基于构筑块导向组装策略设计合成钼红簇合物{Mo49}及其质子传导性能研究
Design and Synthesis of Molybdenum Red Cluster { Mo49 } by Building Block-Directed Assembly for Proton Conduction
摘要
Abstract
Highly reduced molybdenum red(MR)clusters have emerged as a new type of polyoxomolybdates(POMos)and showed great potential as electron/proton reservoirs for energy conversion and storage,as well as for catalysis.However,the limited structural diversity of MR clusters significantly hinders further exploration of their potential as functional materials.Herein,we describe the synthesis of a novel highly reduced MR cluster { Mo49 }(compound 1)based on rational assembly of a variety of basic building blocks(BBs).In addition to the well-established BBs found in the family of MR clusters,the unique tetrahedral { MoⅥ4} BB plays a key role in directing the assembly to afford trigonal pyramid-like structure of compound 1,which consists of 49 Mo and 148 O atoms with a high reduction degree of 73％.Moreover,at 80℃ and 98％relative humidity(RH),the pellet sample of compound 1 displays good proton conductivity of 7.88×10-3 S/cm owing to the efficient hydrogen-bonded network built from the surface oxygen atoms,protons and guest water molecules.This research offers new insights into the assembly and synthesis of MR clusters through a BB strategy and manifests their significant potential for advanced applications.关键词
