Aromatic imide-based conjugated dyad polymers: controlling photoinduced electron transfer interaction strength |
| 초록 |
In this study, we have designed and synthesized the three aromatic imide-based novel dyad polymers, which show the different photo-physical properties. These polymers consist of the donor backbone and different imide side chain. The photophysical and electrochemical characteristics of the different dyes have been studied using various techniques including UV-visible absorption and photoluminescence spectroscopy. Among three, BT-PDI polymer performed as an efficient naked eye sensing portable probe for Fe2+ ions and showed “turn-on” fluorescence response with detection limit of picomolar level. This generated BT-PDI polymer Ո Fe2+ complex can be used for the ultrasensitive detection of spermine as in aqueous medium, in urine samples and in the vapor phase. This complex can be established as an efficient portable kit for detection of spermine in terms of a solution-based test kit for real time detection of spermine in vapor released from fermented food samples. |
