摘　　要：Conjugated microporous polymers(CMPs)are a kind of porous skeleton polymers,which are characterized by extended conjugated skeletons,large specific surface area and structure stability.In this work,a facile and versatile method was developed to fabricate flexible conjugated microporous polymer films for fast detecting the total quantity of developing agents and their oxidation products.Conjugated microporous polymer films were synthesized through in situ one-step approach by Suzuki coupling reaction.With such merits such as intense luminescence,easy synthesis and disposability,the polymer films were employed to detect developers based on fluorescence quenching in the printing wastewater.A linear response to p-benzoquinone,oxidation product of developers,was obtained in the range of 0.05-0.5 lmolL-1,with a detection limit of 0.015 lmolL-1.The strategy for in situ growth of flexible polyphenylene-conjugated microporous polymer(PP-CMP)films seems to be a very portable and general method for meeting different analytic purposes.
