Studies of the stability properties of 2-docosylamino-5-nitropyridine monol
ayers have shown that three-dimensional structures are formed from the mono
layer material over a wide surface pressure region between 2 and 25 mN m(-1
) Constant surface pressure relaxation experiments are analysed on the basi
s of the nucleation growth theory. Under all conditions the experimental re
sults are described by the instantaneous nucleation mechanism with edge gro
wth for the 2D/3D transformation process. This is different to the progress
ive nucleation so far observed for the other amphiphilic monolayers. (C) 19
