要旨

Vinyl-functionalized periodic mesoporous organosilica materials (PMOs) with a crystal-like wall structure were synthesized, for the first time, by direct co-condensation of 1,4-bis(triethoxysilyl)benzene (BTEB) and triethoxyvinylsilane (TEVS). The synthesis approach led to high loading of vinyl functional groups and controlled regular morphologies. The resultant materials with different TEVS contents (up to 60 molar percentage) consisted of well-ordered mesopores (2.82–3.29 nm) with molecular-scale periodicity (7.6 Å) in the walls, so that the high thermal stability of phenylene-bridged organosilica and versatile functionality of vinyl groups are combined. By exploring the influence of TEVS loading and the second monomer, tetraethoxysilane (TEOS), on the molecular-scale regularities, the rule of synergetic assembling of functional monosilylated TEVS and bissilylated BTEB was revealed. That is, the PMOs framework was built up only by BTEB, while TEVS was always terminally bonded to the channels surface.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
