Abstract

Abstract : A D 3h -symmetry prismatic tris-(ferrocene-1, 1′-diyl) molecular cage has been synthesized and characterized, and the mechanism behind its synthesis has been studied with DFT methods. Abstract : This paper presents a simple, highly selective, and efficient (isolated yield of 68%) synthesis of a novel D 3h -symmetry prismatic tris-(ferrocene-1, 1′-diyl) organic cage (FcB-cage ) by incorporating a boronate ester as a linkage motif. 1, 1′-Diboronated derivatives of ferrocene and 2, 3, 6, 7, 10, 11-hexahydroxytriphenylene (HHTP ) were used as the starting materials. The synthesized cage was comprehensively characterized by spectroscopic and microscopic methods, powder X-ray diffraction, thermogravimetry and voltammetry. Cyclic voltammetry analysis revealed the electronic communication between the ferrocene units of the FcB-cage . In addition, to better understand the mechanism behind the synthesis of such a cage, as well as its geometric properties, we performed DFT calculations.
