This invention relates to organic functional thin films, specifically to a method for growing controllable number of
layers using
solvent vapor-assisted growth. p A method for preparing MSB molecular
crystal thin films, and the application of these films in generating
superoxide ions under
light irradiation for antibacterial protection. This method addresses the limitations of existing solution
drop casting epitaxy methods for preparing... p To address the problems of uncontrollable layer number, limited area, and insufficient reactive
oxygen generation efficiency in MSB molecular
crystal thin films, this invention utilizes
toluene vapor atmospheres of varying concentrations to control the
solvent evaporation rate, thereby achieving... p The few-layer, large-area, and uniform growth of MSB molecular
crystal thin films allows for the regulation of molecular arrangement and
electronic structure, promoting
electron localization and efficient
electron transfer to
oxygen molecules under illumination, thus significantly improving the generation efficiency and stability of
superoxide ions.
