Abstract—Herein, the author synthesized a donor-acceptor type of photochromic dimethyl 2,3-bis(arylethynyl)fumarate, (
E)-2, where ferrocene and 4-nitrobenzene were employed as donor and acceptor arenes, respectively. Compared to parent dimethyl 2,3-bis(ferrocenylethynyl)fumarate, (
E)-2 enjoyed more profound donor-acceptor interaction, leading to a red-shifted intramolecular charge transfer band. (
E)-2 underwent visible-light photochromism upon excitation with the intramolecular charge transfer band.
Index Terms—Photochromism, ferrocene, donor-acceptor interaction.
