Design, self-assembly, and photophysical properties of pentameric metallomacrocycles: [M-5(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.
