The Cover Feature illustrates the fluorescence photoactivation of polymer nanoparticles doped with a BODIPY–oxazine dyad in alginate hydrogel beads. The photoinduced dissociation of the oxazine ring brings the BODIPY chromophore in conjugation with an indole auxochrome in the photochemical product to shift its absorption and emission bands bathochromically. These spectral changes allow the excitation of reactant and product at same wavelength and the collection of their emissions in partially‐resolved spectral windows. The photocleavable oxazine component can be substituted with styryl groups to regulate the absorption properties without preventing photoactivation. More information can be found in the Article by F. M Raymo and co‐workers on page 332 in Issue 5, 2020 (DOI: 10.1002/cptc.201900276).

封面人物：光活化BODIPY-恶嗪二元化合物结构修饰的合成策略（ChemPhotoChem 5/2020）

封面功能说明了藻酸盐水凝胶珠粒中掺有BODIPY-恶嗪二聚体的聚合物纳米颗粒的荧光光活化作用。恶嗪环的光致离解使BODIPY生色团与光化学产物中的吲哚类辅助色素共轭，从而通过红移改变其吸收和发射谱带。这些光谱变化允许在相同波长激发反应物和产物，并在部分分辨的光谱窗口中收集它们的发射。可光裂解的恶嗪组分可被苯乙烯基取代以调节吸收性能而不会阻止光活化。有关更多信息，请参见2020年第5期的F.M Raymo及其同事在第332页上的文章（DOI：10.1002 / cptc.201900276）。
