Protecting group free one-pot multicomponent Curtius reaction afforded a versatile MN type dendron, ensuring late-stage modification of both dendron and dendrimer to afford highly fluorescent symmetrical and unsymmetrical (Janus) polyurethane dendrimers. Fluorescence study of these dendrimers exhibited the Förster resonance energy transfer (FRET) between blue and mint green fluorophores.
无保护基团的一锅多组分库尔修斯反应得到了一种通用的MN型树枝状分子,确保了树枝状分子和树枝状聚合物的后期修饰,从而得到了高荧光的对称和不对称(雅努斯)聚氨酯树枝状聚合物。这些树枝状聚合物的荧光研究显示了蓝色和薄荷绿荧光团之间的Förster共振能量转移(FRET)。
