Lutetium bisphthalocyanine thin films as sensors for volatile organic components (VOCs) of aromas

Synthesis, characterization and VOCs adsorption kinetics of diethylstilbestrol-substituted metallophthalocyanines

“…Pcs as a group of potential gas sensing materials, have become a natural choice for the detection of VOCs because of their open coordination sites for axial ligation, their large spectral shifts upon ligand binding and their intense coloration [19]. Previous investigations on Pc thin films as gas sensing materials have revealed a high sensitivity to the various organic vapors [5,[20][21][22][23][24]. Unlike the ensign properties and the effect of environmental conditions on the sensing performance of Pc-based sensors, adsorption kinetics of organic vapors on novel metallophthalocyanine thin films have not been widely studied.…”

Influence of the morphology of platinum combined with β-Ga2O3 on the VOC response of work function type sensors

“…Besides, there is the request to measure at room temperature in order to avoid cracking the VOC and to allow for using a low energy sensor for the implementation of wireless sensor networks. In the past, various sensitive materials have been investigated, like metaloporphyrines [1], aluminates [2], perovskites [3], metal oxides [4][5][6], polymers [7][8][9], phtalocyanines [10] and catalysts [11], to name only a few. This paper relates to work function based sensors and contributes to low-temperature VOC detection.…”

Characterization and organic vapor sensing properties of Langmuir–Blodgett film using a new three oxygen-linked phthalocyanine incorporating lutetium

“…In the last decade, the possible application of Pc thin films as sensors for atmospheric gaseous pollutants has been extensively studied [4][5][6]. Unfortunately, the response of the thin films of Pc towards VOCs has not been so extensively studied [7]. Basova et al [6] Pc material is used as a sensing element against chloroform and benzene vapors.…”

“…The introduction of different central metal ions into Pc compound turns out to be powerful means of modifying the chemical and physical properties of phyhalocyanines [8]. The bisphthalocyanine of lutetium (LuPc 2 ) is an attractive material for the detection of VOCs due to its high sensitivity, fast response times, repeatability and the variety of responses it produces and the sensitive layers was used for several months without significant loses in sensitivity [7]. Pc 2 Lu with a high concentration of intrinsic charge carriers and a low-thermal activation energy of conduction is used as a sensitive element of a gas sensor using HCl, Cl 2 , H 2 S, NO 2 and SO 2 [3].…”
