“…Dye-sensitized solar cells (DSSCs) are an effective alternative for delivering clean energy from the sun compared to traditional power cells [1][2][3][4]. Numerous efforts are currently being directed toward the development of optimized light harvesters capable of utilizing the entire range of the solar spectrum, including the infrared portion lost in present silicon-based PV technology.…”

An asymmetrical, push–pull phthalocyanine bearing bulky tert-butylcarbazolyl moieties as electron donor and carboxylic acid as anchoring group was synthetized and tested as a photosensitizer in dye-sensitized solar cells (DSSC). The new photosensitizer was characterized by 1H and 13C NMR, UV–Vis and mass spectrometry. The bulky tert-butylcarbazolyl moieties avoid the aggregation of the phthalocyanine dye. DFT studies indicate that the HOMO is delocalized throughout the -electron system of the substituted phthalocyanine and the LUMO is located on the core of the molecule with a sizable electron density distribution on carboxyl groups. The new dye has been used as a photosensitizer in transparent and opaque dye-sensitized solar cells, which exhibit poor efficiencies related to a low Jsc.

“…As an example, TiO 2 in different forms is included in photovoltaics, well-established devices are TiO 2 -based dye sensitized solar cells (DSSC) [2][3][4]. Good efficiencies of DSSCs have been obtained by the use of transition metal phthalocyanines (TMPcs), including iron phthalocyanine (FePc) as the light harvester [5,6]. Although numerous applications are based on titanium dioxide nanomaterials [7][8][9], well defined single crystalline rutile or anatase TiO 2 surfaces can serve as a model system.…”

FePc and FePcF16 on Rutile TiO2(110) and (100): Influence of the Substrate Preparation on the Interaction Strength

et al. 2019

Interface properties of iron phthalocyanine (FePc) and perfluorinated iron phthalocyanine (FePcF 16 ) on rutile TiO 2 (100) and TiO 2 (110) surfaces were studied using X-ray photoemission spectroscopy (XPS), X-ray absorption spectroscopy (XAS), and low-energy electron diffraction (LEED). It is demonstrated that the interaction strength at the interfaces is considerably affected by the detailed preparation procedure. Weak interactions were observed for all studied interfaces between FePc or FePcF 16 and rutile, as long as the substrate was exposed to oxygen during the annealing steps of the preparation procedure. The absence of oxygen in the last annealing step only had almost no influence on interface properties. In contrast, repeated substrate cleaning cycles performed in the absence of oxygen resulted in a more reactive, defect-rich substrate surface. On such reactive surfaces, stronger interactions were observed, including the cleavage of some C-F bonds of FePcF 16 .

“…Photosensitizers based on phthalocyanines, porphyrins and related systems are interesting nanomaterials with multiple applications in different fields ranging from molecular photovoltaics [124][125][126][127] to nanomedicine. [11,[128][129][130][131] The design of biohybrids materials by linking porphyrinoids and biomolecules allows the enhancement and the appearance of new valuable properties for the use of these complexes in a biological media.…”

The use of photosensitizers (PSs) in photodynamic therapy (PDT) and photodynamic inactivation of microorganisms (PDI), as well in other biomedical techniques as medical imaging, represents a challenge for improving given properties that are desired in a biological media, such as water solubility, lack of aggregation and biocompatibility, among others. This review shows the most recent and important examples of the conjugation of photosensitizers to different biomolecules to achieve this goal. The manuscript is written in an accessible way in order to give a general vision of the recent advances stimulating at the same time the curiosity of the reader.
