Cryo Electron Tomography Reveals Confined Complex Morphologies of Tripeptide‐Containing Amphiphilic Double‐Comb Diblock Copolymers

“…Comblike polymers exist with hydrophobic [16] as well as hydrophilic side chains [17] and also as random copolymers with both types of side chains [18} . Comb-like polymers have been coupled to other linear [19} or dendritic [20} segments forming AB [19,20] as well as ABA [21] type bloc copolymers. Gnanou et al described a ROMP strategy towards amphiphilic block copolymers using norbornene-based macromonomers with polystyrene and poly(ethylene oxide) side chains, respectively.…”

Synthesis and Self‐Assembly of Brush‐Rod Diblock Copolymers in the Mixed Solvent of THF/H2O

“…Figure 2 depicts the 1 H NMR spectra of the macroinitiator and the copolymer PEGMA 37 -b-MBPS 87 , respectively. The assignments of resonance peaks is shown in the Figure. [18, [24][25][26] The M n of macroinitiator was determined according to the area ratio of methoxy to aromatic group, [22] while the DP n of PMBPS block was determined based on the area ratio of alkoxy protons of both blocks to aromatic protons of PMBPS blocks. [20] The characterization results of GPC and 1 H NMR are summarized in Table 1.…”

The Patterning and Alignment of Muscle Cells Using the Selective Adhesion of Poly(oligoethylene glycol methyl ether methacrylate)‐based ABA Block Copolymers

“…Materials: Poly(oligoethylene glycol methyl ether methacrylate)-block-poly(methylphenylsilane)-block-poly(oligoethylene glycol methyl ether methacrylate) (POEGMA-PMPS-POEGMA) 1 was synthesized according to procedures previously described [28] and poly(oligoethylene glycol methyl ether methacrylate)-block-polystyrene-block-poly(oligoethylene glycol methyl ether methacrylate) (POEGMA-PS-POEGMA) 2 was synthesized according to a procedure previously described in a preliminary form [11]; a more detailed synthetic discussion is forthcoming. Ultrapure water (18 MX cm) was generated using a Barnstead EASYpure LF water purification system.…”
