Abstract

A novel CuI2N6 chromophore has been isolated with 2,2'-bis[(4R)-phenyl]-1,3-oxazoline (L) in the optically pure triple-stranded helicate [Cu2L3](ClO4)2, which displays photoluminescence in methanol at room temperature (emission maximum λem = 385 nm; quantum yield Φ = 1.6 x 10-4; lifetime τ ≈ 2 ns) as well as at 77 K (λem = 430 nm; τ = 0.89 ± 0.13 s).
