Planar chiral derivatives of 1,1 ′-diphosphaferrocene with potential application in nonlinear optics

Planar chiral “push–pull” derivatives of 1,1 ′-diphosphaferrocene were obtained in the Knoevenagel reaction starting from racemic or optically resolved 2-formyl-3,3 ′,4,4 ′-tetramethyl-1,1 ′-diphosphaferrocene. Their second-order non-linear optical (NLO) properties were studied by powder tests and t...

Description
Summary:Planar chiral “push–pull” derivatives of 1,1 ′-diphosphaferrocene were obtained in the Knoevenagel reaction starting from racemic or optically resolved 2-formyl-3,3 ′,4,4 ′-tetramethyl-1,1 ′-diphosphaferrocene. Their second-order non-linear optical (NLO) properties were studied by powder tests and the EFISHG technique at 1.907 μm.
