Two Aromatic Rings Coupled a Sulfur-Containing Group to Favor Protein Electron Transfer by Instantaneous Formations of π∴S:π?π:S∴π or π∴π:S?π:π∴S Five-Electron Bindings
The cooperative interactions among two aromatic rings with a S-containing group are described, which may participate in electron hole transport in proteins. Ab initio calculations reveal the possibility for the formations of the π∴S:π?π:S∴π and π∴π:S?π:π∴S five-electron bindings in the corresponding microsurrounding structures in proteins, both facilitating electron hole transport as e...

[2015][J. Phys. Chem. C, 2015, 119 (45), 25243–25251]End-Group Engineering of Low-Bandgap Compounds for High-Detectivity Solution-Processed Small-Molecule Photodetectors
Several π-conjugated compounds based on diketopyrrolopyrrole and trithiophene substituted with different end groups (alkyl, alkyloxy, and alkylthio) were designed and synthesized for investigation of the material properties and photodetector performance brought by subtle changes in the end groups. Among all, compound 4 with hexylthio groups exhibits the most red-shifted absorption, strongest mo...

Intramolecular charge-transfer emission from conjugated polymer nanoparticles: the terminal group effect on electronic and optical properties
Tuning fluorescence properties and frontier orbital energy levels of hyperbranched conjugated polymer nanoparticles (HCPN-NMe) by the facile introduction of terminal N,N-dimethylaniline groups via an intramolecular charge transfer (ICT) process between the nanoparticle core and the terminal groups was demonstrated for the first time. Compared with the similar hyperbranched conjugated pol...

Water-Soluble Polymers Bearing Phosphorylcholine Group and Other Zwitterionic Groups for Carrying DNA Derivatives
Water-soluble polymers with equal positive and negative charges in the same monomer unit, such as the phosphorylcholine group and other zwitterionic groups, exhibit promising potential in gene delivery with appreciable transfection efficiency, compared with the traditional poly(ethylene glycol)-based polycation–gene complexes. These zwitterionic polymers with various archite...

Effect of Iron acetylacetonate on the crosslink structure, thermal and flammability properties of novel aromatic diamine-based benzoxazines containing cyano group
Iron acetylacetonate (Fe(AcAc)3) was chosen as catalyst for a novel aromatic diamine-based benzoxazine containing cyano group (BAPBACP). Its effect on the curing process, thermal and flammability properties of BAPBACP were investigated. The results indicated that without Fe(AcAc)3 the ring-opening polymerization of the BAPBACP monomer occurred and an arylamine Mannich bridge structure was formed a...

Preparation of Polymer Microspheres with Reactive Epoxy Group and Amino Groups as Stabilizers for Gold Nanocolloids with Recoverable Catalysis
Narrow disperse poly(divinylbenzene-co-glycidyl
methacrylate) (P(DVB-co-GMA))
microspheres with reactive epoxy group were prepared by distillation
precipitation copolymerization of divinylbenzene (DVB) and glycidyl
methacrylate (GMA) with benzoyl peroxide (BPO) as initiator in neat
acetonitrile. The epoxy group was modified with ethylenediaminie (EDA) for
transferring to amino group, which was use...

[JPS Part A] Poly(vinylphosphonate)s functionalized polymer microspheres via rare earth metal-mediated group transfer polymerization
We demonstrate a facile, yet efficient method for the
functionalization of crosslinked polystyrene (PS) microspheres
with biocompatible poly(vinylphosphonate)s via the combination
of a UV grafting polymerization and a surface-initiated group
transfer polymerization. Self-initiated photografting and photopolymerization
of ethylene glycol dimethacrylate results in direct
photografting of poly(ethyle...

Preparation of Monodisperse Crosslinked Polymer Microspheres Having Chloromethyl Group by Distillation-precipitation Polymerization
Monodisperse crosslinked poly(chloromethylstyrene-co-divinylbenzene) (poly(CMSt-co-DVB)) microspheres were prepared by distillation-precipitation copolymerization of chloromethylstyrene (CMSt) and divinylbenzene (DVB) in neat acetonitrile. The polymer particles had clean surfaces due to the absence of any added stabilizer. The size of the particles ranges from 2.59 μm to 3.19 μm and with mono-di...

Preparation of Narrow- or Monodisperse Polymer Microspheres with Active Hydroxyl Group by Distillation-precipitation Polymerization
Narrow-dispersion or monodisperse polymer microspheres with active hydroxyl groups were prepared by distillation–precipitation polymerization in the absence of any stabilizer. The monomer hydroxyethyl methacrylate (HEMA) was copolymerized with either commercial divinylbenzene (DVB) (containing 80 % of DVB isomers) or ethyleneglycol dimethacrylate (EGDMA) as crosslinker by distillation–precipitat...
