formula trans-Pt(bodipy)I(PEt3)2, where differently substituted bodipydyes attach to the coordination center via a direct Pt–C σ-bond to the pyrrolic carbon atom C2 or C3. We also report an isolable intermediate of the oxidative addition step where the bodipy is η2-bonded to the cis-Pt(0)(PEt3)2 moiety. Comparison between the new complexes, meso-platinated analogue 8-Pt, and the parent dyes reveals that
在这项工作中,我们讨论了五个具有通式反式-Pt(bodipy)I(PEt 3)2的新配合物,其中不同取代的bodipy染料通过直接Pt-Cσ-键与吡咯碳原子C2结合到配位中心。或C3。其中BODIPY是η我们还报告可分离的中间氧化加成步骤的2键合的所述顺式-Pt(0)(PET 3)2部分。新的配合物,内消旋的类似物8-Pt和母体染料之间的比较表明,铂的附着位置会影响光谱,光物理,电化学和电子性质。与之相反8-Pt的吸收带和发射带相对于母体染料发生红移。2-Platinated Bodipy染料2-Pt-6H,2-Pt-6I,2-Pt-Mes-6I和2-Pt-6Et表现出双重荧光和NIR磷光发射,量子产率低,而3-Pt仅发射通过荧光(Φ FL = 52.7%)。该络合物是光化学1 O 2的适度有效敏化剂。生产,但优于亚甲基蓝。如循环伏安法所示,它们还经历一种可逆的单电子还原和氧化。相对于母体染料,半波电势被阴极移动340–510

The Pt(bodipy)-(mercaptopyrene) dyad BPtSPyr shows four different emissions: intense near-infrared phosphorescence (Φph up to 15%) from a charge-transfer state pyrS˙+-Pt-BDP˙−, additional fluorescence and phosphorescence emissions from the 1ππ* and 3ππ* states of the bodipy ligand at r.t., and phosphorescence from the pyrene 3ππ* and the bodipy 3ππ* states in a glassy matrix at 77 K.
