| 中文摘要 | a novel carbon dot-polyaniline (cd-pani) composite has been successfully synthesized through an efficient one-pot chemical-oxidation polymerization and subsequently applied as a ph responsive material. pani has a role in effectively passivating the cds, which greatly enhances the luminescence intensity of the cds. the ph-switched luminescence and ph sensing properties of the cd-pani composite were investigated via detecting the fluorescence response on changing the solution ph. the switching operation exhibited excellent reversibility, and the luminescence intensity of the cd-pani composite showed linear relationships with the solution ph in the range of 3.50-5.50 and 6.00-12.00. the reasons for the presence of two linear regions on the plot were further discussed in detailed. a probable mechanism was speculated to involve both the conjugation between the cds and pani, as well as the transfer between different pani forms (emeraldine base and emeraldine salt). moreover, oh- ions could serve as the fluorescence quencher of the cd-pani composite. the luminescence intensity of the cd-pani composite displayed a good linear relationship with oh- ions in the concentration range of 5-800 mm. |
