Synthesis and characterization of poly(decyloxy-p-phenylenevinylene)

Synthesis of Light-Emitting Conjugated Polymers for Applications in Electroluminescent Devices

“…396 Cross metathesis of 2,5-dialkoxy-1,4-divinylbenzenes produces oligomeric 39e-g. [397][398][399] Cathodic electropolymerization of 2,5-bis(dibromomethyl)decyloxybenzene has been used to make the decyloxy-PPV 52. 400 Lahti and co-workers have used Heck coupling of a 4-vinylbromobenzene AB monomer to make regioregular (head-to-tail) poly(2-dodecyloxyphenylene vinylene) (53) (Scheme 10), which shows strong yellow PL and EL (λ max ) 542 and 540 nm, respectively). 401 So far there has been no comparative study on regiorandom vs regioregular dodecyloxy-PPV 53, but it is known that regioregularity in other conjugated polymers, e.g.…”

“…Low molecular mass polymers can be prepared by Stille coupling of dialkoxyaryl dihalides or ditriflates with bis-stannylethene. , The cyclophane-substituted PPV 51 prepared by Stille coupling shows yellow-green EL (λ max = 563 nm) .
