One novel near-infrared ytterbium metal–organic framework based on an unprecedented [Yb6(μ2-OH)2(μ3-OH)6]10 + cluster

Breathing 3D Frameworks with T-Shaped Connecting Ligand Exhibiting Solvent Induction, Metal Ions Effect and Luminescent Properties

“…The multidentate ligand 2,2 -bipyridine-5,5 -dicarboxylic acid (H 2 bpdc) is a good candidate because it contains two types of coordination groups-carboxylate groups and chelating position N-donors-which can act in linear bridging mode and/or T-shaped connecting mode [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37]. To date, there are 20 different coordination modes for H 2 bpdc ligand observed in the structures retrieved from the Cambridge Structural Database (CSD version 5.38, February 2017) [38] (Figure 1, Scheme S1).…”
