Precise one-pot synthesis of fully conjugated end-functionalized star polymers containing poly(fluorene-2,7-vinylene) (PFV) arms

A facile, precise one-pot synthesis of end-functionalized star (triarm) polymers consisting of poly(9,9-di- n -octylfluorene-2,7-vinylene)s (PFVs), the triblock copolymers [by incorporation of tri(2,5-dialkoxy-1,4-phenylene vinylene) or terthiophene units as the middle segment], has been achieved by...

Zusammenfassung:A facile, precise one-pot synthesis of end-functionalized star (triarm) polymers consisting of poly(9,9-di- n -octylfluorene-2,7-vinylene)s (PFVs), the triblock copolymers [by incorporation of tri(2,5-dialkoxy-1,4-phenylene vinylene) or terthiophene units as the middle segment], has been achieved by olefin metathesis followed by Wittig-type coupling; effects of the PFV conjugation length, the middle segment and the end groups on the emission properties have been studied.
