This paper focuses on an ultrathin polymer optode containing europium complexes (p(DDA-Eu(TTA)3Phen)). Ultrathin films were prepared by the Langmuir–Blodgett (LB) technique; a mixed solution of poly(N-dodecylacrylamide) (pDDA) and tris(4,4,4-trifluoro-1-(2-thienyl)-1,3-butanediono)-1,10-phenanthroline europium(III) (Eu(TTA)3Phen) was spread onto a water subphase and the condensed monolayer was transferred onto a solid substrate. The spectroscopic properties and layer structure of p(DDA-Eu(TTA)3P
This paper describes the fabrication of hybrid nanoassemblies with polymer brushes and gold nanoparticles enabling detection of nanoscale optical changes based on localized surface plasmon resonance. The reversible and thermosensitive nanoscale actuation is achieved by combining stimuli-responsive polymer brushes and gold nanoparticles independently and selectively assembled on substrates. These hybrid nanoassemblies are assembled on numerous substrates and will be applicable for optoelectronics
This Article describes a unique approach to building silsesquioxane nanoassemblies based on the Langmuir−Blodgett (LB) technique. Poly(N-dodecylacrylamide-co-3-methacryloxypropyl-T8-heptatrifluoropropyl (or heptaphenylpropyl) POSS)s (p(DDA/SQ)s) were synthesized through free radical copolymerization using propyl methacrylate-substituted polyhedral oligomeric silsesquioxane (POSS) monomers containing seven nonreactive trifluoropropyl or phenyl groups (R7(Si8O12)(CH2CH2CH2OCOCH3C═CH2) (where R is
Fabrication of smooth and flexible free-standing films with universal thickness and a highly ordered layer structure is described in this paper. N-Dodecylacrylamide polymer forms a well-defined monolayer on a water surface. The acrylamide polymer chains are strongly associated by hydrogen bonding of amide groups in the monolayer, thereby forming a two-dimensional network (polymer nanosheet). The monolayer is transferable onto a substrate using the Langmuir–Blodgett (LB) method with regular depos
Fluorinated cellulose nanofiber assemblies exhibit high oil–water separation efficiency and recyclability (at least 50 times) for practical applications.
This paper focuses on waveguide technique versatility for direct observation of photochemical reactions in polymer ultrathin films. Monolayers from the copolymer of 9-anthrylmethyl methacrylate (AMMA) with neopentyl methacrylamide (nPMA) were deposited on a tapered quartz waveguide by the Langmuir−Blodgett (LB) technique, and spectroscopic properties of the copolymer (p(nPMA-AMMA)) monolayer were precisely monitored by an integrated optical waveguide technique. Magnitude of absorbance increased

We have developed so-called polymer Langmuir–Blodgett (LB) films (polymer nanosheets) based on acrylamide polymer and its copolymers, and have reported a series of various functional polymer nanosheet assemblies. To fabricate photofunctional nanodevices, we have succeeded in the introduction of various photoactive chromophores such as redox species, aromatic hydrocarbons, optically nonlinear groups, and metal nanoparticles into polymer nanosheet assemblies. In this article, we focus on our recen
