“…In addition, the incompatibility between the hydrophilic silica surface and hydrophobic organic molecules severely limits their applications. [ 46–55 ] Therefore, the design and facile synthesis of MCs with well‐defined channel orientation, pore sizes, and pore surface affinities for efficient removal of organic pollutants from water is highly desired and challenging.…”

Highly efficient removal of organic pollutants currently is a main worldwide concern in water treatment, and highly challenging. Here, vertically oriented mesoporous coatings (MCs) with tunable surface properties and pore sizes have been developed via the single‐micelle directing assembly strategy, which show good adsorption performances toward a wide range of organic pollutants. The micelle size and structure can be precisely regulated by oil molecules based on their n‐octanol/water partition coefficients (Log P) in the oil–water diphase assembly system, which are critical to the pore size and pore surface property of the MCs. The affinity and steric effects of the MCs can be on‐demand adjusted, as a result, the MCs show a ultrahigh adsorption capacity (263 mg g−1), surface occupancy ratio (≈41.92%), and adsorption rate (≈10.85 mg g−1 min−1) for microcystin‐LR, which is among the best performances up to date. The MCs also show an excellent universality to remove organic pollutants with different properties. Moreover, overcoming the challenges proposed by particulate absorbents, the MCs are stable and can be easily regenerated and reused without secondary contamination. This work paves a new route to the synthesis of high‐quality MCs for water purification.

“…Many different pendant functional groups has been successfully attached by co-condensation and/or grafting including hydrocarbon groups (e.g., alkyl (Barczak et al 2009a;Li et al 2015), vinyl (Barczak et al 2009bWang et al 2004), phenyl (Barczak et al 2010b;Fan et al 2017;Huang et al 2013)) as well as the groups with complexing properties (amine (Barczak et al 2013;Chong and Zhao 2003;Dobrowolski et al 2013;Zhu et al 2012), thiol (Barczak et al 2016Crudden et al 2005;Liu et al 2000), pyridine (Barczak 2018), carboxyl (Han et al 2007;Shen et al 2008;Tsai et al 2016)). Co-condensation also allows for incorporation of bridged multi-silylated monomers resulting in the so-called periodic mesoporous organosilicas (Asefa et al 1999;Inagaki et al 2002;Mizoshita et al 2011;Yoshina-Ishii et al 1999).…”

Mesoporous organosilicas functionalized simultaneously with both pendant amine groups and ethylene/phenylene bridges, were synthesized to evaluate the effect of the bridges incorporated in the silica framework on the structure, porosity and adsorption properties of final materials. It turned out that the presence of the bridges enhanced the formation of porosity but adversely affected the efficiency of amination. DFT theoretical calculation showed that the amine groups can be partially bonded by phenyl groups of the bridges. The obtained materials were tested as sorbents of diclofenac, which is considered as one of the most prominent hazardous pharmaceuticals. High uptakes of diclofenac reaching 842 mg g −1 proved that the obtained materials could be applied for removal of drugs from waters and wastewaters, particularly when high concentrations of pharmaceutical are considered. For the phenylene bridged-based materials the diclofenac adsorption occurs only in the pores while for the others also on the external surface as indicated by different diclofenac desorption kinetics-this observation can be used to modulate the releasing profiles of drugs via proper design of the surface.

“…36 It should be mentioned here that one of the reasons for the good dispersion of DOP in the PS chain matrix is the π-π interaction between the aromatic ring of DOP and the aromatic ring of the styrene unit. [37][38][39] Figure 4a shows the storage moduli and loss tangents as a function of temperature of PSMANa(6.4) ionomer and ionomers containing ca. 10, 20, 30, and 40 wt% DOP.…”

The plasticization effect by the addition of nonpolar bis(2‐ethylhexyl) phthalate (dioctyl phthalate) (DOP) on the glass transition temperatures (Tgs) of poly(styrene‐Na methacrylate) (PSMANa) ionomers was investigated. The matrix Tg (Tg,m) and cluster Tg (Tg,c) of the ionomers dropped linearly as the DOP content in the PSMANa ionomers enhanced, only when the phase separation of DOP did not occur. Since the Tg,m and Tg,c of the ionomer increased somewhat linearly with increasing ion content of the ionomer, simple equations were obtained to express the Tgs of the ionomers using the ion contents (x mol%) and the DOP contents (y wt%) of the ionomers; Tg,m (°C) = 121 + 3.0x + 2.8y and Tg,c (°C) = 171 + 6.3x + 2.6y. According to the x‐ray scattering results, for the ionomer containing 6.4 mol% of ions, the distance between scattering centers increased from 21 to 22 Å when ca. 40 wt% of DOP was added. This suggested that the DOP promoted the mobility of the styrene chains, enhancing the formation of multiplets. On the other hand, for the ionomer containing 22.4 mol% of ions, when ca. 40 wt% was added, the distance between multiplets widened from 18 to 21 Å.
