metal such as platinum(II). We report here, for the first time, the synthesis of three new bimetal compounds containing a gold(III) porphyrin conjugated to a platinum diamine moiety through malonate bridging to obtain enhanced cytotoxicity from both metals combined with the phototoxicity of the porphyrin. The three complexes differ in the type of diamine ligand around platinum(II): ammonia (NH3), cyclohexanediamine

Combining phase-dependent photoluminescence (PL) measurements and quantum chemical calculations is a powerful approach to help understand the influence of the molecular surroundings on the PL properties. Herein, a phosphine functionalized amidinate was used to synthesize a recently presented bimetallic gold complex, featuring an unusual charge separation. The latter was subsequently used as metalloligand

excited-state deactivation of a gold porphyrin (AuP) in porphyrin-based donor−bridge−acceptor (D−B−A) systems has been studied. The results from room temperature and 80 K measurements are presented. The primary objectives have been to investigate whether electrons/electron holes or excitationenergy could be transferred from 3AuP to the appended zinc porphyrin (ZnP) in the dimers. As the bridging chromophores
已经研究了基于卟啉的供体-桥-受体(DB-B-A)系统中金卟啉(AuP)的三重激发态失活。给出了室温和 80 K 测量的结果。主要目标是研究电子/电子空穴或激发能量是否可以从 3AuP 转移到二聚体中附加的锌卟啉 (ZnP)。由于我们的 DB-B-A 系统中的桥接发色团将 ZnP 和 AuP 部分以 19 A 边对边分开,我们预计直接(通过空间)交换机制对电子或能量转移的贡献不大。这使我们有机会仔细研究桥接发色团如何影响转移反应。结果表明,在由完全共轭的桥接发色团连接的二聚体中,3AuP 的猝灭发生效率很高,而当桥的共轭被破坏时,没有观察到猝灭。我们还观察到 3AuP 的衰变在 t...
