Energy input plays a crucial role in the assembling of matter. In our present study, we utilize EDC as a chemical fuel to drive the molecular assembling of POR-COOH. POR-COOH will react with EDC to generate the intermediate POR-COOEDC first, which was well-solvated by solvent molecules. During the subsequent hydrolysis process, EDU and oversaturated POR-COOH molecules at high energy states will be formed and thus allowed the self-assembling of POR-COOH into 2D nanosheets. This chemical energy assisted assembling process could be performed not only under mild conditions with high spatial accuracy but also with high selectivity in complex environments.
能量输入在物质组装过程中起着至关重要的作用。在我们目前的研究中,我们利用EDC作为化学燃料来驱动POR - COOH的分子组装。POR - COOH首先会与EDC反应生成中间体POR - COOEDC,它被溶剂分子良好地溶剂化。在随后的水解过程中,会形成EDU和处于高能量状态的过饱和POR - COOH分子,从而使POR - COOH自组装成二维纳米片。这种化学能量辅助的组装过程不仅可以在温和条件下以高空间精度进行,而且在复杂环境中具有高选择性。
