50th Anniversary Perspective: Functional Nanoparticles from the Solution Self-Assembly of Block Copolymers

“…102 Moreover, studies of PFDMS BCPs with short corona -forming blocks showed that these materials yielded platelet micelles. 103 A wide range of crystallizable core-forming blocks other than PFDMS have now been employed to enable the formation of cylindrical/fiber-like micelles with crystalline cores and these include poly(3-hexylthiophene)), [104][105][106][107][108][109] poly(L-lactic acid) (PLLA), [110][111][112][113] polycaprolactone (PCL), 114,115 PEO, 116 PE, [117][118][119][120] poly(acrylonitrile), 121 poly(ferrocenyldimethylgermane) (PFDMG), 122 poly(ferrocenyldiethylsilane) (PFDES), 123 poly(ferrocenylmethylsilane)(PFMS), 124 PCL/PLLA, 125 poly(perfluoroethyloctylmethacrylate), 126,127 cholestorol-based polymers, 128 polyacetylene, 129,130 poly(pphenylene), 131 poly(3-heptylselenophene), 132 polyfluorene, [133][134][135] poly(pphenyleneethynylene), 136,137 poly(p-phenylenevinylene), [138][139][140][141][142] cyclic polypeptoids, 143 and poly(2-isopropyl-2-oxazoline).…”

Emerging applications for living crystallization-driven self-assembly

“…Over the past two decades, studies of the CDSA of BCPs with a crystallizable core-forming block in selective solvents have expanded dramatically. CDSA has been employed to fabricate mainly cylindrical and/or platelet micelles based on crystalline (or in some cases liquid crystalline) cores of PFDMS, 31,[34][35][36] poly(ferrocenylmethylsilane) (PFMS), 37 poly(ferrocenyldiethylsilane) (PFDES), 38 poly(ferrocenyldimethylgermane) (PFDMG), 39 other polymetallocenes, 40,41 poly(L-lactic acid) (PLLA), [42][43][44][45][46][47][48] polycaprolactone (PCL), 49,50,59,60,[51][52][53][54][55][56][57][58] PCL/PLLA copolymers, 61 polycarbonate, 62 poly(ethylene oxide/glycol) (PEO/PEG), [63][64][65] poly(pdioxanone) (PPDO), [66][67][68] polyethylene (PE), 69,70,[79][80][81][82][83][71][72][73][74]…”

Synthesis of PS-b-PPOA-b-PS triblock copolymer via sequential free radical polymerization and ATRP

“…Generally, block copolymers can be synthesized via two common strategies of sequential feeding and site transformation. The sequential feeding method means that block copolymer can be obtained by the sequential feeding of different monomers under the same kind of living polymerization mechanism such as anionic, cationic, group transfer, and living radical polymerization . The site transformation approach refers to synthesizing the block copolymers via different polymerization mechanisms, for which bi‐ and multifunctional initiators have been designed and prepared for attaining different polymerization mechanism demands of the monomers with different chemical structures .…”
