Photo-Induced Phase Transitions to Liquid Crystal Phases: Influence of the Chain Length from C(8)E(4) to C(14)E(4)

Photo-induced phase transitions are characterized by the transformation from phase A to phase B through the absorption of photons. We have investigated the mechanism of the photo-induced phase transitions of four different ternary systems C(i)E(4)/alkane (i) with n = 8, 10, 12, 14; cyclohexane/H(2)O...

description Photo-induced phase transitions are characterized by the transformation from phase A to phase B through the absorption of photons. We have investigated the mechanism of the photo-induced phase transitions of four different ternary systems C(i)E(4)/alkane (i) with n = 8, 10, 12, 14; cyclohexane/H(2)O. We were interested in understanding the effect of chain length increase on the dynamics of transformation from the microemulsion phase to the liquid crystal phase. Applying light pump (pulse)/x-ray probe (pulse) techniques, we could demonstrate that entropy and diffusion control are the driving forces for the kind of phase transition investigated.
