Metal-organic frameworks (MOFs) attract much attention because of possibility of designing a structure with a particular pore size/shape, huge porosity and many potential applications [1]. So far, the MOFs, especially, structures that are stable to air or water have been crystallized by hydrothermal or solvothermal syntheses with conventional electrical heating [1]. In this presentation, the crystallizations of MOFs with nonconventional heating methods like ultrasound (US) and microwave (MW) will be discussed. The rapid and facile syntheses of MOFs with US and MW will be presented [2]. Moreover, a phase-selective crystallization of a MOF, especially less stable phase, with MW heating will also be illustrated [3]. The phase-selective crystallization will be explained with phase-conversion to a more stable structure with prolonged crystallization time [3].
