The near-infrared two-photon absorption (TPA) spectra of a series of cyclometalated iridium complexes have been measured. These complexes exhibit moderately large TPA cross-sections of approximately 20 GM at the biological relevant wavelength of 800 nm. A new complex has been designed and synthesised, and found to have an increased cross-section of 44 GM at 800 nm. Full photophysical characterisation of this complex is presented.
已经测量了一系列金属环配合铱配合物的近红外双光子吸收（TPA）光谱。这些配合物在生物相关的 800nm 波长处表现出约 20GM 的中等大小的 TPA 截面。设计并合成了一种新的配合物，发现其在 800nm 处的截面增加到 44GM。呈现了该配合物的完整光物理特性。
