| 英文摘要 | herein, we report for the first time the use of bipyridine-based hydrogel for selective and visible detection and absorption of cd2+. at low concentrations, hydrogelator 1 was applied for selective detection of cd2+ in vitro and in living cells with high sensitivity. in the absence of metal ions, 1 is nonfluorescent at 470 nm. upon addition of metal ions, 1 selectively coordinates to cd2+, causing an 86-fold increase of fluorescence intensity at 470 nm via the chelation enhanced fluorescence (chef) effect, as revealed by first-principles simulations. at 1.5 wt% and ph 5.5, 1 self-assembles into nanofibers to form hydrogel gel i. since cd2+ could actively participate in the hydrogelation and promote the self-assembly, we also successfully applied gel i for visible detection and absorption of cd2+. with these excellent properties, gel i is expected to be explored as one type of versatile biomaterial for not only environmental monitoring but also for pollution treatment in the near future. |
