|Title:||The development of self-assembled LCD alignment layers|
|Date:||Thu Dec 7, 2006|
|Start:||16.00 (Doors open and coffee available at 15.30)|
From simple pocket calculators, to mobile telephones and LCD-TV, over the past few decades devices based on liquid crystal display technology have proliferated into just about all conceivable aspects of everyday life. Although used in cutting-edge technology, it is surprising that a vital part in the construction of such displays, namely the alignment layer, relies essentially on a mechanical rubbing process, invented almost 100 years ago.
In this lecture I will discuss efforts to develop alignment layers (also called command layers) by other processes than rubbing, namely self-assembly of molecular and macromolecular components. Two examples will be presented: (i) tunable command layers formed by stepwise assembling siloxane oligomers and phthalocyanine dyes on ITO surfaces and (ii) command layers formed by self-assembly of porphyrin trimers. The potential use of these layers in sensor devices will be discussed.
