The Relation between Packing Effects and Solid State Fluorescence of Dyes.
In: Journal für Praktische Chemie, Vol. 333, No. 5: pp. 733-748
The solid state fluorescence of diketopyrrolopyrrole dyes and perylene-3,4:9,10- tetracarboxylic bisimides with alkyl substituents are investigated and compared with noncovalent interactions. The latter are estimated by crystal structure analysis, heats and entropies of fusion and solubilities in organic solvents. Applications of the dyes are discussed.
