容易被破坏：带有香豆素基团的新型两亲性嵌段共聚物的胶束通过发色团的双光子吸收对近红外光敏感。在794 nm的照射下，胶束的破坏导致光裂解的香豆素和包封的尼罗红从胶束的疏水核心释放到水溶液中，这导致荧光发射强度的相反变化。
Easily disrupted: Micelles of a new amphiphilic block copolymer that bear coumarin groups are sensitive to near infrared light by two‐photon absorption of the chromophore. Disruption of the micelles under irradiation at 794 nm results in release of both photocleaved coumarin and encapsulated nile red from the hydrophobic core of micelle into aqueous solution, which results in opposing changes in fluorescence emission intensity.
