Stable controlled release system, conjugated microporous polymers (CMPs) with stimuli‐responsive properties can be ideal structures because their 3D microporous matrix structure and possible stimulated response provide inherent switchable acceptor sites to capture and release guest molecules. Herein, the in situ electrochemical deposition of precursors (DTCzAzo) is utilized to construct highly crosslinked photoresponsive CMP films, which can reversibly undergo the trans‐to‐cis isomerization alternately with irradiation by 355 and 480 nm laser beams. The size of pores in CMP films changes tremendously during the process of trans–cis photoisomerization, to controllably capture, conserve, and release the guest molecules.

电化学沉积控制释放的光响应共轭微孔聚合物薄膜

稳定的控释系统，具有刺激响应特性的共轭微孔聚合物（CMP）可能是理想的结构，因为它们的3D微孔基质结构和可能的受激响应提供了固有的可切换受体位点来捕获和释放来宾分子。本文中，原位电化学沉积前体（DTCzAzo）被用于构建高度交联的光响应CMP膜，其可以可逆地经历的反式-到-顺式异构化交替地照射由355和480nm的激光束。在反式-顺式光异构化过程中，CMP膜中孔的大小发生了巨大变化，从而可控地捕获，保存和释放了客体分子。
