Static And Dynamic Studies In Nonyloxycyanobiphenyl (9ocb) Confined To Anopore Membranes

We analyze and compare the static and dynamic properties of alkoxycyanobiphenyl (9OCB). This compound exhibits an I-N-SmA phase sequence. After confining into Anopore structures several phenomena can be seen: Both phase transitions change in their nature, C$_{p}$ peaks becoming lower, broader and shifted down in temperatures. A possible first-to-second order transition could be determined for the N-SmA. There developes a surface induced nematic layer that becomes larger when temperature decreases. Molecular dynamics out from the nematic layer is quite similar to that of the bulk.
