DOI: 10.1021/acs.orglett.4c04203

Abstract: We report the syntheses, spectroscopic analyses, and solid-state structural evidence of a quasi-planar aromatic [38] E-ethylene bridged octaphyrin (1.2.1.0.1.2.1.0) exhibiting NIR absorption. The chemical oxidation using an appropriate oxidant led to unique π reconstruction via… read more here.

Abstract: Near-infrared absorption metal complexes (NIRMCs) have been traditionally associated with the π-expanded macrocycle structure. However, macrocyclic ligands suitable for NIRMCs require a laborious synthetic route, and are a limited few. Herein, we report a kind… read more here.

DOI: 10.1039/d3cc00729d

Abstract: While the heteroannulation of arylene diimides serves as a powerful approach for designing new π-functional materials, most of the heteroannulated arylene diimides are constructed based on π-extension at their bay-areas or ortho-directions. Herein, based on… read more here.

DOI: 10.1039/d4dt02865a

Abstract: A BCA cis-coordinated MOF (1) was initially discovered to exhibit electron transfer photochromism. Remarkably, the photogenerated radicals (1P) showed a maximum absorption enhancement peak at 1158 nm, resulting from the synergistic effects of planar π-conjugation… read more here.
