Crystallochromy
WebJan 17, 2012 · Whilst searching the literature, we stumbled upon the term “crystallochromy”, which was defined as the dependence of solid‐state color on crystal packing. WebMay 17, 2010 · The isopropyl derivative exhibited the highest fluorescence quantum yield in the solid state of 0.90 in the series of alkylated tetracenes. X-ray analysis revealed that there were significant structural differences in alkyl conformation and crystal packing. The crystallochromy effects are derived from the unique crystal-packing patterns.
