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.
