Photoluminescence Properties of Discrete Conjugated Wires Wrapped within Dendrimeric Envelopes: “Dendrimer Effects” on π‐Electronic Conjugation

Third-generation dendrimers have been used to enable the synthesis and isolation of a series of spatially isolated, discrete conjugated wires G3-n (where n is the number of repeating monomer units, see schematic representation), including 147-nm long G3-64, which contains 192 aromatic rings and 256 triple bonds in the backbone. Photochemical studies show there is enhanced π-electronic conjugation in these systems.
