Self-assembly, Photopolymerization and Colorimetric Response of a Macrocyclic Diacetylene with Multiple Crown Ether Pendants |
| 초록 |
Recently, self-assembly of polymerizable macrocyclic diacetylenes (MCDAs) has gained a growing interest owing to the possibility of forming intrinsically nanotubular structures. Herein, we report a new crown ether-derived MCDA that displays a unique self-assembly behavior in aqueous solution. The four crown ether-containing macrocycle MCDA-TCE was found to form self-assembled supramolecules in aqueous solution and showed a temperature-dependent aggregation behavior (100 nm at 25 oC and tens of micrometers at 80 oC). Photopolymerization was conducted both at low and at high temperature. Interestingly, the particles in water suspension exhibit a reversible blue-to-purple color change. |
