Length-dependent conductance of oligothiophenes.
J. Am. Chem. Soc. 136(29) , 10486-92, (2014) We have measured the single-molecule conductance of a family of oligothiophenes comprising 1-6 thiophene moieties terminated with methyl-sulfide linkers using the scanning tunneling microscope-based break-junction technique. We find an anomalous behavior: the... |

Synthesis and evaluation of new spacers for use as dsDNA end-caps.
Bioconjug. Chem. 21(8) , 1545-53, (2010) A series of aliphatic and aromatic spacer molecules designed to cap the ends of DNA duplexes have been synthesized. The spacers were converted into dimethoxytrityl-protected phosphoramidites as synthons for oligonucleotides synthesis. The effect of the spacer... |

Spectroscopy and single-molecule emission of a fluorene-terthiophene oligomer.
J. Phys. Chem. B 115(42) , 12028-35, (2011) We study the thiophene-based oligomer poly[2,7-(9,9-bis(2'-ethylhexyl)fluorene)-alt-2,5-terthiophene] (PF3T) in solution and when dispersed at low concentration into a polynorbornene matrix. We find that at high concentration in solution the 0-0 electronic tr... |

Chemical fingerprint of commercial Radix Echinopsis and quantitative analysis of alpha-terthienyl.
J. Sep. Sci. 33(4-5) , 530-8, (2010) New TLC, HPLC and LC/MS methods were developed for the rapid separation, characterization and quantitation of thiophenes in Radix Echinopsis, a herbal medicine, which has been used in China for long history. Nineteen commercial batches of this herb were analy... |

Triplet excited state characters and photosensitization mechanisms of α-terthienyl: A theoretical study
J. Photochem. Photobiol. B, Biol. 94(1) , 51-3, (2009) The triplet excited (T 1) state characters of α-terthienyl (α-T) have been investigated using density functional theory calculations, based on which, its photosensitization mechanisms were explored. Primarily, the direct oxidation to the DNA bases by the T 1 ... |
