© 2020 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim To diversify metal-organic frameworks (MOFs), multi-component MOFs constructed from more than two kinds of bridging ligand have been actively investigated due to the high degree of design freedom afforded by the combination of multiple ligands. Predicting the synthesis conditions for such MOFs requires an understanding of the crystallization mechanism, which has so far remained elusive. In this context, microflow systems are efficient tools for capturing non-equilibrium states as they facilitate precise and efficient mixing with reaction times that correspond to the distance from the mixing point, thus enabling reliable control of non-equilibrium crystallization processes. Herein, we prepared coordination polymers with pillared-layer structures and observed the intermediates in the syntheses with an in-situ measurement system that combines microflow reaction with UV/Vis and X-ray absorption fine-structure spectroscopies, thereby enabling their rapid nucleation to be monitored. Based on the results, a three-step nonclassical nucleation mechanism involving two kinds of intermediate is proposed.

We describe a simple bottom-up strategy to generate [Au(SPh)] (SPh: thiophenolate) coordination polymer (CP) based thin films by employing an interfacial self-assembly on a nylon substrate. This method utilizes Au ion-doped nylon film as a precursor of [Au(SPh)] CP and a support substrate to control the kinetics of the reduction of the Au ion from Au(III) to Au(I) and the complexation of Au(I) ions as well as SPh on the surface of the nylon film. The obtained CPs exhibit a fibril morphology with high crystallinity, which leads to a luminescent property. Further, we systematically study the formation mechanism of [Au(SPh)] CPs on the substrates. Amorphous CPs formed at an early stage of reaction are transformed to crystalline CPs based on the rearrangement of components during the reaction. The findings described herein offer novel and interesting openings for the synthesis of Au ion-based CPs that demonstrate desired functions for a wide range of applications. n n n
