Concurrent genesis of color and electrical conductivity in leathers through in‐situ polymerization of aniline for smart product applications

28-Feb-2015 | Wegene Jima Demisie, Thanikaivelan Palanisamy, Krishnaraj Kaliappa, Phebe Kavati, Chandrasekaran Bangaru, Polymers for Advanced Technologies, 2015

We present a simple method to produce self‐colored and conducting leathers using in‐situ polymerization of aniline with ammonium persulfate as oxidant and hydrochloric acid as dopant. The structural and morphological features of treated leathers were examined using Fourier transformed infra‐red ...

Panchromatic Luminescence from Julolidine Dyes Exhibiting Excited State Intramolecular Proton Transfer

28-Feb-2015 | Andrea Barbieri; Raymond Ziessel; Barbara - Ventura; Nicola Armaroli; Maria Pia Gullo; Adela Nano, Chemical Communication, 2015

The preparation and the photophysical behavior of novel julolidine derivatives designed for displaying excited state intramolecular proton transfer (ESIPT) are reported. These dyes exhibit panchromatic photoluminescence covering the whole visible spectral range, both in organic solvents and in ...

Structural heterogeneity and dynamics of dyes on TiO2: implications for charge transfer across organic–inorganic interfaces

28-Feb-2015 | Jeffrey R. Christianson; J. R. Schmidt, Physical Chemistry Chemical Physics, 2015

Charge transfer across organic–inorganic interfaces plays a vital role in many important applications. Dye–semiconductor systems are the prototypical such interface and provide an excellent platform for exploring the underlying molecular-level factors that affect charge transfer dynamics and ...

Synthesis of polymeric dyes based on waterborne polyurethane for improved color stability

25-Feb-2015 | Haiyan Mao; Chaoxia Wang; Youjiang Wang, New Journal of Chemistry, 2015

Waterborne polyurethane covalently bonded anthraquinone dye chromophore was successfully synthesized via incorporating micromolecule Disperse Red 91 into the polyurethane skeleton. The number- and weight-average molecular weights of the waterborne polyurethane based polymeric dye were about 6.57 ...

Taking Up the Cyanine Challenge with Quantum Tools

24-Feb-2015 | Boris Le Guennic; Denis Jacquemin, Accounts of Chemical Research, 2015

ConspectusCyanine derivatives, named from the Greek word kyanos meaning dark-blue, were discovered more than 150 years ago and remain one of the most widely used classes of organic dyes with contemporary applications in photography (panchromatic emulsions), information storage (CD-R and DVD-R ...

Modulating Fluorescence Anisotropy of Terminally Labeled Double-Stranded DNA via the Interaction between Dye and Nucleotides for Rational Design of DNA Recognition Based Applications

23-Feb-2015 | Hongduan Huang; Hejia Wei; Mingjian Zou; Xiao Xu; Bin Xia; Feng Liu; Na Li, Analytical Chemistry, 2015

Effective signal enhancement for fluorescence anisotropy in a simple manner is most desirable for fluorescence anisotropy method development. This work aimed to provide insights into the fluorescence anisotropy of terminally labeled double-stranded DNA (dsDNA) to facilitate a facile and universal ...
