This paper reports on the synthesis and surface immobilization of a 40‐membered chiral salen macrocycle via a surface reaction between its hydroxyl‐terminated branches and a carboxy‐functionalized platform using N,N′‐dicyclohexylcarbodiimide (DCC) as activating molecule of the carboxylic group of 11‐mercaptoundecanoic acid, SAM. The peculiarity of this surface reaction at the carboxy‐terminated platform is that a multiple site esterification is obtained, as indicated by time‐of‐flight secondary ion mass spectrometry measurements.
