Enhanced Circularly Polarized Luminescence by a Homochiral Guest-Host Interaction in Gyroidal MOFs, [Ru(bpy)₃] [M₂(ox)₃] (bpy = 2,2'-Bipyridyl, ox = Oxalate, M = Zn, Mn).

ABSTRACT: We report the circularly polarized luminescence (CPL) for [Ru(bpy)₃]I₂ (1) and [Ru(bpy)₃][M₂(ox)₃] (M = Zn (2), Mn (3)). Whereas compound 1 is a simple salt of [Ru(bpy)₃]²⁺, 2 and 3 are MOFs in which the chiral [Ru(bpy)₃]²⁺ ions are encapsulated in a homochiral gyroidal skeleton of [M₂(ox)₃]^2-. Whereas the solution of 1 exhibited weak CPL with a luminescence dissymmetry factor of |g_lum| ∼ 10^-4, the CPL was significantly enhanced in solid-state 1-3 with |g_lum| = 2 × 10^-2 for 1, 4 × 10^-2 for 2, and 1 × 10^-1
