We present an experimental study of a phase transition in a monolayer made of fluorescent amphiphiles. We have combined measurement of surface tension isotherms, ellipsometry and observations by microscopy. We have observed an ordered anisotropic phase coexisting with a liquid phase. The ordered phase is made of elongated domains, whose growth and melting are briefly described.
