aromatic  fused heterocyclic macrocycles (184.108.40.206.1.0), with NIR absorption in free-base form and protonation-induced enhanced NIR emission, have been synthesized from easy to make precursors. The induced correspondence of fusion on the macrocyclic structure, electronic absorption, and emission spectra have been highlighted.
