Terbium-containing copolymers based on the norbornene functional derivatives. Synthesis, photoluminescent and electroluminescent properties

New carbazole- and terpyridine- containing norbornene derivatives were synthesized and structurally characterized. On the basis of these compounds by the method of metathesis polymerization copolymers were obtained with carbazole and terpyridine fragments in side chains. The synthesized copolymers react with terbium pyrazolonate complex to form the terbium-containing polymeric materials exhibiting the metalcentered photo- and electroluminescence.

Synthesis and structures of silicon-, germanium-, and tin-containing tungsten carbyne complexes (ButO)3W≡C—EPh3 and [(ButO)3W≡C]2EPh2 (E = Si, Ge, Sn)

New tungsten carbyne complexes (ButO)3W≡C—SiPh3, [(ButO)3W≡C]2SiPh2, [(ButO)3W≡C]2GePh2, and [(ButO)3W≡C]2SnPh2 were prepared by the reactions of (But)6W2 with Ph3SiC≡C—Pr or Ph2E(C≡C—Pr)2 (E = Si, Ge, Sn) in individual crystalline form in 48—80% yields. The structures of both the (ButO)3W≡C—GePh3 and (ButO)3W≡C—SnPh3 compounds synthesized earlier and the new complexes were established by X-ray diffraction analysis.

Synthesis of mixed organotin compounds via dialkylstannyl derivatives of sulphomaleic anhydride

Abstract A few mixed organotin compounds which combine two different organotin moieties (R 2 Sn and R′ 2 Sn or R 2 Sn and R′ 3 Sn) in the same molecule have been synthesized using trialkylstannyl- and new dialkylstannyl derivatives of sulphomaleic anhydride as starting materials.
