Assembling molecular machines into crystals provides a way to harness their power on large length scales, but the development of a crystal analogue to a molecular motor remains a challenge. The molecule (Z)-5-(anthracen-9-ylmethylene)-3-butylthiazolidine-2,4-dione (C4-ATD) has E and Z isomers with strongly overlapping absorption spectra. This spectroscopic property allows both Z → E and E → Z photoisomerization reactions to be driven by a single light source, and simulations indicate this property can provide a route to robust oscillatory motion. Reprecipitation in an aqueous surfactant enables the growth of single crystal microwires that exhibit continuous mechanical oscillations under a wide range of illumination conditions, including ambient solar irradiation. Molecular crystal motors provide a new approach for transforming continuous light into oscillatory mechanical motion.

基于蒽-噻唑烷二酮光异构化反应的太阳能分子晶体电机

将分子机器组装成晶体提供了一种在大长度尺度上利用其能量的方法，但开发分子马达的晶体类似物仍然是一个挑战。分子 ( Z )-5-(蒽-9-基亚甲基)-3-丁基噻唑烷-2,4-二酮 ( C4-ATD ) 具有E和Z异构体，吸收光谱强烈重叠。这种光谱特性允许Z → E和E → Z光异构化反应由单个光源驱动，模拟表明这种特性可以提供一条实现稳健振荡运动的途径。在水性表面活性剂中的再沉淀能够生长单晶微线，该微线在各种照明条件（包括环境太阳辐射）下表现出连续的机械振荡。分子晶体电机提供了一种将连续光转化为振荡机械运动的新方法。
