(Polymer Chemistry) Micro-dynamics mechanism of the phase transition behavior of poly(N-isopropylacrylamide-co-2-hydroxyethyl methacrylate) hydrogel revealed by two-dimensional correlation spectroscopy
In this study, the micro-dynamic mechanism of volume phase transition behavior of poly(N-isopropylacrylamide-co-2-hydroxyethyl methacrylate) (PNIPAM-co-HEMA) hydrogel was investigated by temperature-dependent FTIR spectroscopy in combination with the perturbation correlation moving window (PCMW2D) technique and generalized two-dimensional correlation analysis. In conventional 1D FTIR spectra ana...

Facile synthesis of photolabile dendritic-unit-bridged hyperbranched graft copolymers for stimuli-triggered topological transition and controlled release of Nile red
Different from hyperbranched star-like polymers
and dendritic brushes, dendritic-unit-bridged hyperbranched graft copolymers
(DHGCs) with branching point linked branches and linear grafts can be regarded
as a new subclass of hyperbranched-graft-linear copolymers. This study aims at the
synthesis and properties of photocleavable DHGCs comprising oligomeric branches
composed of poly(ethylene glyco...

Online Rheological Investigation on Ion-Induced Micelle Transition for Amphiphilic Polystyrene-block-Poly(acrylic acid) Diblock Copolymer in Dilute Solution
The ion-induced micellar transition is online-investigated by the
time dependence of the viscosity of the solution under shear flow for the first
time. During the morphological transition, the change in the micellar structure
can be tracked by the change in viscosity. Adding HCl or CaCl2 into preprepared
spherical micelle solution from the self-assembly of polystyrene-blockpoly(
acrylic acid) (PS1...

Modulated Nonlinear Optical Responses and Charge Transfer Transition in Endohedral Fullerene Dimers Na@C60C60@F with n-Fold Covalent Bond (n ) 1, 2, 5, and 6) and Long Range Ion Bond
Isomer structures of four endohedral fullerene dimers Na@C60C60@F with an n-fold bond (n ) 1, 2, 5 and
6) are obtained for the first time by using density functional theory. The n-fold bond depends on the dimeric
pattern between endohedral fullerenes Na@C60 and F@C60.

Large static first and second hyperpolarizabilities dominated by excess electron transition for radical ion pair salts M2+TCNQ(M = Li, Na, K)
The interesting radical ion pair salts M2+TCNQ (M = Li, Na, K) are a particular class of
charge transfer complexes with excess electron. The ground states of these complexes are triplet.
The C2v symmetry geometrical structures of the M2+TCNQ (M = Li, Na, K) with all-real
frequencies are obtained at the density functional theory (DFT) B3LYP/6-31+G(d) level. All
calculations of electric pr...

Cellulose-Based Dual Graft Molecular Brushes as Potential Drug Nanocarriers: Stimulus Responsive Micelles, Self-Assembled Phase Transition Behavior, and Tunable Crystalline Morphologies.
Well-defined cellulose-based dual graft molecular brushes, composed of ethyl cellulose-graft-poly(N,Ndimethylaminoethyl methacrylate)-graft-poly(ε-caprolactone) (EC-g-PDMAEMA-g-PCL), have been prepared by ring-opening polymerization (ROP) and atom transfer radical polymerization (ATRP). Unlike other brush copolymers, the new molecular brushes show some unique physicochemical properties and...

PEG-PCL 基温敏性嵌段-接枝共聚物胶束化与凝胶化
关键字：Block-graft copolymers，Micellization，Sol-to-gel transition
A series of triblock-graft copolymers PEG-b-[PCL-g-P(MEO2MA-co-OEGMA)]-b-PEG were synthesized by combination of ring-opening polymerization (ROP) and atomic transfer radical polymerization (ATRP). The phase transitions induced by temperature have been studied. The synthesized triblock-graft compolymer not only exhibited a hydrophilic, but also have temperature sensitivity. The triblock-graft c...
