PARAMAGNETIC CHARGE TRANSFER COMPLEXES - NEW MOLECULAR COMPOSITES VIA INTERCALATION OF THIAZOLE AND BENZOTHIAZOLE DERIVATIVES WITHIN THE CAVITIES OF THE 3D HOST POLYMERS [(ME(3)E)(3)FE(CN)(6)](INFINITY) - E=SN OR PB

摘要

The three-dimensional (3D) polymers [(Me(3)Sn)(3)Fe(CN)(6)](infinity) (I) and [(Me(3)pb)(3)Fe(CN)(6)](infinity) (II) which have wide internal cavities capable of incapsulating voluminous organic compounds behave as host accepters forming charge transfer complexes (CTC). Thiazole and benzothiazole derivatives acting as guest donor species are encapsulated within the cavities of the 3D polymeric hosts I or II forming yellow to green or red CTC having, in some cases, semiconducting properties. Some of the donors containing an amino group undergo polymerization within the cavities of the host polymers forming new molecular composites having pronounced electrical conductivity when doped in 2 M HCl solution. The interesting feature of these composites is the enhanced electronic conductivities exhibited by encapsulation of the conductive polymers within the cavities of the host 3D polymers.
