Photochromism: Molecules and Systems Heinz Durr, Henri Bouas-Laurent
Publisher: Elsevier Science

In liquid crystalline systems, the molecules behave in collective fashions (cooperative manners), so the photoalignment becomes more and more effective. However, there have been, up to now, no attempts to align the larger mesoscale structures of MPS of block copolymers driven by the photoinduced alignment of photochromic molecules. It is important for students to understand that chemical reactions can take place without the addition of other chemicals or elements to the system, which in directly observable in this isomerization. Photochromic molecules can be loosely divided into two types: those that returnto their initial state at a rate dependent on the ambient temperature ("thermally reversible" photochromic materials), and those which are thermally stable, . Two are pale yellow crystals that are not fluorescent at room temperature and exhibit photochromism (molecule 1 and 4), while the other two (molecule 2 and 3) are not photochromic , but exhibit fluorescence in the solid state.

Nevertheless, up to now, coupled molecular photochromic entities are limited by a series of hurdles (problem of reversibility, parasite reactions, lack of emergent properties…).
