Two new fluorene derivatized 1,10-phenanthroline ligands and related tris-chelate Ru(II) or Zn(II) coordination complexes have been synthesised. The linear and nonlinear (two-photon induced fluorescence) photophysical measurements have contributed to highlight the possibility to tune the absorption spectral range and excited lifetime, depending on ligand substitution and nature of the metal. More significantly, the observation of two-photon absorption (TPA) associated with long-lived metal-to-ligand charge-transfer (MLCT) excited states in the Ru(II)-based chromophores, opens a wide range of applications in the near infrared.
已经合成了两种新的芴衍生化的1,10 - 菲咯啉配体以及相关的三螯合物Ru(II)或Zn(II)配位络合物。线性和非线性（双光子诱导荧光）光物理测量有助于突出根据配体取代和金属性质来调节吸收光谱范围和激发寿命的可能性。更重要的是，在基于Ru(II)的发色团中观察到与长寿命金属 - 配体电荷转移（MLCT）激发态相关的双光子吸收（TPA），这在近红外领域开辟了广泛的应用。
