Lanthanide (Yb(3+), Nd(3+)) complexes equipped with red-absorbing hydroporphyrin (chlorin) antennae were synthesized and characterized. The syntheses are scalable, highly modular, and enable the introduction of different chlorins functionalized with a single reactive group (COOH or NH(2)). Absorption maxima were dependent on chlorin substitution pattern (monomeso aryl or dimeso aryl) and metalation state (free base or zinc chelate). The complexes benefit from dual chlorin (610-639 nm) and lanthanide (980 or 1065 nm for Yb- or Nd-complexes, respectively) emission in the biologically relevant red and near IR region of the spectrum.
合成并表征了具有红色吸收氢卟啉（叶绿素）天线的镧系（Yb(3+)，Nd(3+)）配合物。这些合成方法具有可扩展性、高度模块化的特点，并能够引入不同的叶绿素，这些叶绿素都用单个反应基团（COOH 或 NH(2)）进行了功能化。吸收最大值取决于叶绿素的取代模式（单甲川基或二甲川基）和金属化状态（自由碱基或锌螯合物）。这些配合物在生物相关的光谱的红色和近红外区域中受益于双叶绿素（610-639nm）和镧系元素（Yb 配合物为 980nm，Nd 配合物为 1065nm）的发射。
