Description	Rozpustné poly(difenylacetylen)y (PDA) zakončené PhCO-(PDA-C) nebo Ph2C= (PDA-P) skupinami byly připraveny McMurry reduktivním kuplováním benzilu a karbonyl-olefinu výměnnou reakcí tetrafenyl ethenu a benzilu. Fluorene-9-ylidenové skupiny byly zavedeny do PDA McMurryho spojováním PDA-C s fluoren-9-one a kopolymerizací benzilu a fluoren-9-one. Připravené oligomery jsou na vzduchu stálé a rozpustné v řadě rozpouštědel. Mohou být nanášeny na podložky z roztoku, přičemž tvoří tenké filmy vhodné pro měření elektrických a optoelektrických vlastností. (cs) Soluble poly(diphenylacetylene)s (PDA) capped with PhCO- groups (PDA-C) and Ph2C= groups (PDA-P) were prepared via McMurry reductive coupling of benzil and carbonyl-olefin exchange reaction of tetraphenylethene and benzil, respectively. Fluoren-9-ylidene groups have been introduced into PDA by the McMurry coupling of PDA-C with fluoren-9-one and via copolymerization of benzil and fluoren-9-one. The oligomers prepared are stable in air, soluble in a variety of solvents. They can be processed by casting, to form good-quality thin films suitable for measurements of electrical and optoelectrical properties.
