Based on the correlation between MD simulations and experimental results, we analyzed the effect of the end alkyl chain in linear bisazo dye molecules upon the uniaxial orientational degree (S) of their oriented thin films deposited on aligned PTFE layers. Medium end chains such as n-butyl bring about high S and we have just clarified the molecular mechanism for that.
