“…Nonlinear SV plots with k q values in the range from 40 to 400 Pa −1 s −1 for the more sensitive component have also been observed in other works on mesostructured materials MCM-41 [ 38 – 43 ] and SBA-15 [ 13 , 39 – 41 , 43 ] that incorporated indicators of different classes including Ru(II) [ 13 , 39 ], Cu(I) [ 40 , 42 ], and dirhenium [ 41 ] complexes as well as metalloporphyrins [ 13 , 38 , 43 ]. This literature indicates that SBA-15 appears to give significantly more sensitive materials with K SV and k q being 2–6 times higher than compared to MCM-41.…”

The review provides comparison of porous materials that act as a matrix for luminescent oxygen indicators. These include silica-gels, sol–gel materials based on silica and organically modified silica (Ormosils), aerogels, electrospun polymeric nanofibers, metal–organic frameworks, anodized alumina, and various other microstructured sensor matrices. The influence of material structure and composition on the efficiency of oxygen quenching and dynamic response times is compared and the advantages and disadvantages of the materials are summarized to give a guide for design and practical application of sensors with desired sensitivity and response time.

“…Haitao et al [88] recently constructed an optical sensor based on the sensitivity to oxygen of a novel Cu(I) complex: [Cu(PTO)(PPh 3 ) 2 ]BF 4 98 , which was embedded in mesoporous silica matrix. The photo-hysical properties of the complex are reported, in dichloromethane solution, in Table 5; the lifetime under pure nitrogen was found to be 64.4 μs which sharply decreases to 2.5 μs under 100 % O 2 suggesting quite good sensitivity.…”

Continuous monitoring of oxygen concentration is of great importance in many different areas of research which range from medical applications to food packaging. In the last three decades, significant progress has been made in the field of optical sensing technology and this review will highlight the one inherent to the development of oxygen indicators. The first section outlines the bioanalytical fields in which optical oxygen sensors have been applied. The second section gives the reader a comprehensive summary of the existing oxygen indicators with a critical highlight on their photophysical and sensing properties. Altogether, this review is meant to give the potential user a guide to select the most suitable oxygen indicator for the particular application of interest.

“…From amongst several families of mesoporous silica materials (MPS) already developed and used in sensor applications, it is worth mentioning the more typical MCM [19,32,33,36,39,42,[58][59][60][61][62][63][64][65], SBA [21-28, 34, 35, 45, 48, 58, 60, 66], HOM [20,36,[43][44][45][46]67], HMS [29,38]. Lamellar MCM-50 [107,108] The structures of the more studied mesoporous materials for sensor applications are presented in Figure 1.…”

Heavy metal pollution is one of the more serious environmental problems; therefore, there is a constant demand for the development of new analytical tools for its monitoring. An optical chemical sensor represents a good alternative to classical instrumental methods. The mesoporous materials used in optical chemical sensors' fabrications have properties such as high porosity, exceptional adsorption capacity, tuneable 3D shape, geometry, and morphology, which enable improved limit of detection, response time, and selectivity properties of optical sensors. In this review, we firstly present the properties of mesoporous materials, provide a brief description of sensing mechanisms, and briefly discuss the importance of continuous monitoring. Recent advances in those mesoporous silica-based optical sensors used for heavy metal detection have been reported and their advantages and limitations also discussed. This review covers publications that have appeared since 2008.
