摘要
Meticulous regulation of pore chemistry is essential for elucidating the intricate mechanism of the adsorption efficacy of porous materials. However, it is a great challenge to address the functionalization of pore chemistry while preserving pore size and geometry. In this study, the robust NPU-1 series network is selected as a platform to address this challenge. By regulating the nitrogen distribution in bilayer-pyridine ligands, a series of coordination networks (NPU-1-TPB/TPP/TPT) with the same pore size and geometry but different pore polarity is obtained, affording an increase in C2H2 enthalpies from −28.3 to −33.1 kJ mol−1. In situ, infrared spectroscopy uncovers the enhanced C2H2 interaction with the central phenyl ring of bilayer-pyridine ligands with the extent of nitrogen functionalization.
