“…Natural chlorins such as chlorophylls, which play a vital role in photosynthetic processes, are considered promising PS. However, the use of these naturally reduced porphyrins in PDT requires laborious extraction and modification of natural derivatives or total synthesis approaches, which are both a tremendous disadvantage [ 29 , 30 ]. To overcome this issue, efficient synthetic approaches to prepare chlorin-type macrocycles and other meso -tetraarylporphyrin reduced derivatives (e.g., (iso)bacteriochlorins) were developed, namely, those involving porphyrin precursors in cycloaddition reactions, such as Diels–Alder reactions and 1,3-dipolar cycloadditions [ 31 ].…”

Skin cancer is one of the cancers that registers the highest number of new cases annually. Among all forms of skin cancer, melanoma is the most invasive and deadliest. The resistance of this form of cancer to conventional treatments has led to the employment of alternative/complementary therapeutic approaches. Photodynamic therapy (PDT) appears to be a promising alternative to overcome the resistance of melanoma to conventional therapies. PDT is a non-invasive therapeutic procedure in which highly reactive oxygen species (ROS) are generated upon excitation of a photosensitizer (PS) when subjected to visible light of an adequate wavelength, resulting in the death of cancer cells. In this work, inspired by the efficacy of tetrapyrrolic macrocycles to act as PS against tumor cells, we report the photophysical characterization and biological assays of isobacteriochlorins and their corresponding chlorins and porphyrins against melanoma cancer cells through a photodynamic process. The non-tumoral L929 fibroblast murine cell line was used as the control. The results show that the choice of adequate tetrapyrrolic macrocycle-based PS can be modulated to improve the performance of PDT.

“…According to the molecular structure of chlorophyll, four nitrogen atoms coordinate with the central Mg atoms, acting as electron donors [ 43 ]. The presence of a high chlorophyll content not only promotes the conversion of photons into charge carriers but also intensifies the positive triboelectric charges owing to the electron donor ability of the chlorophyll molecule.…”

Green and sustainable power sources for next-generation electronics are being developed. A cellulose paper-based triboelectric nanogenerator (TENG) was fabricated to harness mechanical energy and convert it into electricity. This work proposes a novel approach to modify cellulose paper with natural dyes, including chlorophyll from spinach, anthocyanin from red cabbage, and curcumin from turmeric, to enhance the power output of a TENG. All the natural dyes are found to effectively improve the energy conversion performance of a cellulose paper-based TENG due to their photogenerated charges. The highest power density of 3.3 W/m2 is achieved from the cellulose paper-based TENG modified with chlorophyll, which is higher than those modified with anthocyanin and curcumin, respectively. The superior performance is attributed not only to the photosensitizer properties but also the molecular structure of the dye that promotes the electron-donating properties of cellulose.

“…1 The characteristics of intermolecular interactions have a critical impact on the electrophysical characteristics of organic semiconductor materials 2 including natural porphyrinoids. 3 Intermolecular non-covalent interactions are relatively weak and can be changed with an external stimulus, without the destruction of the material. In particular, biological systems in living nature make extensive use of molecular self-assembly via non-covalent interactions to tune their functionality under external impact.…”
