Charge transport mechanism in bis(double-decker lutetium(III) phthalocyanine) (Lu2Pc4) thin film

Synthesis, characterization and investigation of electrical and electrochemical properties of imidazole substituted phthalocyanines

“…7 and 9) are in agreement with the prediction of the CBH model. The same type of temperature dependence for s was observed in other reports in different phthalocyanine films [52,53]. However, at the temperatures T > $438 K, while s values decrease with increasing temperature in high frequency region (x P $1 kHz) as in (T < $438 K), it increases with increasing temperature in low frequency region (x < $1 kHz).…”

“…This model is also not applicable to our results. According to the small polaron quantum-mechanical tunneling (SP) model, the exponent s is an increasing function of temperature [52]. It is also well known that the low values of s indicate multihopping process, while high values of s indicate single hopping process.…”

Pyridone substituted phthalocyanines: Photophysico-chemical properties and TD-DFT calculations

“…Because of their unique spectroscopic and electrochemical properties, metallophthalocyanines (MPc) have found applications as semiconductors, nonlinear optical and optical limiting materials, chemo sensors, organic photovoltaics, catalysis and photo sensitizers for photodynamic therapy and photodynamic inactivation [1][2][3][4][5][6][7][8][9][10][11][12][13]. Pyridone derivatives are hetero cyclic intermediates used for the synthesis of arylazo dyes.…”

Synthesis, characterization and electrochemical properties of novel pyridine phthalocyanine derivatives

“…These complexes display unique physical, spectroscopic and electrochemical properties, since the large conjugated p systems in these complexes are held in close proximity by metal ions [1]. The importance of these complexes in many fields such as optical devices, chemical sensors, semi-conductors, catalysts, non-linear optics, Langmuir-Blodgett films and photodynamic therapy (PDT) has increased rapidly as a result of novel designed compounds [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22].…”
