“…In the case of phthalocyanine-based MOFs, fewer examples are available in the literature, but significant progress has been made recently. In recent years, the number of works on their use as active layers of chemiresistive, magnetic, ferroelectric, colorimetric and luminescent sensors has been growing rapidly [ 86 , 87 , 88 ]. It has been shown that hybrid materials including porphyrinoid molecules have better sensitivity and lower detection limits than pristine MOFs.…”

Nitric oxide (NO) is a highly reactive toxic gas that forms as an intermediate compound during the oxidation of ammonia and is used for the manufacture of hydroxylamine in the chemical industry. Moreover, NO is a signaling molecule in many physiological and pathological processes in mammals, as well as a biomarker indicating the course of inflammatory processes in the respiratory tract. For this reason, the detection of NO both in the gas phase and in the aqueous media is an important task. This review analyzes the state of research over the past ten years in the field of applications of phthalocyanines, porphyrins and their hybrid materials as active layers of chemical sensors for the detection of NO, with a primary focus on chemiresistive and electrochemical ones. The first part of the review is devoted to the study of phthalocyanines and porphyrins, as well as their hybrids for the NO detection in aqueous solutions and biological media. The second part presents an analysis of works describing the latest achievements in the field of studied materials as active layers of sensors for the determination of gaseous NO. It is expected that this review will further increase the interest of researchers who are engaged in the current level of evaluation and selection of modern materials for use in the chemical sensing of nitric oxide.

“…Fifth, the relatively high thermal and chemical stability of most MOFs guarantees a long lifetime of MOF‐based sensors. Although recent reviews have discussed either MOF‐based chemical sensors relying on luminescent enhancement/quenching, [ 20,39,40 ] or MOF‐based sensors only relying on the electrical‐transduction mechanism, [ 1b,41–43 ] or open framework materials (including MOFs and covalent organic frameworks) based electronic devices in a broad view, [ 7 ] a comprehensive review focusing on gas sensing of diverse MOF‐based devices based on the latest literature is absent.…”

The ever-increasing concerns over indoor/outdoor air quality, industrial gas leakage, food freshness, and medical diagnosis require miniaturized gas sensors with excellent sensitivity, selectivity, stability, low power consumption, cost-effectiveness, and long lifetime. Metal-organic frameworks (MOFs), featuring structural diversity, large specific surface area, controllable pore size/geometry, and host-guest interactions, hold great promises for fabricating various MOF-based devices for diverse applications including gas sensing. Tremendous progress has been made in the past decade on the fabrication of MOF-based sensors with elevated sensitivity and selectivity toward various analytes due to their preconcentrating and molecule-sieving effects. Although several reviews have recently summarized different aspects of this field, a comprehensive review focusing on MOF-based gas sensors is absent. In this review, the latest advance of MOF-based gas sensors relying on different transduction mechanisms, for example, chemiresistive, capacitive/impedimetric, field-effect transistor or Kelvin probe-based, mass-sensitive, and optical ones are comprehensively summarized. The latest progress for making large-area MOF films essential to the mass-production of relevant gas sensors is also included. The structural and compositional features of MOFs are intentionally correlated with the sensing performance. Challenges and opportunities for the further development and practical applications of MOF-based gas sensors are also given.

“…Es wurde gezeigt, dass die elektrischen und optischen Eigenschaften von orientierungskontrollierten guest@MOF-Schicht oft stark von der Orientierung des eingeschlossenen Gastes abhängen. [7][8][9][10][11][12] Die Materialfunktion kann weiter durch den Grad der Porenfüllung, d. h. durch die Gastbeladung, eingestellt werden, die Berichten zufolge ein entscheidender Faktor für die elektrische Leitfähigkeit, [12,13] die Gasdurchlässigkeit von photoschaltbaren guest@MOF-Materialien, [14,15] oder Photolumineszenz ist. [16,17] Darüber hinaus wurde berichtet, dass strukturelle Veränderungen im MOF-Gerüst aufgrund der Anwesenheit von Gastmolekülen die Photolumineszenz beeinflussen.…”

Anwendungen wie Elektronik, Optik und Gastrennung. Das Zusammenspiel von Schlüsselaspekten der Wirt-Gast-Wechselwirkungen, wie eine quantitative Beschreibung der Gastausrichtung oder die strukturelle Integrität des Wirts als Funktion der Porenfüllung, muss jedoch noch bestimmt werden. Polarisationsabhängige Infrarotspektroskopie in abgeschwächter Totalreflexionskonfiguration in Kombination mit Gassorption ermöglichten es, gleichzeitig die Orientierung des Gastmoleküls und strukturelle Änderungen des MOF-Gerüsts während des Porenfüllprozesses zu untersuchen. Dabei stellten wir fest, dass sich zunächst zufällig orientierte Gastmoleküle mit zunehmender Porenfüllung während der Adsorption aus der Gasphase ausrichten. Gleichzeitig erfährt das Gerüst selbst eine reversible, vom Gastmolekül abhängige Rotation des aromatischen Liganden und einen Prozess der Ligandenablösung, wodurch Defekte induziert werden.
