A Single-Dye System for Wool-Polyester Blends
Research Journal of Textile and Apparel, 2000Co-Authors: Y.c. Chao, S.m. LinAbstract:The synthesis of a series of disperse dyes containing a Carboxy Group is described. The dyes were applied to polyester, wool and wool-polyester blend fabrics and their dyeing and fastness properties evaluated. The levelling and fastness properties of all dyed samples meet commercial requirements. The effects of the Carboxy Group on the colour, dyeing and fastness properties ofthe dyes are discussed.

Carboxy Group derivatization for enhanced electron-transfer dissociation mass spectrometric analysis of phosphopeptides.
Proteomics, 2009Co-Authors: Lijuan Zhang, Pengyuan YangAbstract:A novel strategy based on Carboxy Group derivatization is presented for specific characterization of phosphopeptides. By tagging the Carboxy Group with 1-(2-pyrimidyl) piperazine (PP), the ion charge states of phosphopeptides can be largely enhanced, showing great advantages for sequencing phosphorylated peptides with electron-transfer dissociation MS. Besides, after PP-derivatization, most non-specific bindings can be avoided by eliminating the interaction between the Carboxy Group and TiO 2 , greatly improving the specificity of TiO 2 -based phosphopeptide enrichment strategy. Moreover, being tagged with a hydrophobic Group, the retention time of phosphopeptides in RPLC can be prolonged, overcoming the difficulty of separating phosphopeptides in RPLC-based approach. Together with several other advantages, such as ease of handling, rapid reaction time, broad applicability and good reproducibility, this PP-derivatization method is promising for high-throughput phospho-proteome research.

Mass spectrometry analysis of phosphopeptides after peptide Carboxy Group derivatization.
Analytical chemistry, 2008Co-Authors: Lijuan Zhang, Pengyuan YangAbstract:A nearly 100% yield peptide Carboxy Group derivatization method was offered to largely enhance phosphopeptide ionization efficiency. This method, adopting 1-(2-pyrimidyl) piperazine (PP) as the derivatization reagent, shows several advantages such as good reproducibility, ease of handling, rapid reaction time, and no side reaction. PP derivatization improves the hydrophobicities, pI values, and gas-phase basicities of peptides especially those of phosphopeptides. In the matrix assisted laser desorption ionization (MALDI) source, the ionization efficiencies of four synthetic phosphopeptides were increased by 50−101 times while that of three nonphosphopeptides were 10−40-fold. In the electrospray ionization (ESI) source, PP-derivatized phosphopeptides also gave much higher ionization efficiency improvements than nonphosphopeptides. When this method was applied to much more complex mixtures, tryptic BSA digests spiked with one single phosphopeptide in different molar ratios, the signal intensity of this phos...

Correction: A gold isocyanide complex with a pendant Carboxy Group: orthogonal molecular arrangements and hypsochromically shifted luminescent mechanochromism.
Chemical communications (Cambridge England), 2018Co-Authors: Tomohiro Seki, Koh Kobayashi, Takaki Mashimo, Hajime ItoAbstract:Correction for 'A gold isocyanide complex with a pendant Carboxy Group: orthogonal molecular arrangements and hypsochromically shifted luminescent mechanochromism' by Tomohiro Seki et al., Chem.

a gold isocyanide complex with a pendant Carboxy Group orthogonal molecular arrangements and hypsochromically shifted luminescent mechanochromism
Chemical Communications, 2018Co-Authors: Tomohiro Seki, Koh Kobayashi, Takaki MashimoAbstract:The epistatic double hydrogen bonds that arise from the presence of a pendant Carboxy Group in a gold isocyanide complex result in strong aurophilic interactions in a magenta-emitting polymorph. This is due to the lack of the typically antiparallel dimer arrangements, which often prevent the formation of strong aurophilic interactions. Furthermore, this polymorph shows hypsochromically shifted luminescence mechanochromism.
