Molecular Orientation of Polydiacetylene Monolayer at the Air-Water Interface

Abstract

Molecular orientation of polydiacetylene monolayers formed at the air-water interface was examined by using fluorescent and polarizing microscopes. We found two different directions of polymerization versus the proper crystallization axis of the monolayer domain. We concluded that the relationship between polymerization and crystal growth is the significant factor for the formation of two different kinds of domains having right and left handed spirals.
