Exploring routes to visible-light-driven rotary motors, the possibility of red-shifting the excitation wavelength of molecular motors by extension of the aromatic core is studied. Introducing a dibenzofluorenyl moiety in a standard molecular motor resulted in red-shifting of the absorption spectrum. UV/vis and 1H NMR spectroscopy showed that these motors could be isomerized with light of wavelengths up to 490 nm and that the structural modification did not impair the anticipated rotary behavior. Extension of the aromatic core is therefore a suitable strategy to apply in pursuit of visible-light-driven molecular motors.

具有扩展芳香核的分子马达的可见光激发



在探索可见光驱动旋转电机的路线中,研究了通过芳香核延伸来红移分子电机激发波长的可能性。在标准分子马达中引入二苯并芴基部分导致吸收光谱红移。 UV/vis 和1 H NMR 光谱表明,这些电机可以用波长高达 490 nm 的光进行异构化,并且结构修饰不会损害预期的旋转行为。因此,芳香核的延伸是追求可见光驱动分子马达的合适策略。
