The ionothermal reaction of EuCl₃ with 4,4'-biphenyldicarboxylic acid (H₂BPDC) produced a 3D fluorescence coordination polymer (CP), [PMI]₂[Eu₂(BPDC)₃Cl₂] (1). 1 was dispersed onto the bandage, and further infiltrated by polyvinylidene fluoride (PVDF) to give a mixed matrix 1@PVDF/bandage composite film (1-film). The fluorescence and the morphology indicate 1-film can emit red fluorescence and the CP particles are on the surfaces of bandage fabrics with the adhesion of PVDF. The fluorescence of 1-film can be quenched by different amines in the order of aliphatic amine > aromatic amine > alcohol amine > amide, which concerns with the amine sizes. 1-film shows a fast response and selective sensing to aniline vapor, suggesting it may be a fluorescence turn-off sensor to aniline vapor.

EuCl ₃与4,4'-联苯二甲酸（H ₂ BPDC）进行离子热反应，生成3D荧光配位聚合物（CP）[PMI] ₂ [Eu ₂（BPDC）₃ Cl ₂ ]（1）。将1分散在绷带上，并进一步用聚偏二氟乙烯（PVDF）渗透，得到混合的基质1 @ PVDF /绷带复合膜（1-膜）。荧光和形态表明1-膜可以发出红色荧光，CP颗粒在绷带织物的表面上具有PVDF的粘附力。1-膜的荧光可以由不同的胺按照脂肪胺>芳族胺>醇胺>酰胺的顺序淬灭，这与胺的大小有关。1-film对苯胺蒸气显示出快速响应和选择性感应，表明它可能是对苯胺蒸气的荧光关闭传感器。
