Synthesis and Structure of a Dendritic Polysilane

Synthesis and Structure of a Dendritic Polysilane

The first dendritic polysilane, methyl[tris(permethylneopentasilyl)]silane [(Me3Si)3‐SiSiMe2]3SiMe, has been synthesized starting from (Me3Si)3SiH and characterized by crystallography. The dendrimer comprises 27 Si7 pathways and consequently exhibits UV absorption with greatly enhanced intensity ove...

Zusammenfassung:The first dendritic polysilane, methyl[tris(permethylneopentasilyl)]silane [(Me3Si)3‐SiSiMe2]3SiMe, has been synthesized starting from (Me3Si)3SiH and characterized by crystallography. The dendrimer comprises 27 Si7 pathways and consequently exhibits UV absorption with greatly enhanced intensity over that of simple linear polysilanes of similar length.
