Carbon dots and their derivatives with fascinating photoluminescent properties have recently attracted tremendous scientific attention. This work describes the preparation of novel fluorescent bentonite clay (B), modified carbon dots...
The possible origin of luminescent properties of biodegradable photoluminescent polyesters (BPLPs) has been revealed by isolation and identification of luminescent agent from the hydrolyzate of BPLP. Elemental analysis, ESI-MS, (1)H, (13)C, 2D HSQC and COSY NMR spectra confirmed the chemical structure as 5-oxo-2,3-dihydro-5H-[1,3]thiazolo[3,2-a]pyridine-3,7-dicarboxylic acid (TPA).
A method of introducing intrinsically photo luminescent properties to biodegradable polymer is introduced, exemplified by the synthesis of intrinsically photoluminescent polylactones that enable non-invasive monitoring and tracking of material degradation in vivo in realtime, as well as the formation of theranostic nanoparticles for cancer imaging and drug delivery.
The synthesis of photoluminescent conjugated polymer silica ionogels using sol-gel chemistry is described. Cooperative self-assembly of an ionic liquid, the silica precursor and poly(9,9-dioctylfluorene) (PFO) via hydrogen bonding and π-stacking interactions drives formation of the PFO β-phase.
