Cover Picture: Synthesis, Characterization and Properties of Novel Star-Shaped π-Conjugated Oligomers with Triphenylamine Core (Chin. J. Chem. 4/2013)
The cover picture shows four novel star-shaped π-conjugated oligomers. The core of these new star-shaped oligomers is electron-donating group, triphenylamine. The peripheral units are four hole-transporting chromophores with different electron-donating ability. The photophysical properties of these oligomers can be tuned through changing the electron-donating ability and conjugation length of the peripheral units. The fluorescence quenching properties indicate that efficient charge transfer can happen between the star-shaped oligomers and EP-PDI. More details are discussed in the article by Tian et al. on page 456–464.
