Abstract: [cze] [eng]
Je popsána syntéza nových acetylenů, R1C≡CR2, (R1=4-t-butylfenyl; R2=4-[(t- butyl)(difenyl)silyloxy]fenyl; 1-naftyl; 2-naftyl), které byly charakterizovány za použití standardních spektrálních metod. R1C≡CR2 poskytuje při polymerizaci s TaCl5/SnBu4 dobře rozpustné polyacetylenické polymery -[C(R1)=C(R2)]-n. Polymerizovatelnost se zvyšuje s rostoucí přístupností trojné vazby monomeru pro katalyzátor. Výtěžek fotoluminiscence polymerů narůstá v pořadí R2: 1-naftyl < 2- naftyl < 4-[(t-butyl)(difenyl)-silyloxy]fenyl. The synthesis of new acetylenes, R1C≡CR2, (R1=4-t-butylphenyl; R2=4-[(t- butyl)(diphenyl)silyloxy]phenyl; 1-naphthyl; 2-naphthyl) is reported. All monomers were characterized by the means of standard spectroscopic methods. R1C≡CR2 give well soluble polyacetylenic polymers -[C(R1)=C(R2)]-n, in polymerization with TaCl5/SnBu4. Polymerizability increases with increasing monomer triple bond accessibility for the catalyst. The photoluminescence yield of the polymers rises in the R2 order: 1-naphthyl < 2-naphthyl < 4-[(t-butyl)(diphenyl)-silyloxy]phenyl.
