我们报道了一种π共轭14-卟啉纳米球的模板导向合成。该结构由两个交叉的纳米环组成，含有6个和10个卟啉单元。荧光上转换光谱实验表明，电子激发离域在整个三维π系统在小于0.3 ps，如果纳米球是绑定到它的模板或超过2 ps，如果纳米球是空的。
We report the template-directed synthesis of a pi-conjugated 14-porphyrin nanoball. This structure consists of two intersecting nanorings containing six and 10 porphyrin units. Fluorescence upconversion spectroscopy experiments demonstrate that electronic excitation delocalizes over the whole three-dimensional pi system in less than 0.3 ps if the nanoball is bound to its templates or over 2 ps if the nanoball is empty.
