准一维有机半导体hepta（p-phenylene vinylene）（HPV）使用共价策略并入DNA张紧整体三角形基序中。通过合理设计从HPV-DNA伪菱形边缘自组装3D阵列，并通过X射线衍射表征。以DNA基序为模板，HPV分子以8 mM的浓度作为单分子荧光发射体存在于晶格内。 HPV-DNA晶体的各向异性荧光发射表明HPV分子在宏观3D DNA晶格中排列良好。从DNA构建的复杂的纳米器件和功能材料可以从这个策略通过解决功能组件与分子的准确性。
A quasi‐one‐dimensional organic semiconductor, hepta(p‐phenylene vinylene) (HPV), was incorporated into a DNA tensegrity triangle motif using a covalent strategy. 3D arrays were self‐assembled from an HPV‐DNA pseudo‐rhombohedron edge by rational design and characterized by X‐ray diffraction. Templated by the DNA motif, HPV molecules exist as single‐molecule fluorescence emitters at the concentration of 8 mM within the crystal lattice. The anisotropic fluorescence emission from HPV‐DNA crystals indicates HPV molecules are well aligned in the macroscopic 3D DNA lattices. Sophisticated nanodevices and functional materials constructed from DNA can be developed from this strategy by addressing functional components with molecular accuracy.
