Inherently chiral helicene-substituted thioalkyl porphyrazine complexes: synthesis and electronic and chiroptical properties

Abstract

The chiral Ni(II) and Pd(II) complexes of [6]helicene thioethyl porphyrazine have been synthesized and their spectroscopic, electrochemical, and chiroptical properties have been investigated by experimental and computational analyses. In these...

Porphyrin- and Bodipy-helicene conjugates: syntheses, separation of enantiomers and chiroptical properties

“…1). Several examples of helical porphyrinoids [15][16][17][18][19][20][21][22][23][24][25][26][27] and Bodipy-helicenes conjugates were described earlier in the literature. [28][29][30][31][32][33][34][35][36][37][38] Some of us have shown recently that a fused porphyrin-helicene conjugate presented interesting absorbance properties covering the full visible spectrum.…”
