Abstract

A crosslinkable side chain NLO-polymer of the bis-azobenzene type and an AB-type main chain NLO-polymer of the sulphonyl-tolane type have been synthesized and characterized with respect to their curing and electric poling properties. NLO-susceptibilities d₃₃ of 11 pm/V and 7.5 pm/V, respectively, have been measured after initial relaxation and proved to be highly stable. During poling, transient SH-signal and square of poling current showed similar temporal behavior. Thus transient poling current can be considered to be a useful probe to monitor and to control the poling process. Direct current electrical conductivity was found to be strongly temperature dependent for both materials.
