Multifunctional stimuli-responsive supramolecular polymers have applications in the field of smart materials. Herein, a tri-pillar[5]arene-based multifunctional stimuli-responsive supramolecular polymer network gel (SPN-DTG) was successfully constructed. Interestingly, the SPN-DTG shows excellent conductivity and tunable blue aggregation-induced emission (AIE) properties. Meanwhile, a series of metal-ion-coordinated supramolecular polymer network gels (MSPNs) were successfully constructed by rationally introducing various metal ions into SPN-DTG. The xerogel powder of SPN-DTG shows excellent separation capacity for the removal of Fe3+, Hg2+, Cu2+, and Co2+ from water. More importantly, the Co2+-coordinated supramolecular polymer network gel MSPN-Co shows intriguing thermochromic properties. The color of MSPN-Co could be reversibly controlled between light yellow and dark green by controlling the system temperature. In addition, the Fe3+-, Hg2+-, Cu2+-coordinated supramolecular polymer network gel MSPNs (Mn+ = Fe3+, Hg2+, Cu2+) show high selectivity and quick fluorescence response for I– and H2PO4–. Therefore, the SPN-DTG has applications in multifunctional smart materials with conductivity, AIE, thermochromism, fluorescence detection, and separation properties.

具有导电性，聚集诱导的发射，热致变色，荧光传感和分离特性的基于三支柱[5]芳烃的多功能刺激响应超分子聚合物网络
多功能刺激响应性超分子聚合物在智能材料领域具有应用。本文成功构建了基于三柱[5]芳烃的多功能刺激响应性超分子聚合物网络凝胶（SPN-DTG）。有趣的是，SPN-DTG具有出色的导电性和可调节的蓝色聚集诱导发射（AIE）特性。同时，通过合理地将各种金属离子引入SPN-DTG中，成功构建了一系列金属离子配位的超分子聚合物网络凝胶（MSPNs）。SPN-DTG的干凝胶粉具有优异的分离能力，可去除Fe 3+，Hg 2 +，Cu2+和Co 2+来自水。更重要的是，Co 2+配位的超分子聚合物网络凝胶MSPN-Co表现出令人着迷的热致变色特性。通过控制系统温度，可以将MSPN-Co的颜色可逆地控制在浅黄色和深绿色之间。此外，Fe 3+ -，Hg 2 + -，Cu 2+配位的超分子聚合物网络凝胶MSPNs（M n + = Fe 3+，Hg 2 +，Cu 2+）对I表现出高选择性和快速荧光响应–和H 2PO 4 –。因此，SPN-DTG可用于具有导电性，AIE，热致变色，荧光检测和分离特性的多功能智能材料。
