Co-crystallization of substituted (H, F, CN, CF3) polyfluorinated arylamines with 18-crown-6 to form π-stacked H-bonded 1D assemblies can both produce and quench solid-state fluorescence.
Two novel AIE-active donor–acceptor organoboron complexes with a carbazole donor unit are developed and their morphology-dependent solid-state fluorescence properties are established.
Seven μ-Oacylhydrazone-bridged Ln3 clusters were synthesized. Cluster 3 displayed magnetic refrigeration properties, whereas cluster 5 showed slow magnetic relaxation. The solid-state fluorescence properties of 2, 4 and 5 were also studied.
