Polymerization-Induced Emission

This article highlights the recent developments of unorthodox luminescent polymers without large p-conjugated structure and their luminescence mechanism in last 2–3 years. Non-conjugated luminescent polymers (NCLPs) will be a wonderful polymer that will provide new soft luminescent materials. Uniting polymer synthesis and photophysical science, Polymerization-Induced Emission (PIE) is proposed for making NCLPs because the advanced polymerization methods have unlimited opportunities to the development of new soft luminescent polymers owing to the multi-level structures of polymers. The importance of this paper is to inspire more thoughts on the emission mechanism of the non-conjugated polymers and developing new soft luminescent materials.
