Block-like microcrystals composed of cis-dimethyl-2(3-(anthracen-9-yl)allylidene)malonate are grown from aqueous surfactant solutions. A pulse of 405 nm light converts a fraction of molecules to the trans isomer, creating an amorphous mixed layer that peels off the parent crystal. This photoinduced delamination can be repeated multiple times on the same block.
由顺式-二甲基-2(3-(蒽-9-基)亚烯基)丙二酸酯组成的块状微晶从水相表面活性剂溶液中生长出来。405nm 光脉冲将部分分子转化为反式异构体,形成无定形混合层,从母体晶体上剥离下来。同一块晶体上可以多次重复这种光诱导的分层。
