The MOF with the CCDC refcode QOTZEG was synthesized following a modified procedure from the literature. 69 0.594 g LaCl3*7H2O and 0.235 g BTC were dissolved in DMF. The mixture was heated to 150 °C for two days in a Teflon-lined autoclave. After the reaction mixture cooled to room temperature, a white powder was isolated by centrifuge. The powder was washed three times with DMF then three times with methanol for several hours each time. The powder was dried under vacuum at 100 °C overnight, resulting in ~400 mg of MOF powder.
