“…This reflects that the dioxane intake is highest among toxic organic solvents. Since the dioxane and its derivatives penetrates fast to ground water, we propose that the material C2B can be utilized for the removal of dioxane as waste from contaminated water . To prove our proposal, aqueous samples of DMF and dioxane were prepared at different percentage ratio with water.…”

Motivated with the continued demand for developing quality material showing better response for the efficient removal of organo-amphiphilic toxicants, we have demonstrated the growth of three-dimensional polymer organic framework-a covalent crosslinked polymer C2B derived via photon triggered thiol-alkene click reaction.Instrumentation techniques such as nuclear magnetic resonance, thermogravimetric analysis, and fourier transform infrared spectroscopy were used for the characterization. FESEM and Cryo-SEM analysis were done to analyze the morphology of the resin. The adsorption and release experiments were done with ultraviolet-visible spectroscopic technique. The polymer C2B derived from polyolefin and tetrathiol via thiol-alkene photoclick reaction showed efficiency toward adsorption of organoamphiphilic contaminants such as dioxane, dimethylformamide, fluorescein, and rhodamine B (RH). Even the material selectively showed the efficient release of toxicant-RH. Moreover, it can be reused over cycles. This makes the polymer C2B as potential candidate to be commercially viable for textile industries.

“…Further, the PXRD pattern reveals the amorphous nature of the material (Figure S2). This might be due to the irreversible kinetic control during the polymerisation process of HMP‐TAPA, which resulted in disorderly growth of polymeric network [5i] . The stability of synthesised HMP‐TAPA was determined by TGA analysis in nitrogen atmosphere.…”

A heptazine-based microporous polymeric network, HMP-TAPA was synthesised by direct coupling of trichloroheptazine and tris(4-aminophenyl)amine (TAPA). A high surface area of 424 m 2 /g was achieved, which is the highest surface area among heptazine-based polymeric networks (HMPs). The tailored electron-donor and -acceptor units in HMP-TAPA give broad visible-light absorption. HMP-TAPA was employed as metal-free photocatalyst for oxidative coupling of amines to imines under visible light irradiation with 98 % selectivity. Furthermore, the surface basicity of HMP-TAPA was used to achieve metal-free heterogeneous base catalysis for Knoevenagel condensation under base-free conditions with > 99 % conversion. In addition, HMP-TAPA showed extreme robustness over a wide pH range (1-14). The versatility and flexibility of the current material design is beneficial for understanding its photoactivity and surface basicity so as to design dual active (photo)catalyst materials for specific applications.

“…The quenching mechanism was proposed by Cao et al,, could be applied here to explain the fluorescence quenching. The mechanism of Fe 3+ ion quenching of MCP‐2 in this work could be due to the stronger interactions between Fe 3+ ions and Lewis base sites in MCP‐2 compared with Cu 2+ , Hg 2+ ions and other metal ions as well . MCPs contain N/S atom show the similar recognition ability might be agreed with Cao's theory.…”

Micro/mesoporous conjugated polymers (MCPs) incorporate fluorescence, adsorption, and electronic conductivity together were synthesized. In this paper, a family of MCPs was prepared by Suzuki–Miyaura coupling‐reaction using different building blocks. MCPs were studied by Fourier Transform infrared spectroscopy (FTIR), solid‐state 13C Nuclear magnetic resonance (13CNMR) spectra, fluorescence spectra, Ultraviolet–visible spectroscopy (UV‐vis), scanning electron microscope (SEM), and Brunauer–Emmett–Teller (BET). The as‐prepared MCPs are of porous structure and fluorescence. The pore diameters and specific surface areas varied by changing the starting monomers. The MCPs could be linear chain and network structure depending on the starting monomers. The specific surface areas of network MCPs are larger than linear chain ones. The fluorescence MCPs could be employed as chemosensors for detection of metal ions. Also the MCPs could be used as adsorbent for separation of metal ions and organic dyes. The maximum absorption capacity of MCP‐4 for Fe3+ ions reached 152 mg/g within 30 min. Meanwhile, when MCPs were used for the removal of organic dyes, the adsorption capability of MCP‐4 reached 488 mg/g and 491 mg/g for methylene blue (MB) and rhodamine (RhB) within 30 min respectively. With the introduction of N, S atoms to the building blocks, the sensing and removal ability were enhanced. Furthermore, the MCP family owns electric conductivity which may be employed as solar cell materials.
