摘要

<正>The synthesis and characterization of coil-rod-coil triblock oligomers

poly（ethylene oxide）-b-p-hexaphenyl-b-poly（ethylene oxide）

are described. The number of repeating ethylene oxide units in each flexible block are 3 （EO3-PHP-EO3）

8 （EO8-PHP-EO8）

13 （EO13-PHP-EO13）

and 17 （EO17-PHP-EO17）

respectively. The structures of these oligomers are confirmed by 1H-NMR

13C-NMR

and MALDI-TOF mass spectrometry. The introduction of soluble poly（ethylene oxide） coils to the rigid p-hexaphenyl segment significantly improves the solubility of the oligomers

so they can form smooth thin films by spin-coating from their solutions. The oligomers are quite thermally stable and have 1% weight loss temperatures at above 340℃under nitrogen. They can emit strong blue light in both solution and film state

and have fluorescence quantum yields of about 40% in chloroform. They are expected to have potential applications in optoelectronic devices.
