Synthesis and characterization of porphyrins bearing four redox-active phenylenediamine pendant groups as a dimensionally oriented π-conjugated system
摘要:
Porphyrins bearing phenylenediamine pendant groups were synthesized to afford dimensionally oriented pi-conjugated systems. The structural and electronic characteristics depend on the alphaalphaalphaalpha and alphabetaalphabeta atropisomers. In the fluorescence emission spectra, the emission from the porphyrin moiety was almost completely quenched. Zinc complexation of the alphaalphaalphaalpha isomer with zinc(II) acetate led to the corresponding zinc complex. (C) 2002 Elsevier Science Ltd. All rights reserved.
