摘要

In this work, we detail the synthesis and photophysical properties of a series of soluble polybipyridine ligands comprising one to five bipyridine units sandwiched between rigid carbon-carbon triple bonds substituted by 3, 4-dibutylthiophene repeating units. The dual Sonogashira coupling reaction of 5, 5'-dibromo-2, 2'-bipyridine with TMS-and (CH3) 2C (OH)- protected acetylene allows the synthesis of a dissymmetrically functionalized building ...
