In this study, we have reported for the first time a complete experimental investigation on the compound Neutral Red and the new monobrominated derivative in different media as a function of the concentration. These compounds belong to the quinone-imine class of dyes and have good potential to be applied as photosensitizers in Photodynamic Therapy.Although the aggregation of Neutral Red has been reported by several authors, this has not been thoroughly evaluated due to spectral changes occurring depending on the solvent and concentration of dye.

“…The overview is limited to solution‐processed BHJ OSCs with a porphyrinoid material in the active layer blend (or interfacial layer). Related device structures in which porphyrin‐type materials have been applied, such as bilayer (planar heterojunction), p‐i‐n BHJ, interdigitated BHJ, dye‐sensitized BHJ, hybrid, and photoelectrochemical devices are not covered. We discuss both the structural aspects of the porphyrinoid materials (including basics of the synthetic procedures applied) and their optoelectronic properties and solar cell characteristics.…”

Organic photovoltaics (OPV) represent a thin‐film PV technology that offers attractive prospects for low‐cost and aesthetically appealing (colored, flexible, uniform, semitransparent) solar cells that are printable on large surfaces. In bulk heterojunction (BHJ) OPV devices, organic electron donor and acceptor molecules are intimately mixed within the photoactive layer. Since 2005, the power conversion efficiency of said devices has increased substantially due to insights in the underlying physical processes, device optimization, and chemical engineering of a vast number of novel light‐harvesting organic materials, either small molecules or conjugated polymers. As Nature itself has developed porphyrin chromophores for solar light to energy conversion, it seems reasonable to pursue artificial systems based on the same types of molecules. Porphyrins and their analogues have already been successfully implemented in certain device types, notably in dye‐sensitized solar cells, but they have remained largely unexplored in BHJ organic solar cells. Very recent successes do show, however, the strong (latent) prospects of porphyrinoid semiconductors as light‐harvesting and charge transporting materials in such devices. Here, an overview on the state‐of‐the‐art of porphyrin‐based solution‐processed BHJ OPV is provided and insights are given into the pathways to follow and hurdles to overcome toward further improvements of porphyrinic materials and devices.

“…The technological applications of porphyrins and their derivatives include: γ -ray and gas sensors [1,2], solar cells [3], photochromic recording media [4], photonic devices [5], catalysis [6] and photo-electrochemical cells [7]. Porphyrins also show relatively high efficiencies in the dye-sensitized solar cells (DSSCs) [8,9].…”
