A porphyrin-triazatruxene dyad for ratiometric two-photon fluorescent sensing of intracellular viscosity

“…The TAT-ZnPor dyad was formulated by a typical electron-rich triazatruxene ( TAT ) moiety 25 and an electron-deficient zinc porphyrin moiety ( ZnPor ) 26 via an ethynyl linkage, which satisfies a D-π-A configuration for high two-photon absorption (TPA) coefficients. Furthermore, the rotation about the ethynyl bridge can be modulated by changing the viscosity of media, therefore viscosity responsive fluorescent performance can be expected according to the TICT mechanism.…”

Fluorinated Antimony(V) Tetraarylporphyrins as High-Valent Electron Acceptors with Unparalleled Reduction Potentials

“…Main-group porphyrins are one of the most versatile and fascinating molecules in the porphyrin family as they are highly photoactive, redox-rich, and possess flexible structural properties. − Notably, these properties can be tuned easily by incorporating a variety of main-group elements in the porphyrin cavity . Additionally, the photophysical and redox properties can be adjusted by functionalizing the porphyrin peripherals. − Axial bonding is another active mode of functionalizing that is distinctive of the main-group porphyrins. ,,, These adaptable properties make them potential candidates for a range of applications which include artificial photosynthesis, ,,− dye-sensitized solar cells, , molecular catalysis, ,, molecular electronics and photonics, − photodynamic therapy, − etc.…”

Computational study of ground‐state properties of μ2‐bridged group 14 porphyrinic sandwich complexes

“…Porphyrins have first been synthesized in the 1920s 21,22 and have become a highly important topic of research since then 23–26 . In this context, silicon as a central metal is also of particular relevance 27–30 . Some of the most common industrial and pharmaceutical applications cover dye‐sensitized solar cells (DSSC), 31,32 artificial photosynthesis, 33,33 photochromic diodes or switches, 34,35 spin switches, 36,37 permanently polarized materials, 38,39 liquid crystals, 40,41 (enantio)‐selective catalysis for oxidation processes, 42,43 gas separation and CO 2 capture, 44,45 photosensitizers, 46,47 or artificial blood 48,49 .…”
