Title: Flexible porous organic polymers with 1,2-diol subunits favoring the high loading of Pd nanoparticles,

Nanoscale, 2025, 17, 9914-9919.

Abstract:

In recent years, the flexibility of porous organic polymers has demonstrated very unique properties during their applications.

This

paper reports a novel soluble porous polymer (named BIT-POP-75 and

BIT-POP-75-OH) with 1,2-diketone and 1,2-diol subunits in the flexible

polymer chain using contorted subunits. The solubility of the porous

polymer and the flexible chelating 1,2-diol moiety facilitates the high

loading and uniform dispersion of Pd nanoparticles to give the catalyst

Pd@BIT-POP-75-OH, which shows high efficiency (kapp = 0.965 min?1) for

the catalytic reduction of 4-nitrophenol with good recyclability (10

cycles).
