J.: "Monte Carlo simulation of flexible trimers: From square well chains to amphiphilic primitive models", The Journal of Chemical Physics 139, 114901-1-1/114901-11 (2013), DOI: 10.1063/1.48205300021-96061089-7690 (electrónico)http://hdl.handle.net/10272/17446In this work, we present Monte Carlo computer simulation results of a primitive model of self- assembling system based on a flexible 3-mer chain interacting via square-well interactions. The effect of switching off the attractive interaction in an extreme sphere is analyzed, since the anisotropy in the molecular potential promotes self-organization. Before addressing studies on self-organization it is necessary to know the vapor liquid equilibrium of the system to avoid to confuse self- organization with phase separation. The range of the attractive potential of the model, λ, is kept constant and equal to 1.5σ, where σ is the diameter of a monomer sphere, while the attractive interaction in one of the monomers was gradually turned off until a pure hard body interaction was obtained. We present the vapor-liquid coexistence curves for the different models studied, their critical properties, and the comparison with the SAFT-VR theory prediction [A. Gil-Villegas, A. Galindo, P. J. Whitehead, S. J. Mills, G. Jackson, and A. N. Burgess, J. Chem. Phys. 106, 4168 (1997)]. Evidence of self-assembly for this system is discussed.engAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Square-well chainsAmphiphilic modelMonte CarloVapor-liquid equilibriaStatistical Associating Fluid TheorySAFTFlexible trimer chainsjournal article10.1063/1.4820530open access
