A. Klys et al., Planar chiral derivatives of 1,1 '-diphosphaferrocene with potential application in nonlinear optics, INORG CH C, 4(4), 2001, pp. 205-207
Planar chiral "push-pull" derivatives of I,1 ' -diphosphaferrocene were obt
ained in the Knoevenagel reaction starting from racemic or optically resolv
ed 2-formyl-3,3 ' ,4,4 ' -tetramethyl-1,1 ' -diphosphaferrocene. Their seco
nd-order non-linear optical (NLO) properties were studied by powder tests a
nd the EFISHG technique at 1.907 mum. (C) 2001 Elsevier Science B.V. All ri
