1. A polysiloxane comprising first, second and third repeating units linked together in any order,
wherein the first repeating units are based on first precursors selected from divinyldialkoxysilanes, substituted and unsubstituted vinyldialkoxysilanes, and monosubstituted and unsubstituted dialkoxysilanes, wherein the substituted vinyldialkoxysilanes and the monosubstituted dialkoxysilanes each comprise substituents independently of one another, selected from substituted and unsubstituted alkyl groups and substituted and unsubstituted aryl groups,
the second repeating units are based on second precursors selected from dialkoxysilanes comprising a substituent selected from substituted and unsubstituted alkyl and substituted and unsubstituted aryl groups, and a substituent selected from substituted and unsubstituted polycyclic aromatic hydrocarbon groups,
and the third repeating units are based on third precursors selected from substituted dialkoxysilanes and substituted disilanols each comprising two substituents independently selected from substituted and unsubstituted alkyl groups and substituted and unsubstituted aryl groups.
