A mixed matrix Eu-4,4′-biphenyldicarboxylate coordination polymer film as a fluorescence turn-off sensor to aniline vapor

Publication date: January 2019Source: Journal of Solid State Chemistry, Volume 269Author(s): Mei Lin Shen, Zhen Wei, Ling Xu, Bing Liu, Huan JiaoAbstractThe 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.Graphical abstractA MOF composite film acts as a fluorescence turn-off sensor to aniline vapor with fast response and selectivity.
