Two‐ and Three‐Spin Hybrid Inorganic‐Organic [2]Rotaxanes Containing Metallated Salen Groups
Abstract
Mono- and bis-salen functionalised [2]rotaxanes have been synthesised from the esterification of [2]rotaxanes containing phenol-terminated threads (salen = N,N′-bis(salicylidene)ethylenediamine). The [2]rotaxanes have general formula [RH][Cr<sub>7</sub>NiF<sub>8</sub>(O<sub>2</sub>C<sup><i>t</i></sup>Bu)<sub>16</sub>], where [RH]<sup>+</sup> is a thread with a central secondary ammonium site that templates a [Cr<sub>7</sub>NiF<sub>8</sub>(O<sub>2</sub>C<sup><i>t</i></sup>Bu)<sub>16</sub>]<sup>− </sup>ring. The threads are terminated at one or both ends by carboxylic acid functionalised salen groups. The {M(salen)} groups can be free-base [M = (H+)2] or metallated [M = Cu<sup>2</sup>+, Ni<sup>2+</sup>, (VO)<sup>2+</sup>]. The [2]rotaxanes have been characterised by single crystal XRD and solid- and solution-state EPR spectroscopy. Where two paramagnetic M ions are involved [M = Cu<sup>2+</sup> and/or (VO)<sup>2+</sup>] the [2]rotaxanes contain three electron spin S = ½ centres, since the {Cr<sub>7</sub>Ni} ring has an S = ½ ground state which is well isolated at low temperatures. These three-spin [2]rotaxanes have been characterised in solution by pulsed dipolar EPR spectroscopies (DEER, also known as PELDOR, and RIDME). The M···M and M···{Cr<sub>7</sub>Ni} interactions measured are consistent with dipolar interactions and also with the distances from single crystal XRD.<br/><br/>
