Tribology and the Liquid-Crystalline State will be an important addition to the tribology literature and will be especially helpfiil to those in industry or academia who are engaged in an exciting and growing research area-the tribology of liquid crystals.

In a different approach, Bruce and coworkers 210) described the preparation of liquid-crystalline derivatives of a N,C,N-Pt (II) Imninophore (Fig. 18). Interestingly, they foimd that emission in the liquid-crystal phase is characteristic of the monomeric complex, while excimer-like emission normally characterizes nonliquid-crystalline analogues. They showed that the emission of pure films is responsive to both method of preparation and tribological stimulation so that it is possible to switch in a controllable manner between monomer- and excimer-like states.
