Abstract
- Two new 3D framework materials containing Bi2O2 layers and Bi4O3 chains have been obtained hydrothermally via the reactions between bismuth nitrate with terephthalic acid (TA) and bismuth nitrate with nitro-terephthalic acid (NO2TA), respectively. The Bi2O2 layers are connected into a 3D structure via bridging TA ligands to form Bi2O2(TA) (1), while the novel Bi4O3 chains are connected into a 3D framework via linking NO2TA ligands to form Bi4O3(NO2TA)3(H2O)·(H2O)0.68 (2). Compound 1 exhibits photoluminescence that is red-shifted compared to that of the TA ligand, while the photoluminescence is quenched in both compound 2 and the NO2TA ligand.
