摘要

A number of 3D-coordination polymers, constructed via [~dM(CN)_6] building blocks and (Me_3E) connecting units, have been prepared and characterized by X-ray powder diffraction and different spectroscopic methods. 1-Methyl-4-(4'-R-styryl) or (2'-R-styryl) pyridinium cations (stp) have been successfully encapsulated within the expandable wide channels of the 3D-coordination polymers by tribochemical or ion exchange reactions producing novel molecular composites. Apart from 6, [(4'-OCH_3-stp)(Me_3Sn)_3Fe~(II)(CN)_6-MeOH]_(infinity) which exhibits thermochromic behaviour, the molecular composites [(stp)_x(Me_3E)_3Fe_(1-x)~(III)Fe_x~(II)(CN)_6]_(infinity), 1-12 are mixed valence materials exhibiting localized interaction between the mixed valence iron. The results indicated an ion charge transfer interaction between the guest stp-cations and the host matrix. The molecular composites [(stp)(Me_3E)_3 M~(II)(CN)_6]_(infinity), 13-18 are due to the facile readiness of the coordination polymers [(Me_3E)_4M(CN)_6]_(infinity) and [(Et__4N)(Me_3Sn)_3Fe(CN_6)]_(infinity) to ion exchange.
