“…At the same time, the threshold voltage was reduced from −25 to −12.5 V and the sub-threshold voltage swing decreased from 3.8 to 1.6 V decade −1 for the corresponding devices [31]. This paper reports the electrical characteristics of bottom-gate transistors in which the active semiconductor layer is the spin-coated film of a copper phthalocyanine derivative were substituted with hexyl (C 6 H 13 ) chains at the eight non-peripheral (1,4,8,11,15,18,22,25-) sites as shown in figure 1(a).…”

Solution-processed films of 1,4,8,11,15,18,22,25-octakis(hexyl) copper phthalocyanine (CuPc 6 ) were utilized as an active semiconducting layer in the fabrication of organic field-effect transistors (OFETs) in the bottom-gate configurations using chemical vapour deposited silicon dioxide (SiO 2 ) as gate dielectrics. The surface treatment of the gate dielectric with a self-assembled monolayer of octadecyltrichlorosilane (OTS) resulted in values of 4 × 10 −2 cm 2 V −1 s −1 and 10 6 for saturation mobility and on/off current ratio, respectively. This improvement was accompanied by a shift in the threshold voltage from 3 V for untreated devices to −2 V for OTS treated devices. The trap density at the interface between the gate dielectric and semiconductor decreased by about one order of magnitude after the surface treatment. The transistors with the OTS treated gate dielectrics were more stable over a 30-day period in air than untreated ones.

“…7 It is composed of two plateaus of phthalocyanine (Pc) that sandwich a Lu ion as depicted in Fig. 1, and it has been considered as an interesting material for use as an active medium in gas sensors based on organic field-effect transistors 8,9 and resistors. 10,11 As an active medium its role would be to react with specific gases and through the resulting charge transfer to provide quantitative information about the amount of target molecules present in the environment.…”

“…As a result, electronic coupling between the rare-earth centers in these multiple-decker compounds decreases with an increase in the number of Pc ligands and their magnetic properties start to resemble classic rare-earth double-decker systems. These multipledecker systems, with rare-earth ion size-dependent intramolecular electronic coupling between macrocycles, as well as metal-metal interactions (in the case of multinuclear rare-earth compounds), open potential applications for such compounds in electrochromic modules [30,43,44], gas sensors [30,[44][45][46][47][48][49][50], metal ion sensors [51], and bio-sensors [51][52][53][54], as well as active components of molecular magnets [33,[55][56][57][58][59][60], materials for multi-bit information storage [61][62][63][64], molecular electronics [33,[65][66][67], and non-linear optics [30,[68][69][70].…”

New developments as well as a historic overview on synthetic strategies for preparation of the rare-earth complexes with porphyrins, phthalocyanines, naphthalocyanines, tetraazaporphyrins, and related systems are discussed in detail with emphasis on selective synthetic pathways for preparation of single-, double, and triple-decker architectures. 6 IntroductionAfter their discovery almost 100 years ago, phthalocyanines (Pcs) were predominantly investigated because of their industrial applications as dyes, pigments, and catalysts [1][2][3].Similarly, historically, porphyrins (Pors) were intensively studied because of their importance in mimicking biologically relevant atom-and electron-transfer processes as well as light-harvesting mechanisms associated with living cells [4][5][6]. In addition, porphyrins, phthalocyanines, and their analogues were found to be useful in applications such as redox-driven fluorescence markers and biomarkers, light-harvesting antennas for organic photovoltaics and dye sensitized solar cells, charge carriers for copiers and printers, materials for molecular electronics, as well as redoxactive components in environmental, biological, and industrial sensors as well as active components in photodynamic therapy (PDT) and boron neutron therapy (BNT) of cancer [7][8][9][10][11][12][13][14][15][16][17][18][19].In their initial attempts, researchers focused on rich coordination, redox, and magnetic properties of the metal-free, main-group, and especially transition-metal porphyrinoids. It was soon realized, however, that the rare-earth ions can form unusual systems when coupled with the phthalocyanine ligand.The first rare-earth Pcs were reported by Russian scientists Kirin and Moskalev in 1965 [20]. Kirin and Moskalev also pointed out that because of the large ionic radii and high coordination numbers of the rare-earth ions, the formation of the double-decker rare-earth phthalocyanine compounds could be achieved under specific reaction conditions [20,21]. During the next 50 years, it was confirmed that rare-earth ions are capable of the formation of phthalocyanine single-, double, and triple-decker complexes and their analogues [22][23][24][25][26][27][28][29][30][31][32][33]. One of the interesting recent discoveries was the preparation and characterization of heteronuclear (rareearth / cadmium) multiple-decker complexes, which contain up to six Pc ligands [34][35][36][37][38][39][40][41][42].
