Synthesis, Structure and Photoluminescence of A potential Luminescent Material of Mn(II) Coordination Polymer

摘要

A new coordination polymer [Mn_3(IP)(4,4'-obb)_3]_n (1) (4,4'-obb = 4,4'-Oxybisbenzoic acid, IP = 1H-imidazo[4,5-f][1,10]-phenanthroline) was synthesized and characterized by IR, elemental analysis and X-ray diffraction. Single-crystal X-ray analyses revealed that the compound demonstrates 1D structure in which the Mn~(2+) centers are connected via 4,4'-obb anions into 1D chain, the chains are further connected via hydrogen - bonding and π ... π interactions. In addition, the photoluminescence for compound 1 is also investigated in the solid state at room temperature.
