Detection of organics using porphyrin embedded nanoporous organosilicas

Highly ordered Nanomaterial Functionalized Copper Schiff Base Framework: Synthesis, Characterization, and Hydrogen Peroxide Decomposition Performance

“…They exhibit highly-ordered porous and size-controlled structures, large specific surface areas, and they also present major accessibility and potential to be functionalized with different functional chemical groups on their surface [5][6][7][8][9][10][11]. Due to their remarkable properties, these catalysts have found a significant variety of applications in catalysis, e.g., gas adsorption [12][13][14][15][16], energy conversion [17,18], organo-optoelectronics [19][20][21][22], energy storage [23,24], gas sensors [25,26], and drug delivery [27][28][29]. A common and very effective procedure for the synthesis of PMOs relates to the co-condensation of silica with precursors such as tetraalkoxysilane and trialkoxyorganosilane in the presence of a structure-directing agent (templating agent), which determines the structure features of the resulting materials.…”

Mesoporous silicas prepared by ammonium perchlorate oxidation and theirs application in the selective adsorption of high explosives

“…Clearly, the adsorption effectiveness depends strongly on the structure of materials utilized. Some mesoporous materials possess high sensitivity, special selectivity, and good stability to explosive adsorbates and are becoming promising candidates for sensor fabrication [30][31][32][33][34][35]. These materials do not suffer from the drawbacks of toxicity, instability, and limited reusability, and are suitable for sensor application.…”

Poly[meso-tetrakis(2-thienyl)porphyrin] for the sensitive electrochemical detection of explosives

“…This, in turn, is reflected in their altered electronic properties. Thus, the porphyrin-explosives interaction has become the basis for the fluorescence detection of nitroaromatic explosives [32][33][34][35]. To incorporate the explosives affinity of porphyrins and their electrocatalytic property within polythiophene, we envisioned that the known thiophenederivatized porphyrin meso-tetrakis(2-thienyl)porphyrin (TTP) can be polymerized to provide a conducting polymer that incorporates porphyrin moieties in its conductive chains [36].…”
