Resumen:

We studied the formation of Langmuir monolayers of two series of amphophilic monodendrons ?-conjugated from first to third generation number with different length of terminal chains C3H7 and C 12H25 the characterization of the monolayer was made through isotherms and images obtained by Brewster Angle Microscopy (BAM) to confirm the phase transition, the six compounds formed Langmuir monolayers stable and reproducible, the stability and homogeneity of the monolayers increases with the increment in the generation number. In addition, we observed that when the length of terminal chains is increases from C3H 7 to C12H25 the stability has a notable increment for the second and third generation number. We had showed that the monodendron the second generation with terminal chains C12H 25 has the best stability and reproducibility.
