Design, self-assembly, and photophysical properties of pentameric metallomacrocycles: [M5(N-hexyl[1,2-bis (2,2:6,2"-terpyridin-4-yl)]carbazole)5][M = Fe(II), Ru(II), and Zn(II)]

A novel family of metallopentacycles was constructed by the facile self-assembly of a bis(terpyridine)–carbazole monomer utilizing terpyridine–metal(II)–terpyridine connectivity; its photophysical properties were investigated.
