Specifications | MSDS | Literature and Reviews


4,4'-(Anthracene-9,10-diylbis(ethyne-2,1-diyl))dibenzoic acid, also referred to as H2ABEDB (CAS number 1562777-29-0), is an anthracene derivative with 4-benzoic acids joined linearly at 9,10-poisitons of the central ring of anthracene by two ethynyl groups.

Three-dimensional microporous NNU-27 using 4,4'-(anthracene-9,10-diylbis(ethyne-2,1-diyl))dibenzoic acid ligand shows new charge transport pathway of long-range π-conjugation of ligand in a zig-zag fashion with a high conductivity of 1.3 (±0.5) × 10-3 S/cm. NNU-28, a Zirconium- ABEDB MOF, is highly efficient for visible light driven CO2 reduction with a formate formation rate of 183.3 μmol h−1 mmol MOF−1. Anthracene-based ligand serves as an antenna for light harvesting and participates in CO2 reduction reaction by radical formation.

Zr–ABEDB MOF photocatalyst decorated by 1.0 wt% amount of Pt cocatalyst exhibited a hydrogen evolution rate as high as 704 μmol·h−1·g−1, ca. 220 times of that of pristine Zr–ABEDB MOF (3.2 μmol· h−1·g−1).
