“…Ruthenium phthalocyanines (RuPcs) have been studied for a wide array of applications, including materials chemistry, [1,2] photoelectronics, [3] and photodynamic therapy. [4][5][6] Additionally, RuPc compounds have found utility in a number of electronic devices, perhaps most prominently in organic photovoltaics (OPVs), [7][8][9][10][11] but have also been used in gas sensors, [12][13][14][15] and organic light emitting diodes (OLEDs).…”

“…[22] We hypothesize that the introduction of alkylated substituents provides particularly high solubility in organic solvents, inducing favourable solid state microstructures when deposited, similar to what has been previously observed in other phthalocyanine derivatives. [23] Herein we report the synthesis and characterization of two novel RuPc complexes RuPc(CO)(PyrSiC6) (1) and RuPc(PyrSiC6) 2 (2). The optical and electrochemical properties of each compound were measured and the HOMO and LUMO energy levels estimated (Figure 1b).…”

“…H NMR,13 C NMR, and HRMS of 1 are reported in FigureS3, FigureS4, and FigureS5. Similarly, RuPc(PyrSiC6) 2(2) was obtained from RuPc(PhCN) 2 (4) plus the corresponding pyridine 5 in CHCl 3 , by stirring at room temperature for 18 hrs and following the same purification process by size exclusion chromatography 1. H NMR,13 C NMR, and HRMS of 2 are reported in FigureS6, FigureS7, and Figure S8.…”

Ruthenium phthalocyanine (RuPcs) are multipurpose compounds characterized by their remarkable reactivity and photoelectronic properties, which yield a broad synthetic scope and easy derivatization at the axial position. However, RuPcs have been underexplored for use in organic thin‐film transistors (OTFTs), and therefore new studies are necessary to provide basic insight and a first approach in this new application. Herein, two novel RuPc derivatives, containing axial pyridine substituents with aliphatic chains (RuPc(CO)(PyrSiC6) (1) and RuPc(PyrSiC6)2 (2), were synthesized, characterized, and tested as the organic semiconductor in OTFTs. RuPc thin‐films were characterized by X‐ray diffraction (XRD), and atomic force microscopy (AFM) to assess film morphology and microstructure. 1 displayed comparable p‐type device performance to other phthalocyanine‐based OTFTs of similar design, with an average field effect mobility of 2.08×10−3 cm2 V−1 s−1 in air and 1.36×10−3 cm2 V−1 s−1 in nitrogen, and threshold voltages from −11 V to −20 V. 2 was found to be non‐functional as the semiconductor in the device architecture used, likely as a result of significant differences in thin‐film formation. The results of this work illustrate a promising starting point for future development of RuPc electronic devices, particularly in this new family of OTFTs.
