Abstract

This study presents an aggregation-engineering strategy to create tunable, reversible mechanochromic elastomers by doping carboxylated perylene bisimides (PBI) into polyurethane elastomers (TPUs). Additionally, the mechanochromic sensitivity of PBI was found to correlate with the hydrogen bonding strength between TPU and PBI, providing theoretical guidance for anticounterfeiting and sensing applications.

基于苝酰亚胺聚集工程的荧光弹性体的可控机械变色响应。

本研究提出了一种聚合工程策略，通过将羧基苝酰亚胺（PBI）掺杂到聚氨酯弹性体（tpu）中来制造可调的、可逆的机械变色弹性体。此外，发现PBI的机械变色灵敏度与TPU与PBI之间的氢键强度相关，为防伪和传感应用提供了理论指导。
