A synthetic strategy is developed towards highly amphiphilic cellulose nanocrystals (CNCs) by selectively introducing carboxylic acid groups at the reducing end and –C8 units on the surface. The resulting chloroform soluble CNCs formed an exceptionally stable monolayer at the air/water interface, and resulted in a well-defined LB isotherm, allowing their facile transfer to both hydrophilic and hydrophobic substrates. These monolayers were successfully transferred onto substrates to create monolayer or smooth multilayer films.
