通过将双光子捕获三芳胺天线与热稳定的邻氟偶氮苯衍生物共价连接，实现了双nir光子触发的偶氮苯的Z -> E异构化。通过单光子和双光子激发，所获得的光开关分别可以被可见光和近红外光完全寻址，后者提供了增强的穿透深度和提高的空间分辨率。
Two-NIR-photon-triggered Z -> E isomerization of an azobenzene was accomplished by covalently linking a two-photon-harvesting triarylamine antenna to a thermally stable ortho-fluorinated azobenzene derivative. The obtained photo-switch is fully addressable with visible and NIR light by using one-photon and two-photon excitation, respectively, with the latter offering enhanced penetration depth and improved spatial resolution.
