Since the discovery of the crucial role of enediynes in natural antibiotics (such ascalicheamicin, esperamicin, and dynemicin A), enediynes and the Bergman cyclization have attracted fervent attention for many years, especially on small molecule research. In our work, various polymers based on enediynes were designed and synthesized, for example main chain enediyne polymers, compression-responsive polymers and so on. Abilities of DNA cleavage, long term stability of generated radicals and ordered skeleton are the emphasis during our research.<\/p>\n\n\n\n<p><strong>Towards experimental detection of crystallization in individualized polymer chains by dielectric spectroscopy<\/strong><br>Wing-Kit Or<\/p>\n\n\n\n<p>Dielectric spectroscopy is a method to examine changes in density and thus phase transition of crystallization of polymer.
