Here a ligand exchange strategy for synthesizing sol-gel oxides is demonstrated to achieve multifunctionality including direct photolithography, high dielectric strength, and high charge carrier mobility, which is challenging to obtain in such oxides. For this purpose, a series of bidentate ligands with azide termini and ethylene-glycol bridges is synthesized, and these ligands are universally applicable to the synthesis of a variety of dielectric and semiconductor oxides. Optimized photolithography conditions yield a high-quality ZrO₂ dielectric film with a high dielectric constant and strength of ≈18 and ≈7 MV cm^-1, respectively. Additionally, this strategy is applied to semiconductor oxides such as In₂O₃ and ZnO, and the all-oxide-patterned solution-processed thin-film transistor (TFT) demonstrates a high charge carrier mobility of ≈40 cm² V^-1 s^-1. An oxide TFT array is fully photopatterned on a 4-inch Si wafer; uniform performances are observed across these devices. This study suggests the possibility of realizing multifunctional oxides for application in advanced electronics using simple ligand exchange chemistry.

Polymer Electrolytes In article number 2203413, Chang Yun Son, Moon Jeong Park, and co-workers establish a platform for innovative electrolyte technologies to achieve superionic conduction from solid-state polymer electrolytes. Through the rational design of bifunctional polymers capable of unique intra-monomer hydrogen bonding, interconnected rod-like ion channels are formed in the glassy polymer matrix, which enables a high ionic conductivity of 10−3 S cm−1 and high storage modulus of ca. 100 MPa at 25 °C.
