The crosslinkable trifluoromethylated poly(aryl ethers) terminated with phenylethynyl moieties(11F-PAE-PEP)s were prepared in two step syntheses.

The structure of 11F-PAE-PEP was confirmed by FTIR and 1H NMR. The crosslinking behavior was studied by DSC. There is a remarkable increase of T g after crosslinking of the poly(aryl ethers). The T g values of crosslinked polymers were 437 and 446 K, respectively. The crosslinked polymers could not be soluble in common organic solvents, such as N,N-dimethylformamide, N,N-dimethylacetamide, N-methyl-2-pyrrolidinone, chloroform, and tetrahydrofuran. The temperatures at a 5% mass loss of the crosslinked polymers in air were above 789 K. They showed a good optical property, too. This kind of polymers will be the promising materials used as the microelectronics and optical waveguide devices.展开更多

Typical threshold current is 15mA,with some value as low as 8mA.Output power at 100mA is more than 10mW.The extinction characteristics,modulation bandwidth,and electrical return loss are measured.3dB bandwidth more than 10GHz is monitored.展开更多
