Control over the stimuli-responsive behavior of smart molecular systems can influence their capability to execute complex functionalities. Herein, we report the development of a suite of spiropyran-based multi-stimuli-responsive self-assembled platinum(II) macrocycles (5-7), rendering coordination-assisted enhanced photochromism relative to the corresponding ligands. 5 showed shrinking and swelling
Two different molecular switches, a spiropyran and a diarylethene, were attached synthetically to the 5-position of 2′-deoxyuridine. The diarylethene-modified nucleoside can be incorporated synthetically into DNA while preserving its characteristic photochromism.
在 2′-脱氧尿苷的 5 位上合成连接了两种不同的分子开关,一种是螺吡喃,另一种是二芳基噻吩。经二芳基噻吩修饰的核苷可合成到 DNA 中,同时保留其特有的光致变色性。
