ROP of bulky functional β-lactones mediated by an achiral diamino-bis(phenolate) yttrium catalyst affords syndio-enriched polyhydroxyalkanoates.
Non-covalent interactions (NCIs) can guide stereoselective ring-opening polymerization (ROP) of racemic β-lactones mediated by achiral complexes, towards stereoregular polyhydroxyalkanoates (PHAs).
The incorporation of polymer dots (2–7 nm) into the blue phase liquid crystal (BPLC) matrix results in a significant extension of the BP stability range, attributed to defect core replacement and an adaptive defect core targeting mechanism.
QDs at ≤1 wt% are confined within defect core, mimic BP lattice, and exhibit strong diffraction peaks in Synchrotron USAXS profiles. At ≥3 wt%, QDs aggregate and do not confine within defect core, with X-ray profile indicating colloidal formation.
The ROCOP of equimolar mixtures of (R)-CLnBu/(S)-CLMe enabled the assessment of the ROP stereocontrol ability of yttrium catalysts through the degree of alternation via detailed mass spectrometric analyses.
