Molecularly Engineered Silica Surfaces with an Assembled Porphyrin Monolayer as Optical NO₂ Molecular Recognizers

Construction of Various Self-assembled Films and Their Application as Lubricant Coatings

“…SAMs have been widely investigated in the past 20 years because of its potential applications in the field of surface modification, boundary lubricant, sensor, photoelectronics, and functional bio-membrane modeling, etc (Foisner et al, 2004;Gulino et al, 2004;Hsu, 2004;Love et al, 2005;Ostuni et al, 1999;Ulman, 1996;. On the basis of the surface chemical reaction and synthetic approaches, the chemical structures of SAMs can be manipulated easily at molecular level.…”

“…Recently, self-assembled nanofilms (SANFs), including self-assembled monolayers (SAMs), self-assembled multilayer films (SAMFs), self-assembled inorganic films (SAIFs) and selfassembled organic-inorganic composite films (SAO-ICFs), have generated substantial interest not only for its simple preparation procedure but also for its wide potential applications in many fields, such as surface modification, boundary lubricant coatings, sensors, photoelectronics, and functional bio-membrane modeling, etc (Foisner et al, 2004;Gulino et al, 2004;Hsu, 2004;Love et al, 2005;Ostuni et al, 1999;Ulman, 1996;. As a potential lubricant film for controlling stiction and friction in micro-/nano-electromechanical systems (MEMS/NEMS), SANFs offers distinct advantages over other strategies for lubrication of MEMS/NEMS devices.…”

Chemical Communication between Metal‐Complex‐Based Monolayers

“…[1,2] During the last three decades, much research has focused on chemically modifying various substrate surfaces with organic monolayers to control the substrate surface properties. [3,4] This approach has led to hybrid organic-inorganic materials with unique electronic/optical and structural properties [5][6][7][8][9][10][11][12][13][14][15] and even to biological model systems. [16][17][18][19] Intermolecular communication within thin films has been explored.…”

Immobilized metalloporphyrins on 3-aminopropyl-functionalized silica support as heterogeneous catalysts for selective oxidation of primary and secondary alcohols

“…Therefore, the supported metalloporphyrins will be more cost-effective [17]. In the past few decades, different kinds of supports such as silica [18][19][20], clay [21], zeolites [22,23], MCM-41 [24,25], and organic polymers [26] have been used for immobilization of metalloporphyrins. Amongst these different supports, silica gel is believed to be one of the most attractive inorganic supports due to its nontoxicity, high stability, good accessibility, low cost, and good surface attraction toward functional groups of organic compounds.…”
