Efficient Electronic Communication in 4,9-Bis(ferrocenylethynyl)dimethyldihydropyrene
We have prepared the dimethyldihydropyrene (DRIP) derivative 2, which possesses two ferrocenyl groups at the 4- and 9-positions through ethynylene linkers. 2 shows intense electronic communication between the two ferrocenyl groups, which is promoted by the highly developed pi orbital of the diethynyl DHP moiety.
