Route 3: Other

main p.6 · Methods: Transfer method

SolventsCH2Cl2/aqueous interface
AtmosphereArgon inherited from reaction setup where applicable
Substrate orientationSubstrate immersed into the reaction solution and passed horizontally and slowly through the CH2Cl2/aqueous interface after film formation.
Work-upAqueous solution removed before substrate was taken out of CH2Cl2.

Route 4: Other

main p.6 · Methods: Transfer method

SolventsCH2Cl2/aqueous interface
AtmosphereArgon inherited from reaction setup where applicable
Substrate orientationSubstrate settled horizontally in reaction container before adding reaction solutions; solution surface about 10 mm higher than substrate; subphase removed so interface passes through substrate.
Work-upFilm deposited with upside-up orientation on substrate.
