Effects of molecular design on thermal, optical, molecular packing properties, and ΔG characteristics. (A) DSC trace (2nd cycle) of DPP derivatives (scan rate 10 °C·min –1). (B) Normalized PL of shear-triggered (DPP8 and DPP12) and thermally driven (DPP4 and DPP16) crystals. (C) Powder XRD traces. DPP8, -12, and -16 have similar lamellar packing patterns in contrast to the drastically different diffraction pattern of DPP4. (D) ΔG between the crystalline solid and supercooled liquid phases of DPP derivatives (from the Hoffman equation, at 26 °C).
