6.60- diheptyl-bipyridyl-diol

Diheptyl-bipyridyl-diol (DH-BP(OH)2) can serve as an example, the structure of which is shown in Figure 41.2 [45]. This compound is proposed as a model luminescent molecule exhibiting the above-described property of... 

A number of recent papers report a dramatic increase in luminescence of diheptyl-bipyridyl-diol [45], organic dyes, and other species in the presence of silver [33,56-59], gold [60], and copper [61] NPs (plasmons) compared with the luminescence of the same complex without plasmons. The absorption coefficient of the NPs is six orders of magnitude higher than that of organic molecules. These papers provide a promising approach to increase the efficiency of LSCs.
