Paper Abstract

We report our continuing investigations of the cumulenes, a novel class of compounds proposed for use as the active second- and third-order nonlinear optical component materials for electro-optic and all-optical devices. Unlike conjugated organic nonlinear optical molecules based on alternating multiple and single bonds, these molecules contain a contiguous, or `cumulated' system of double bonds, leading to a highly rigid one-dimensional backbone of polarizable (pi) -electrons. A series of symmetrically- and asymmetrically-substituted tetraphenyl cumulenes has been synthesized and characterized. Direct-current electric field- induced second harmonic generation experiments show significant second-order nonlinear susceptibilities in a series of polar cumulenes. These experiments have been performed at 1.9 micrometers to avoid dispersion effects. Thermogravimetric analysis indicates survival of a butatriene to 300 degree(s)C.
