The control of the energy transfer (FRET) in a novel bischromophoric styryl(pyridinium) dye bearing two different crown ether residues is presented. Complexation of the dye with metal cations allows to tune the FRET efficiency without changing the transfer direction or to switch the FRET off, whereas protonation launches the FRET process in the opposite direction relative to the molecular structure.

双(苯乙烯基)染料-冠醚共轭物的能量转移效率和方向的超分子调节

提出了一种带有两个不同冠醚残基的新型双发色苯乙烯基(吡啶)染料的能量转移(FRET)控制。染料与金属阳离子的络合可以在不改变转移方向的情况下调整FRET效率或关闭FRET,而质子化则在相对于分子结构相反的方向上启动FRET过程。
