Alternating copolymers with glycyl-glycine and alanyl-alanine side-chain pendants: synthesis, characterization and solution properties

Recent advances in the development and applications of nonconventional luminescent polymers

“…Unusual luminescence characteristics in solution and in the solid state were observed, where only blue emission occurred in solution but in the solid-state tri-color emission (blue, green and red) was observed. 94 Yang et al observed that although succinimides act as common fluorescence quenchers of proteins, and common succinimide monomers are nonfluorescent but succinimidebased compounds and also succinimide-containing polymers became fluorescent only after functionalization with dithiol/ amino substituents without introducing any conjugated fluorescent entity. The unexpected fluorescence of dithio/aminosuccinimides originated from the spatial separation between the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO), realized from DFT calculations.…”

Cholate-conjugated cationic polymers for regulation of actin dynamics

“…41 Successful deprotection of the Boc groups was confirmed from the disappearance of the Boc-proton signal at about 1.42 ppm in the 1 H NMR spectra. 42 The 1 H NMR spectrum of deprotected side-chain Phe-containing polymer P(PEGMA- co -Phe-HEMA) ( CPF ) is shown in Fig. 1A (also see Fig.…”

Stimuli-Responsive Aggregation-Induced Emission (AIE)-Active Polymers for Biomedical Applications

“…De and co-workers synthesized amino acids , and dipeptide-derived polymaleimide-based alternating copolymers with stimuli-responsive characteristics for various applications. , These as-synthesized copolymers emitted bright-blue fluorescence in organic solvents and also exhibited stimuli-responsive fluorescence activity in water. Although in solution only blue emission was observed, in the solid phase three emissions (red, blue, and green) were monitored in the case of the synthesized polymers.…”

“…They attributed the emission to the clustering of locked carbonyls in maleic anhydride units. 120,121 De and co-workers synthesized amino acids 122,123 and dipeptide-derived 124 polymaleimide-based alternating copolymers with stimuli-responsive characteristics for various applications. 125,126 These as-synthesized copolymers emitted bright-blue fluorescence in organic solvents and also exhibited stimuli-responsive fluorescence activity in water.…”
