We have successfully prepared stable one-layer films of 54COOBC [Formula Presented]-pentyl-[Formula Presented]-pentanoyloxy biphenyl-4-carboxylate] in a small film hole [Formula Presented] mm in diameter) and conducted high-resolution optical reflectance measurements near the smectic-[Formula Presented]–hexatic-[Formula Presented] transition. The stability of these films is contrary to experiences with all other compounds and also to heuristic understanding. We propose a modification to such understanding. Within the resolution of our measurements, data are in good agreement with those of two-layer films. The result gives a confirmation of two-dimensional behavior of two-layer films.
