Abstract

Abstract: Crystalline Li–organic thin films are grown with the atomic/molecular layer deposition (ALD/MLD) technique from lithium hexamethyldisilazide and hydroquinone. The as‐deposited films are found to undergo a reversible structural transformation upon exposure to ambient humid air. According to density functional theory calculations, the guest‐induced transformation may be related to an unsaturated Li site in the crystal structure. Abstract : From vapors to hybrid thin films : Atomic/molecular layer deposition allows the layer‐by‐layer vapor‐phase growth of highly crystalline coordination polymer thin films. Benefiting from the unsaturated metal sites the novel lithium aryloxide structure is capable of reversibly reacting with guest molecules (see figure).
