Two polymorphs of a benzoxadiazole derivative were examined to determine the interactions leading formation two distinct crystalline forms. Hirshfeld surface analysis was used establish and contrast in samples. Fingerprints derived from distinguish lead discovering different crystals. π interactions, specifically, π-hole with nitro moiety, found play an important role crystal structure. Further...

A novel class of bolapolyphile (BP) molecules are shown to integrate into phospholipid bilayers and self-assemble into unique sixfold symmetric domains of snowflake-like dendritic shapes. The BPs comprise three philicities: a lipophilic, rigid, π-π stacking core; two flexible lipophilic side chains; and two hydrophilic, hydrogen-bonding head groups. Confocal microscopy, differential scanning ca...
