Abstract

Hexadentate ligand L and its Ln(3+) complexes EuLCl3 (1), TbLCl3 (2), SmLCl3 (3) are synthesised. All these complexes are well characterized for their photophysical properties such as luminescence lifetime decay(τ) and overall quantum yield(Φ). These complexes being water soluble, depicts their intense metal centred luminescence. Effect of pH on these complexes suggest that their emission intensities are stable in the pH range 4-9 and show their compatibility to function in the physiological pH. Graphical Abstract Normalized emisson spectra of complex 1, 2 and 3 (1x10(-5)M) in HEPES Buffer at pH 7.4 (λexc=276nm).

摘要

合成了六齿配体L及其Ln(3+)配合物EuLCl3（1）、TbLCl3（2）、SmLCl3（3）。所有这些配合物均通过发光寿命衰减(τ)和总量子产率(Φ)等光物理性质得到了充分表征。这些配合物具有水溶性，呈现出强烈的以金属为中心的发光。pH对这些配合物的影响表明，它们的发射强度在pH值4-9范围内稳定，显示出它们在生理pH值下发挥作用的兼容性。图形摘要：配合物1、2和3（1x10(-5)M）在pH 7.4的HEPES缓冲液中的归一化发射光谱（λexc=276nm）。
