【J. Mater. Chem. C】Evidence of concerted inversion for the photon-induced molecular switching of azobenzene using rotation-free azobenzene derivatives
The excited state relaxation of two types of azobenzene derivative excited at 350 nm in the short-wavelength (S2([small pi], [small pi]*)) band was studied by transient absorption spectroscopy. We compared the relaxation dynamics and the time-resolved anisotropic relaxation properties of these two molecules in liquid solution and in bulk film. The average relaxation life-time for Azo-2 in bulk fil...

【ACS Appl. Mater. Interfaces】Fluorescent pH Sensor Based on Ag@SiO2 Core–Shell Nanoparticle
We have demonstrated a novel method for the preparation of a fluorescence-based pH sensor by combining the plasmon resonance band of Ag core and pH sensitive dye (HPTS). A thickness-variable silica shell is placed between Ag core and HPTS dye to achieve the maximum fluorescence enhancement. At the shell thickness of 8 nm, the fluorescence intensity increases 4 and ...

【ACS Appl Mater Interfaces】Facile Fabrication of Lubricant-Infused Wrinkling Surface for Preventing Thrombus Formation and Infection
Despite the advanced modern biotechniques, thrombosis and bacterial infection of biomedical devices remain common complications that are associated with morbidity and mortality. Most antifouling surfaces are in solid form and cannot simultaneously fulfill the requirements for antithrombosis and antibacterial efficacy. In this work, we present a facile strategy to fabricate a slippery surface. This...

【Mater Lett】Preparation of functionalized graphene/SEBS-g-MAH nanocomposites and improvement of its electrical, mechanical properties
Graphene was first surface modified with octadecylamine to prevent the aggregation of graphene itself and also improve the compatibility between the graphene and polymer matrix. Then it was solution mixed with SEBS grafted with maleic anhydride (SEBS-g-MAH) to prepare graphene/SEBS-g-MAH nanocomposites. FTIR results show that esterification reaction took place by a “grafting to” method between m...

ACS Appl. Mater. Interfaces, 2015, 7(32), 17545-17551. Ultrafast Spreading Effect Induced Rapid Cells Trapping into Porous Scaffold with Superhydrophilic Surface,
In this contribution,
superhydrophilic chitosan-based scaffolds with ultrafast spreading property were
fabricated and used to improve the trapped efficiency of cells. The ultrafast
spreading property allowed cells to be trapped into the internal 3D porous
structures of the prepared scaffolds more quickly and effectively. Cell
adhesion, growth, and proliferation were also improved,...

Biomed. Mater. 2013, 8 045008. Bioinspired methodology for preparing magnetic responsive chitosan beads to be integrated in a tubular bioreactor for biomedical applications
Magnetic responsive chitosan beads were prepared using a methodology inspired by the rolling of water droplets over lotus leaves. Liquid precursors containing chitosan and magnetic microparticles were dispensed in the form of spherical droplets and crosslinked with genipin over synthetic superhydrophobic surfaces. Scanning electronic microscopy, histology and micro-computed tomography were employe...

This
manuscript describes a series of mesogen-jacketed liquid crystalline polymers
(MJLCPs) and elastomers (MJLCEs) bearing a novel polynorbornene backbone, onto
which the liquid crystalline mesogen is laterally attached by a single covalent
bond without spacers.

[2012][Chem. Mater., 2012, 24 (12): 2364–2372]Family of Diazapentalene Chromophores and Narrow-Band-Gap Polymers: Synthesis, Halochromism, Halofluorism, and Visible–Near Infrared Photodetectivity
A family of pyrrolo[3,4-c]pyrrol-1(2H)-one (PPO) and 2,5-diazapentalene (DAP) chromophores and DAP-containing polymers were synthesized, and their optical and electrochemical properties were studied. PPO and DAP chromophores are readily obtained by chemical transformation of the lactam unit in diketopyrrolopyrrole (DPP) dyes and can be used as versatile building blocks for construction of a vari...
