General description

Aluminum isopropoxide is a versatile andinexpensive Lewis acid catalyst and dehydrating agent widely used in the fieldof organic transformations, sol-gel processing, and rechargeable batteries.

Application

Aluminum isopropoxide can be used:
  • As a precursor to synthesize alumina nanoparticles and multimetallic oxides via sol-gel processing.
  • As a catalyst for various organic transformations such as Meerwein–Ponndorf–Verley–Oppenauer (MPVO) reactions and ring-opening polymerization of lactides and lactones.
  • As coating material to fabricate electrodes for lithium-ion batteries toenhance cycling stability and performance.

Thermally activated delayed fluorescence (TADF) materials are inspiring intensive research in optoelectronic applications. To date, most of the TADF materials are limited to metal-organic complexes and organic molecules with lifetimes of several microseconds/milliseconds that are sensitive to oxygen. We report
