2,2’-diamino-[1,1’-biphenyl]-4,4’dicarboxylic acid); DMF =
N,N-dimethylformamide] are presented here. These MOFs display structural
variety with diverse topologies and new structural features.
Luminescence studies revealed that both MOFs display ligand based
fluorescence with small differences in emission profiles possibly
attributable to the difference in charge density of the metal ions
combined with the different conformation adopted by the ligand in the
crystal structures of 1 and 2. Furthermore, initial sensing studies
reveal that both MOFs can potentially function as fluorescent sensors
for gas phase aldehydes. (C) 2018 Elsevier Ltd. All rights reserved."
