| 中文摘要 | an anionic water-soluble polyfluorene derivative, poly(9,9-bis(6'-phosphatehexyl)fluorene-alt-1,4-phenylene) sodium salt (pfhpna), was synthesized by suzuki coupling reaction in dmf/water. polymer pfhpna was well soluble in water with a strong blue fluorescence emission. effect of the side chain length on fluorescence sensory properties was studied by comparing quenching efficiencies toward different quenchers of pfhpna with a reported polymer poly(9,9-bis(3'-phosphatepropyl)fluorene-alt-1,4-phenylene) sodium salt (pfppna), which have different side chains in length. for small molecular quenchers (methylviologen, mv2+) and meso-5,10,15,20-tetrakis-(n-methyl-4-pyridyl)porphine (tmpyp4), polymer pfhpna had lower sensitivity due to the much longer side chain length. the positively charged metalloprotein cytochrome c could quench fluorescence of conjugated polymers via energy transfer and electron transfer. |
