Next Generation of Photoalignment

The fascinating ability to control molecular
orientation by light has drawn many attentions for
the last decade. In fact it enables large
opportunities to design materials with controllable
properties and use it to create new electro-optical
devices. This book dwells upon the physical mechanism
leading to photo orientation of molecules, also known
as photoalignment. The problem is addressed as
statistical average of the sequence of independent
events on photo-dissociation and self-association of
reversible intermolecular bonds (e.g. H-bonds), which
enable and disable self-consistency condition for
molecular relaxation in long range Mean field
potential. Feasible theoretical description is
verified in original experiments on photo orientation
of molecules of dyes and dye mixtures. Novel
considerations shed light on the functional role of
specific radical groups and give hint of new chemical
structures of photoalignment materials for optically
rewritable electronic paper and photonics devices
described here. The book should be useful to
professionals in Condensed matter theory and
chemistry, or anyone else who may be considering
utilizing photoalignment for molecular orientation.
