摘要：

Perovskite-like metal-organic frameworks (MOFs) are hybrid materials of high interest for their potential in information storage technology, as Pb-free substitutes for the widely used lead zirconate titanate (PZT) family of multiferroics. We report here a new, microwave-assisted method of synthesis for perovskite-like MOFs, which exploits the advantages of rapid and volumetric heating by microwaves in order to achieve synthesis within minutes, compared to days required by previously reported methods. The preliminary results demonstrate a broad control over the size and morphology of the products, by minor changes in the reaction conditions. An investigation of the effects of size and morphology on the magnetic and dielectric properties is presented here. (C) 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
