Abstract
Circular polarized luminescence (CPL) materials attract great attentions owing to their extensive applications in 3D optical displays and encrypted transmission. Inspired by the strategies adopted in CPL materials of lead(II) perovskites, we have successfully attained CPL-active hybrids D- and L-( tert-butyl prolinate )MnCl 3 by assembling chiral D/L tert-butyl prolinate with manganese(II) chloride. As demonstrated by single crystal X-ray diffraction, the as-formed hybrids consist of one-dimensional (1D) chains of face-sharing MnCl 6 octahedra, surrounded by prolinate cations. The 1D Mn(II) hybrids display strong red emission peaked at 646 nm with PLQY of 67.1 % for D-type and 57.2% for L-type, which are among the highest rank of PLQY in 1D Mn(II) hybrids. Interestingly, the 1D Mn(II) hybrids exhibit prominent circular dichroism (CD) signals and remarkable CPL activity with the dissymmetry factor g of 6.1´10 -3 and -6.3´10 -3 for D- and L-( tert-butyl prolinate )MnCl 3 , respectively. The obtained g represents the highest value for non-lead organic-inorganic hybrids.
