Metal–organic frameworks meet polymer brushes: enhanced crystalline film growth induced by macromolecular primers

Abstract

We introduce tailor-made polymeric 3D primers, which produce a striking enhancement in MOF film growth compared to traditional primers.

Nanoarchitectonics of metal organic frameworks and PEDOT layer-by-layer electrodes for boosting oxygen reduction reaction

“…The deposited mass obtained by QCM for a 1x-ZIF-8 film growth cycle is higher than values reported in recent works (see Table S1 for comparison with recently reported methods). 56,66,72,73 This result can be explained by taking into account the high affinity of Zn 2+ ions for the exposed sulfonate moieties present in the PEDOT:PSS layer. It has been demonstrated, the interactions between MOF precursors and surface-exposed moieties are crucial to manipulate the dynamics of film growth.…”

“…56 Moreover, Bindini et al showed that the use of a sulfonate-bearing polyelectrolyte brush as anchoring platform (a 3d-primer rather than a surface confined 2D-primer) increased the amount of ZIF-8 deposited compared to what could be expected from a sulfonate-terminated SAM. 73 In that work, it was stated that the brushes contain…”

Synthesis and characterization of thermoresponsive ZIF-8@PNIPAm-co-MAA microgel composites with enhanced performance as an adsorption/release platform

“…The fact that no additional particles with different size distribution were observed suggest that heterogeneous nucleation within the microgel is greatly enhanced over homogeneous ZIF-8 nucleation. 20 Further evidence of the suggested confined growth can be obtained from DLS autocorrelation curves ( Fig. 1a , inset).…”

3D‐Stretched Film Ni3S2 Nanosheet/Macromolecule Anthraquinone Derivative Polymers for Electrocatalytic Overall Water Splitting

“…[ 2,9,10 ] Because of the chemical stability, thermal stability and highly adjustable photoelectric properties, as carriers of catalyst, this kind of carbon material have been used for electrochemical applications such as OWS, oxygen evolution reaction (OER), carbon dioxide reduction, and hydrogen evolution reaction (HER). [ 11,12 ] The study also shows that the macrocyclic carbon framework material enhances the crystallization ability of ZIF‐8, [ 13 ] which solves the problem of low crystallinity of metal organic frameworks prepared by traditional benzene derivatives (BZD). As a significant natural and synthetic compound with a macrocyclic skeleton structure, anthraquinone derivatives (AQD) are particularly attractive because they can be extracted from plants, which means economical and environmentally friendly.…”
