2,7,12,17-Tetra(2,5-thienylene)-substituted porphycenes
Kuzuhara, Daiki,Nakaoka, Haruka,Matsuo, Kyohei,Aratani, Naoki,Yamada, Hiroko
, p. 898 - 907 (2019)
We report syntheses of thiophene and dithiophene-substituted porphycenes (ThPc and DThPc) at 2,7,12,17-positions by McMurry coupling. The crystal structure of ThPc revealed that the porphycene plane shows a highly planar structure, and the dihedral angles between the porphycene core and thiophene are relatively small at 21deg and 18deg. ThPc and DThPc exhibit red-shifted and broadened absorption because of the extension of I conjugations through porphycene to the substituted thiophenes. We found that introduction of thiophene units onto porphycene results in decreasing the HOMO-LUMO differences effectively.
