Polydiynes with Aggregation-Enhanced Emission Characteristics: Synthesis and Superamplified Detection of Explosives

摘要

Organic polymers with useful materials properties have been under constant pursuit for many decades, since the groundbreaking discovery of the high electric conductivity of doped polyacetylene. Organic π-conjugated polymers are well-known as semiconductors and are important materials in electronic and photonic devices. A wide range of applications spreading from polymeric light-emitting diodes, plastic lasers, polymers-based photovoltaic cells are envisioned or already realized.2 Among the semiconducting organic polymers such as polyenes, polydiacetylenes and polytriacetylenes, polyynes remain the most synthetically challenging and difficult to study.~3
