Abstract
The use of a multi-functional, chromophore containing, polymerizable compound for producing an optical element having non-linear optical properties (an NLO element) wherein the multi-functional chromophore is a compound capable of being polymerized into a cross-linked network and of being poled under the influence of an electric field whilst being polymerized into the cross-linked network, the compound having the generalized formula EQU (D) (C) (A) (F) D, C, A and F representing covalently linked moieties where C represents at least one conjugated system of .pi.-bonds, PA0 A and D represent at least one respectively .pi.-electron acceptor and .pi.-electron donor groups linked at opposite ends of the conjugated system, and are preferably conjugated with the conjugated system of .pi.-bonds (C) and where more than one moiety A, C or D is present they may be the same or different, PA0 F represents at least two polymerizable functional groups, which may be the same or different, attached to the .pi.-conjugated system C or the groups A and D via substituent groups R.sub.1, and R.sub.2, where R.sub.1 and R.sub.2 are selected from alkyl, cycloalkyl, aryl heteroalkyl, alkenyl, cycloalkenyl,…
