    Abstract

    A novel wet water–ethanol‐borne technique of preparing nanocrystals of the poly[5,7‐dodecadiyn‐1,12‐diol bis‐(n‐butoxycarbonylmethyl urethane)], oxoreferred to as poly(4‐BCMU), is reported for the first time. The fabrication of poly(4‐BCMU) nanocrystals with sizes ranging from a few to hundreds of namometers is presented. The spectroscopic analysis of the poly(4‐BCMU) nanocrystals using nuclear magnetic resonance, infrared, optical absorption spectroscopy, gel permeation chromatography and scanning electron microscopic techniques is discussed. A structural characterization at molecular level of the poly(4‐BCMU) constituting the nanocrystals evidences the maintenance of the molecular integrity of the polydiacetylene backbone.
