    coordination geometry around the iridium center is not a main factor for the emission spectral differences caused by the O^O ancillary ligands. Furthermore, the ancillary ligand effect on the PL properties of the present iridium(III) complexes is independent on solvent polarity and concentrations. Taking these results into consideration, the ancillary ligand effect should be attributed to the electronic

    comprehensive comparative synthetic, structural, electrochemical, and spectroscopic study of an extended series of fluorocarbon-modified iridium(III) complexes. We prepared seven new cationic Ir(III) complexes with tert-butyl isocyanide and trifluoromethyl- or trifluoromethoxy-substituted cyclometalating 2-phenylpyridines, [(C∧N)2Ir(CNtBu)2](CF3SO3), and characterized five of them by crystal structure analysis

    series of cyclometalated iridium(III) complexes has been designed and synthesized, and their photophysical, photochromic, and electrochemical properties have been studied. The X-ray crystal structure of complex 2 has been determined. The emission properties of the complexes have been shown to be readily perturbed through the modification of the electronic properties of the phenylpyridine ligand. With different
    设计并合成了一系列环属化(III)配合物,并研究了它们的光物理,光致变色和电化学性质。配合物2的X射线晶体结构已经确定。已经表明,通过改变苯基吡啶配体的电子性质,可以很容易地扰动配合物的发射性质。在(III)配合物的苯基吡啶配体上具有不同的取代基1(-H),2(-OMe),3(-CHO)和4(-CF 3),它们可以显示出强烈的3MLCT [dπ(Ir)→π*(二亚胺)]发光范围为530 nm至640 nm,跨越绿色到橙色区域。光谱分配也与电化学研究和DFT计算一致。此外,光致变色行为可以容易地通过在C改变取代基调制∧N配体,无需对螺恶嗪骨架进行繁琐的修饰。通过分析反向漂白反应的动力学特征,较少的富电子(III)配合物可以稳定具有较高活化势垒的部花青形式。这些研究不仅为控制这些Ir(III)配合物的通用发光行为的结构-性质关系提供了基本理解,而且为可见光驱动光开关的未来发展提供了分子设计的指导原则。
  • Synthetic Control Over Photoinduced Electron Transfer in Phosphorescence Zinc Sensors

    Despite the promising photofunctionalities, phosphorescent probes have been examined only to a limited extent, and the molecular features that provide convenient handles for controlling the phosphorescence response have yet to be identified. We synthesized a series of phosphorescence zinc sensors based on a cyclometalated heteroleptic Ir(III) complex. The sensor construct includes two anionic cyclo-metalating ligands and a neutral diimine ligand that tethers a di(2-picolyl)amine (DPA) zinc receptor. A series of cyclo-metalating ligands with a range of electron densities and band gap energies were used to create phosphorescence sensors. The sensor series was characterized by variable-temperature steady-state and transient photoluminescence spectroscopy studies, electrochemical measurements, and quantum chemical calculations based on time-dependent density functional theory. The studies demonstrated that the suppression of nonradiative photoinduced electron transfer (PeT) from DPA to the photoexcited Ir-IV species provided the underlying mechanism that governed the phosphorescent response to zinc ions. Importantly, the Coulombic barrier, which was located on either the cyclometalating ligand or the diimine ligand, negligibly influenced the PeT process. Phosphorescence modulation by PeT strictly obeyed the Rehm-Weller principle, and the process occurred in the Marcus-normal region. These findings provide important guidelines for improving sensing performance; an efficient phosphorescence sensor should include a cyclometalating ligand with a wide band gap energy and a deep oxidation potential. Finally, the actions of the sensor were demonstrated by visualizing the intracellular zinc ion distribution in HeLa cells using a confocal laser scanning microscope and a photoluminescence lifetime imaging microscope.
