The polycarboxylates are terephthalic acid (H2BDC), 1,3,5-benzenetricarboxylic acid (H3BTB), and 1,2,4,5-tetrakis(4-carboxyphenyl)benzene (H4TCPB). Structural description of CPs reveals the flexibility of the carborane ligands and their ability to construct extended structures. The CP containing Co(II), BTB, and L2 behaves as a crystalline sponge for a variety of guests, showing a higher affinity for aromatic guest molecules. Single-crystal nanoindentation experiments indicate that a high number of specific interactions between the guests and the CP framework result in a high elastic modulus and hardness values. | Versión del editor: | http://dx.doi.org/10.1021/acs.cgd.6b01682 | URI: | http://hdl.handle.net/10261/143526 | DOI: | 10.1021/acs.cgd.6b01682 | ISSN: | 1528-7483 |
