Specifications | MSDS | Literature and Reviews


[p-Terphenyl]-4,4''-dicarboxylic acid (H2TPDC) is a linear terphenyl with one carboxylic acid group on each end of the structure at 4,4'-positions.

Thermal annealing treatment for the reticular dysprosium (Dy) with rigid molecular ligand linker [p-terphenyl]-4,4''-dicarboxylic acid (Dy:H2TPDC) architecture gives rise to an unprecedented quasi-hexagonal nanostructure. The structure is based on dinuclear dysprosium clusters, exhibiting a unique six-fold Dy⋯O bonding motif.
