Synthesis, characterization, electrochemical, spectroelectrochemical and dye-sensitized solar cell properties of Phthalocyanines Containing Carboxylic Acid Anchoring Groups as photosensitizer

Effects of anchoring and spacer groups of asymmetric zinc phthalocyanines on the photovoltaic performance of dye-sensitized solar cells

“…DSSC measurements were completed by following the procedures provided in the literature. 24 Detailed electrochemical and DSSC measurement procedures are given in the ESI †. First of all, a TiO 2 paste was applied to the clean surface of FTO glass (active square area: 25 mm 2 ) with the doctor-blade technique.…”

“…21 When the oxygen bridging between the pyrazole-3-carboxylic acid and the Pc ring was removed, the power conversion efficiency was enhanced by up to 2.52% due to the electron injection from Pc to the semiconductor being facilitated. 22 To enhance the performance of DSSC-bearing MPcs, we recently reported a series of MPcs bearing different metal cations, anchoring and spacer groups 23,24 and we reached a maximum efficiency of 3.97% in power conversion with DSSC-bearing TiOPc peripherally substituted with tetra-4-carboxyethylenephenoxy. 25 As a continuity of our studies, we aim to increase the performance of DSSCs with new ZnPcs decorated with different anchoring and spacer groups to increase the performance we have achieved so far.…”

Peripherally, non-peripherally and axially pyrazoline-fused phthalocyanines: synthesis, aggregation behaviour, fluorescence, singlet oxygen generation, and photodegradation studies

“…[9][10][11][12][13][14][15][16] In addition, these compounds are used in many modern application areas, such as electrochemistry, photocatalysis, anticancer drugs, and solar cells. [17][18][19][20] The nature of the metal ion in the center of the phthalocyanine ring, the substituents attached to the ring, and the binding positions of the substituents significantly affect the photophysical and photochemical properties of the compounds (Fig. 1).…”

Clean printing of cotton fabrics using novel environmental‐friendly phthalocyanine‐monoazo reactive dyes

“…However, these researches are mostly focused on the combinations of anthraquinone and azo chromophores. Compared with anthraquinone group, metallophthalocyanine group has been widely discovered as pre‐dyestuff of reactive dye in textile field due to its larger molar extinction coefficient, excellent photo‐stability, bright color, and superior photochemical property 35,36 . For example, Kim et al 37 designed a cationic copper(II) phthalocyanine, and discussed its coloration on acrylic fabrics.…”

Sevim et al 38 reported several metallo-phthalocyanine dyes (M = Ni(II), Zn(II), Cu(II), Co(II)) carrying acid substituents, and the dyes were fixed on the cationic fabric with dyeing uptake of 71%-81%.…”
