    • Metallocorrole complexes of third row transition metals (see Formula I below) may be used as therapeutic agents, catalysts, components of oxygen detectors, and components of light emitting diodes. In particular, metallocorrole complexes of third row transition metals may be used as improved photosenitizers in photodynamic therapy; as improved catalysts in aziridination, epoxidation, and water splitting reactions; as improved in vivo imaging agents; and as improved components in the emissive layer of OLEDs. Due to their strongly sigma-donating nature, corroles are able to stabilize third row transition metals in high oxidation states. Third row transition metals are significantly more electropositive than their first and second row counterparts and may therefore act as improved catalysts. In addition, the high spin-orbit coupling constants of third row transition metals may lead to easier singlet-triplet inter-system crossing in the excited state, which in turn may allow for long-wavelength phosphorescence that is desirable for many applications.
    • 可以使用第三排过渡金属的金属络合物(参见下面的式I)作为治疗剂,催化剂,氧检测器的组分和发光二极管的组分。 特别地,第三排过渡金属的金属络合物可用作光动力疗法中的改进的光敏剂; 作为氮丙啶化,环氧化和水分解反应中改进的催化剂; 作为改进的体内成像剂; 并且作为OLED的发射层中的改进的组分。 由于它们具有强烈的西格玛特性,因此腐蚀能够稳定高氧化态的第三排过渡金属。 第三排过渡金属比其第一和第二排对应物显着更多的正电性,因此可以用作改进的催化剂。 此外,第三行过渡金属的高自旋轨道耦合常数可能导致在激发态下更容易的单线 - 三线态跨系统交叉,这又可能允许对于许多应用是期望的长波长磷光。
