Molecular structure and optical nonlinearity of 1,8-bis(ferrocenyl)-3-t- butyl-oct-3-ene-1,5,7-triyne

Abstract

Interaction of 1,8-bis(ferrocenyl)-octatetrayne 1 with one equiv. of t-butyl lithium followed by treatment with water gave 1,8-bis(ferrocenyl)-3-t- butyl-oct-3-ene-1,5,7-triyne 2. The solid-state structure of 2, containing a bent carbon chain between two ferrocenes, has been determined. The nonlinear optical properties of 2 were also investigated.
