Floppy organic LEDs
In Telluride last week Peter Rossky gave a nice talk about work in his group on electronic properties and excited state dynamics of conjugated molecules such as PPV used in LEDs and Organic Photovoltaics. One thing he emphasized was that cartoon pictures of these molecules as rigid and planar are not accurate. At room temperature molecules such a PPV can flop around substantially, as described in this paper.
