“…Compared to p1 and p2, the p3 shows a large redox peak because of the partial overlap with redox peak of 3,3′-bicarbazolyl units. The structural characterizations of organometallic polymers assembled on solid surface have been a challenge 32,33 . We found that the dimer already got worse solubility with time and gradually precipitated from the solution ( Supplementary Figs.…”

Single rich-stimuli-responsive organometallic polymers are considered to be the candidate for ultrahigh information storage and anti-counterfeiting security. However, their controllable synthesis has been an unsolved challenge. Here, we report the rapidly sequence-controlled electrosynthesis of organometallic polymers with exquisite insertion of multiple and distinct monomers. Electrosynthesis relies on the use of oxidative and reductive CC couplings with the respective reaction time of 1 min. Single-monomer-precision propagation does not need protecting and deprotecting steps used in solid-phase synthesis, while enabling the uniform synthesis and sequence-defined possibilities monitored by both UV-vis spectra and cyclic voltammetry. Highly efficient electrosynthesis possessing potentially automated production can incorporate an amount of available metal and ligand species into a single organometallic polymer with complex architectures and functional versatility, which is proposed to have ultrahigh information storage and anti-counterfeiting security with low-cost coding and decoding processes at the single organometallic polymer level.

“…This prevents nanosheets from stacking vertically, ensuring that the MOFs/COFs can only grow in the confined 2D interface region, which can lead to the formation of nanosheets. According to the synthesis methods of nanosheets at different interfaces, they are mainly divided into liquid–liquid, liquid–gas, liquid–solid and so on …”

Metal–organic framework (MOF) and covalent organic framework (COF) nanosheets are a new type of two‐dimensional (2D) materials with unique design principles and various synthesis methods. They are considered ideal electrochemical devices due to the ultrathin thickness, easily tunable molecular structure, large porosity and other unique properties. There are two common methods to synthesize 2D MOF/COF nanosheets: bottom‐up and top‐down. The top‐down strategy mainly includes ultrasonic assisted exfoliation, electrochemical exfoliation and mechanical exfoliation. Another strategy mainly includes interface synthesis, modulation synthesis, surfactant‐assisted synthesis. In this Review, the development of ultrathin 2D nanosheets in the field of electrochemistry (supercapacitors, batteries, oxygen reduction, and hydrogen evolution) is introduced, and their unique dimensional advantages are highlighted.

“…We previously reported that the planar Fe(tpy) 2 CONASH film on an ITO electrode undergoes rapid and durable electrochromism 34 ; the color changed reversibly between purple and pale yellow for [Fe(tpy) 2 ] 2+ and [Fe(tpy) 2 ] 3+ , respectively. In the present study, we observed a similar color change ( Fig.…”

Two-dimensional coordination nanosheets (CONASHs) are grown at the spherical liquid–liquid interface of a dichloromethane droplet in water to form zero-dimensional nano- and micro-capsules using a simple dropping method, a syringe-pump method, and an emulsion method. Reaction of 1,3,5-tris[4-(4′-2,2′:6′,2″-terpyridyl)phenyl]benzene (1) with Fe(BF4)2 affords electrochromic Fe(tpy)2 CONASH capsules and that of ligand 1 with ZnSO4 does photoluminescent Zn2(μ-O2SO2)2(tpy)2 CONASH capsules. Fe(tpy)2 CONASH capsules containing magnetite particles were produced by the syringe-pump method by adding magnetite to the aqueous phase, with the assembly and dispersion of the magnetite-containing CONASH capsules being easily controlled with a magnet. This indicates that physicochemically functional CONASH capsules are suitable for incorporating other functional materials to develop hybrid systems.
