“…[24] As far as we know, only PMO materials containing a bridging phenyl group with additional side chains are known, which are difficult to modify further. [25][26][27] Therefore, the organic-inorganic derivative 1,3-bis-(trialkoxysilyl)-5-bromobenzene (1) represents a tempting compound and is reported here for the first time.…”

An interesting class of materials is mesoporous organosilica materials containing a bridging, organic group along the pore‐surface. Such materials are prepared from silsesquioxane precursors of the type (R′O)3Si‐R‐Si(OR′)3 where R is the bridging organic group of interest, in combination with a lyotropic phase as a template for the generation of the pores. A new silsesquioxane precursor, 1,3‐bis‐(trialkoxysilyl)‐5‐bromobenzene, and the related mesoporous organosilica material containing bromobenzene groups located at the pore walls are presented in the current publication. The latter precursor allows access to the derivatization reactions known for halogenated aromatic compounds. Materials containing phenyl derivatives can be obtained either by chemical modifications starting from the mentioned precursor on the molecular scale, or the modifications can be performed directly at the surfaces of the porous material. Materials with surfaces containing benzoic acid, styrene, and phenylphosphonic acid are described.

“…58 Periodic mesoporous organosilicas with aryl groups such as tolyl, xylyl, and dimethoxyphenyl derived under acidic conditions in the presence of cetylpyridinium chloride showed an indication of aryl-silica ordering in the channel walls. 42 The other material that showed little atomic-scale periodicity is ethenylene (-CH=CH-) bridging organosilica.…”

“…21b Temtsin et al also reported the mesophases from 2-methylbenzene-1,4-bis(triethoxysilyl), 2,5-dimethylbenzene-1,4-bis(triethoxysilyl), and 2,5-dimethoxybenzene-1,4-bis(triethoxysilyl) precursors using hexadecylpyridinium chloride as the surfactant under acidic conditions and also by adding ammonium fluoride as the catalyst after neutralization. 42 Goto and Inagaki have summarized the synthesis of mesoporous phenylene-silica with large pores ranging from 6.0 to 7.4 nm in diameter using pluronic P123, a triblock copolymer surfactant. 43 In another very recent development, Kapoor et al have reported the detailed synthesis of average-pore phenylene-bridged mesoporous materials in the presence of oligomeric Brij-56 and Brij-76 surfactant templates under acidic conditions.…”

The latest developments in periodic mesoporous organosilicas (PMO) have been compiled. The discovery of mesoporous hybrid organosilicas with molecular scale periodicity resulting from alternating hydrophilic and hydrophobic layers, and a cost effective solution showing the use of allyl derivatives of the bis-silyl precursors are discussed. Relevant uses of the periodic mesoporous materials in diverse applications are summarized. For example, the metal-incorporated periodic mesoporous organic frameworks are likely to offer an advantage in catalytic transformations, while the functionalized PMOs show promise in fascinating catalytic applications via enhancing the physical properties of guest molecules and clusters. In general, the advancement in PMOs have showed great promise and are expected to deliver exciting achievable future findings.

“…75 As early as 2001, before the first synthesis of the ''true'' crystal-like PMOs by Inagaki et al 1 some degree of molecular-scale ordering has been found in the pore walls with aryl groups such as tolyl, xylyl, and dimethoxyphenyl derived. 31 Interestingly, Inagaki and coworkers recently found that the molecularscale regularity of PMO pore walls can be generated by a post alkaline solution treatment of the amorphous mesoporous phenylenesilicas derived from triblock copolymer P123 under acidic conditions. 58 It is implied that the formation of molecular-scale regularity and mesostructured ordering are mutually independent processes.…”

Periodic mesoporous organosilicas (PMOs) represent a promising new class of organic–inorganic nanocomposite materials in which the organic and inorganic moieties are covalently linked and homogeneously distributed at molecular level. This review retrospected the discovery and development of PMOs in terms of rational synthesis based on the concept of supramolecular self‐assembly. The main focus is on precursors and crystal‐like PMOs. We also highlight the recent achievements regarding compositions and mesostructures, morphologies, and applications in the field. Furthermore, we present an outlook about the promising future perspectives of PMOs that result from the latest developments.
