Abstract
Macromolecular compounds having a core-shell structure are described. Also described is a process for preparing such macromolecular compounds, and their use as semiconductors in electronic structural elements.
Claims21
A macromolecular compound, having a core-shell structure, comprising,
- (i) a core comprising a macromolecular base structure comprising atoms selected from the group consisting of silicon and carbon and combinations thereof, said core being bound to at least 3 outer groups by means of, for each outer group,
- (ii) a binding chain based on carbon, each binding chain being bound to said core and also being bound to
- (iii) a first end of a conjugated chain (L) comprising a linear carbon-based oligomeric chain having continuously conjugated double bonds,
- (iv) a further chain that is bound to an end of said conjugated chain (L) that is opposite of said first end of said conjugated chain (L), said further chain being free of conjugated double bonds, and
- (v) a shell comprising said binding chain (ii), said conjugated chain (iii) and said further chain (iv).
