Topochemical Polymerization of a Diarylbutadiyne Derivative in the Gel and Solid States Jules Roméo Néabo Késhia Imelda Sika Tohoundjona Jean-Francois Morin 10.1021/ol200051m.s001 https://acs.figshare.com/articles/journal_contribution/Topochemical_Polymerization_of_a_Diarylbutadiyne_Derivative_in_the_Gel_and_Solid_States/2681965 A diarylbutadiyne derivative was synthesized using a few steps and gelified in aromatic solvents. The gel prepared at low concentration is made of micrometers-long nanofibrils as shown by scanning electron microscopy. XRD of the dried gel shows sharp features, revealing a well-organized material. A topochemical reaction was performed on the dried gel, and a polydiacetylene presenting reversible thermochromism properties was obtained. 2011-03-18 00:00:00 thermochromism properties Topochemical Polymerization topochemical reaction XRD scanning electron microscopy Solid StatesA diarylbutadiyne gel
