An OTFT based on titanium phthalocyanine dichloride: A new p-type organic semiconductor

Influence of the Coordinated Ligand on the Optical and Electrical Properties in Titanium Phthalocyanine-Based Active Films for Photovoltaics

“…Along with the already-mentioned Pcs with metallic atoms, there are also phthalocyanines with titanium tetravalent configuration, such as titanyl phthalocyanine (TiOPc) and titanium phthalocyanine dichloride (TiCl 2 Pc) [ 15 , 16 , 17 ]. They show a p-type transport characteristic, which makes them act as semiconductors.…”

“…Apparently, a relationship between the charge carrier transport type and their axial ligand also exists. The TiCl 2 Pc has a p-type transport characteristic, where both the axial ligands and the electronegativity of the metal influence the LUMO energy and the charge distribution [ 15 ]. The TiCl 2 Pc exhibits emission efficiencies enough to be considered as potential infrared emitters [ 15 , 17 ].…”

The TiCl 2 Pc exhibits emission efficiencies enough to be considered as potential infrared emitters [ 15 , 17 ]. On the other hand, the TiOPc also presents a p-type transport characteristic and it is known to be one of the organic materials that exhibits the largest photo-carrier generation efficiency, which has been successfully tested in laser-printer technologies [ 13 , 14 , 16 , 17 ].…”

Impedance Spectroscopy and Dielectric Relaxation of Imidazole-Substituted Palladium(II) Phthalocyanine (ImPdPc) for Organic Solar Cells

“…Many studies on the modified phthalocyanine with various central metal atoms and chemical substitution have been at the focus of multidisciplinary interests ranging from photodynamic therapy in cancer treatment 15 to pigments such as the blue- and green-color filters of liquid crystal displays (LCDs), 16 and as organic thin-film transistors (OTFTs). 17 Moreover, phthalocyanines offer tremendous possibilities for the development of field-effected transistors whose charge carrier mobility greatly exceeds 1 cm 2 V –1 s –1 , 18 an improvement in the power conversion efficiency of the solar cell larger than 5%, 19 and also for pollution monitoring as smart sensors. 20 Consequently, significant interest has been generated for the study of the electrical properties of Pc compounds and their derivatives.…”

Synthesis and electrochemical properties of copper(II), manganese(III) phthalocyanines bearing chalcone groups at peripheral or nonperipheral positions

“…Since pthalocyanines (Pcs) have chemical, thermal stability and  electron system, they have been very important derivatives for researchers [1]. In addition to its usage as paint, phthalocyanines are preferred as functional materials for different technological areas such as electrochemical sensors [2,3], solar cell [4,5], gas sensors [6,7], non-linear optics [8], semiconductors [9,10], liquid crystals [11,12], photovoltaics [13], catalysts [14], electrochromic [15,16], photosensitizer in photodynamic therapy (PDT) [17][18][19].…”
