Designing a New Class of Mechanophoric Polymer Based on Epoxy‐Functionalized Rhodamine Derivative

Abstract

Mechanophoric polymers are an interesting class of smart polymers which contain a special force‐sensitive molecular motif that can lead to a chemical change within the polymer network in response to mechanical force. This investigation reports the design of a mechanophoric polymer based on epoxy‐functionalized rhodamine via a monomeric approach. In this case, rhodamine was modified with glycidyl methacrylate (GMA) through an epoxy‐amine reaction to design a vinyl‐functionalized multi‐armed macromonomer (Rh‐GMA) which was reacted with butyl acrylate (BA) to prepare the crosslinked polymeric film. The crosslinked polymeric film demonstrated mechanophoric properties under UV and stretching conditions.This article is protected by copyright. All rights reserved
