“…In that respect, they allow to produce a variety of materials for many applications, such as metal ion chemosensing [7], electroluminescence [55], liquid crystals [56], or photoconductivity [57]. Conjugated polypyridine ligands are also being exploited as building-blocks for the constructions of nanostructures such as macrocycles [58] [59], hyperbranched structures [60], polytopic modules for nanoengineering [61], or self-assembled chromogenic ion sensors [62]. Moreover, this account emphasizes the behavior in the singlet excited-state but conjugated polypyridine ligands also allow to investigate triplet state properties.…”

“…Boradiazaindacene (BODIPY)-appended (82)(83)(84)(85)(86) [35] [72] and pyrenyl-appended (87) tpy derivatives were also reported [73], the fluorescence properties of which were quite similar to those of the bpy derivatives.…”

“…Another type of metal-binding macrocycle, twistophane, incorporating 5,5'-connected bpy (113) [85] and 6,6'-connected bpy (114 and 115) [86] has been synthesized. Molecular mechanics calculations of 113-115 showed helically twisted chiral conformations.…”

Oligopyridines connected through the 2-and 6-positions have long been the subject of continuing interest because of their high ability to interact with metal ions and/or other molecules, and their transition-metal complexes have been intensely studied for decades because of their characteristic photophysical properties. However, relatively few have been known in regard to the photophysical and photo-functional properties of oligopyridine derivatives. From the late 1990s, fluorescent oligopyridines have been of considerable interest as tunable fluorophores by intermolecular interaction, and the design and synthesis of novel oligopyridine derivatives and their application to fluorescent sensors has increasingly been studied. In this article, we will review recent developments of fluorescent oligopyridines and their photo-functionality.

“…Baxter has also prepared, via an analogous synthetic protocol, the twistophane macrocycle 87, where the 2,2 0 -bipyridine moieties are incorporated into the macrocyclic backbone at the 6,6 0 -position [37]. The selective ion sensory properties of this macrocycle were also established through UV-vis and fluorescence measurements.…”
