Two photoswitchable compounds that can operate under visible light irradiation are prepared and investigated using spectroscopic and computational studies. These all-visible systems are based on the dimethyldihydropyrene (DHP)/cyclophanediene (CPD) photochromic couple connected either to a bipyridine (bpy) unit or to a (tris(bpy)ruthenium(II)) complex through a pyridinium bridge. In these compounds, the DHP to CPD isomerization and the reverse CPD to DHP conversion can be triggered by illumination with red (>630 nm) and blue (460 nm) lights, respectively. The unambiguous and reversible response of these systems triggered by visible light make them potential candidates for biological purposes and electronic devices.
制备了两种可在可见光照射下运行的光开关化合物，并通过光谱和计算研究对其进行了研究。这些全可见光系统基于通过吡啶鎓桥连接到联吡啶（bpy）单元或（三联吡啶钌（II））配合物的二甲基二氢芘（DHP）/环二烯（CPD）光致变色对。在这些化合物中，DHP到CPD的异构化以及CPD到DHP的反向转化可分别由红色（>630 nm）和蓝色（460 nm）光照射触发。这些系统由可见光触发的明确且可逆的响应使其成为生物用途和电子设备的潜在候选者。
