最后关头:光漂白动力学表明,在单分子水平上,直接连接的卟啉阵列(见图)的激子离域长度约为4或5个卟啉单元。这一结果提供了一个更好的理解光信号传输发生在固态,并给出了卟啉阵列作为单分子光子线的前景。
Down to the wire: Photobleaching dynamics show the exciton delocalization length of directly linked porphyrin arrays (see picture) to be about four or five porphyrin units at the single-molecule level. This result provides a better understanding of how light-signal transmission occurs in the solid state and gives a perspective for the porphyrin arrays to be used as single-molecule photonic wires.
