NOx sensitivity of monomeric and polymeric N-macrocyclic compounds

Noncovalent Functionalization of Single-Wall Carbon Nanotubes for the Elaboration of Gas Sensor Dedicated to BTX Type Gases: The Case of Toluene

“…In the field of chemical sensors, phthalocyanines and porphyrins as well as their metal derivatives have been extensively used as sensing materials. − As shown in Figure a, upon toluene exposure, the QCM sensors made of CuPctBu and OEPH 2 present a frequency decrease (i.e., mass increase). According to our experiments, all MC-based QCM mass sensors show responses in the range 400–1200 ppm toluene.…”

Physical–Chemical Properties of Self-Assembled Structures in Solution of Zinc Phthalocyanine and Bis-3-pentyl-PTCDI Derivative

“…By careful substitutions, the unique structural and physical properties have made these molecules important, in various areas of material science, such as semiconductors, molecular electronics, optoelectronics, photonics, photovoltaics, electrochromic, liquid crystal applications, and catalysis. − These compounds are also used in the active sites of enzymes, which are responsible for catalytic reactions such as aerobic oxidation, reduction and transport of dioxygen, and destruction of peroxides . The metallophthalocyanine complexes are promising in a variety of high-tech fields, such as nonlinear optics, , optical data storage, display devices as electrochromic substances, and gas sensors for the detection of halogens such as chlorine and nitrogen dioxide, as well as organic vapor analysers. − Special derivatives of phthalocyanines are used as second-generation photosensitizers for photodynamic therapy (PDT) of cancer as they show strong absorption in the visible to near-IR region (600–850 nm), possessing greater tissue penetration properties and satisfactory photosensitization of singlet oxygen …”

Chemical and electrochemical synthesis of conducting graft copolymer of vinyl acetate with pyrrole and studies of its gas and vapor sensing

“…The family of PPy materials can be used for biosensors, 13 chemosensors, 14 electronic devices, 15 and as solid electrolytes in rechargeable batteries. 16 Preliminary investigations to employ these polymers as sensitive materials for gas sensors 17 have been promising and more detailed studies are in progress.…”
