Metal–Organic Framework for Transparent Electronics

Abstract

Electronics allowing for visible light to pass through are attractive, where a key challenge is to make the core functional units transparent. Here, it is shown that transparent electronics can be constructed by epitaxial growth of metal–organic frameworks (MOFs) on single‐layer graphene (SLG) to give a desirable transparency of 95.7% to 550 nm visible light and an electrical conductivity of 4.0 × 104 S m−1. Through lattice and symmetry match, collective alignment of MOF pores and dense packing of MOFs vertically on SLG are achieved, as directly visualized by electron microscopy. These MOF‐on‐SLG constructs are capable of room‐temperature recognition of gas molecules at the ppb level with a linear range from 10 to 108 ppb, providing real‐time gas monitoring function in transparent electronics. The corresponding devices can be fabricated on flexible substrates with large size, 3 × 5 cm, and afford continuous folding for more than 200 times without losing conductivity or transparency.

Electrical conductivity and magnetic bistability in metal–organic frameworks and coordination polymers: charge transport and spin crossover at the nanoscale

“…In this review, we re-examine the different approaches to render MOFs and CPs materials electrically conductive, as well as the strategies to nanostructure and process them as thin films to act as active interfaces in electronic devices. In this sense, various reviews have recently highlighted their potential [23][24][25][26][27][28] centring around the electronic properties of MOFs and CPs. However, most of them miss out on a second relevant property: magnetism, and mostly on the interplay between both electronic and magnetic properties of these materials.…”
