As a result of the gas chromatography–mass spectrometry (GC-MS) analysis, mass ions of 587.91, 575.46, and 577.48 Da with retention times of 27.994, 33.311, and 33.121 min, respectively (Supplementary Figure S2), were present in the carotenoid extract from ANT_H53B. This result confirmed ...
Mixed ligands MOFs can be constructed from metal ions and carboxylic acid and nitrogen-containing ligands [4], [5]. In most situations, N-containing ligands are electrically neutral, while carboxylate ligands are negatively charged. Among organic aromatic multicarboxylates like the 3′,5′-di...
