Studies of Cyclic and Linear Polydimethylsiloxanes. XXVI. An Investigation of the Mobility of Cyclic Polydimethylsiloxane in the Melt Through the Excimer Emission of Small Probes

Intramolecular excimer formation of 10,10'-diphenyl-bis-9-anthrylmethyl oxide as well as of meso-2,4-di(N-carbazoly)pentane in a cyclic polydimethylsiloxane has been investigated. It is shown that the rate of conformational change of the probes contains an intramolecular component in addition t...

Zusammenfassung:Intramolecular excimer formation of 10,10'-diphenyl-bis-9-anthrylmethyl oxide as well as of meso-2,4-di(N-carbazoly)pentane in a cyclic polydimethylsiloxane has been investigated. It is shown that the rate of conformational change of the probes contains an intramolecular component in addition to that of the local chain dynamics. 19 ref.--AA
