Abstract: The Schiff base <i style="">N,N'</i>-bis(salicylidene)-<i style="">p</i>-phenylenediamine has been complexed with Pt(en)Cl<sub>2</sub> and the resulting Pt<sup>II</sup>-cyclophane, [Pt(en)L]<sub>2</sub>·4PF<sub>6</sub>, reacted with<b style=""> </b>phenol, resorcinol, hydroquinone or benzoquinone in DMSO solution. Their binding has been<b style=""> </b>monitored by the variation in the corresponding UV-visible and emission spectral patterns. The binding properties are compared with the earlier reported Zn<sup>II</sup>-cyclophane [Zn(bpy)L]<sub>2</sub> (bpy = 2,2'-bipyridine). A few solid adducts of phenol and benzoquinone with the Pt<sup>II</sup>-cyclophane complex and hydroquinone as well as that of resorcinol with the Zn-cyclophane have also been synthesized and characterized.
