oxidized complexes indicate ligand‐centered radicals. The copper ions of the paddle‐wheel core are strongly antiferromagnetic coupled. DFT calculations for the fully oxidized complexes indicate a very weak ferromagnetic coupling between the copper ions and the ligand radicals, whereas a very weak antiferromagnetic coupling is found among the ligand radicals.
A triad D-Ir-A, where Ir is an Ir(III) bisterpyridine complex connected through an amidophenyl spacer to D, a triphenylamine electron donor, and to A, a naphthalene bisimide electron acceptor, has been synthesized and electrochemicallyinvestigated. The photoinduced processes in the triad, which is more than 4-nm long, have been characterized by steady-state and time-resolved optical spectroscopy by

The straightforward synthesis of three organotinclusters endowed with six triarylamine-based moieties is reported herein. The optoelectronic properties of the molecules, as well as their ability to form gels, were investigated. The association ability of the compounds was studied as well by means of variable temperature nuclear magnetic resonance (NMR) and ultraviolet–visible (UV–vis) spectroscopy
本文报道了具有六个基于三芳胺的部分的三个有机锡簇的直接合成。研究了分子的光电特性以及它们形成凝胶的能力。还通过变温核磁共振 (NMR) 和紫外-可见 (UV-vis) 光谱研究了化合物的缔合能力。已对化合物的几何形状进行了优化,并与晶体的 X 射线衍射进行了比较。通过这种比较获得的结果有助于解释它们不同的凝胶行为。事实上,有机锡氧鼓1表现出通过许多非共价短接触形成有组织的超分子结构的强大能力,最终在芳香族溶剂中产生发光的有机凝胶。
A Triphenylamine/Bis(terpyridine)Ir

Dyad for the Assembly of Charge‐Separation Constructs with Improved Performances
A new dyad DII-Ir consisting of a triphenylamine donor and a bis(terpyridine)IrIII acceptor separated by a bridge composed of two benzamide groups has been synthesized. The electrochemical and photophysical properties of the dyad have been compared to those of a corresponding dyad D-Ir characterized by a bridge connecting the donor and the acceptor consisting of a single benzamide unit. We show that
