Intense red emissive organic crystals with elastic bending ability and optical waveguiding behaviour.

Orange (Cry-1O) and red (Cry-1R) emissive crystals with mechanical brittleness and elasticity, respectively, were obtained by modifying the crystallization conditions based on a green emissive molecule. The light transducing capability of Cry-1R in both the straight and bent states indicates the potential application of Cry-1R as an active optical waveguiding medium. [ABSTRACT FROM AUTHOR]
