a Molecular weights and dispersity control for the obtained PBLG at different polymerization conditions mediated by UiO-66-2. For all mBLG-NCA/mUiO-66 ratios, a fixed [BLG-NCA]0 (0.114 M) in a fixed volume of anhydrous DCM was used. b GPC-dRI curves of the PBLGs are shown in panel a, with matching colors denoting the same dataset. c SEM visualization of UiO-66 NPs recovered after being used as a catalyst for NCA-ROP. d GPC-dRI curves, molecular weights, and dispersity information of PBLGs obtained using pristine and recycled MOF co-catalyst.
