|a Certain synthetic analogues of the green fluorescent protein (GFP) chromophore are almost nonfluorescent in dilute solutions but are strongly light-emissive in the solid state, thus exhibiting aggregation-induced emission (AIE) behavior. In the present work, two such hydrophobic derivatives of the GFP chromophore known to be fluorescent in the crystalline state (p-hexyloxy- and p-dodecyloxybenzylideneimidazolinone) were used to prepare aqueous suspensions of particles via a mild solvent-exchange reprecipitation (RP) method. This evolution was monitored at various experimental conditions by UV-vis absorption and fluorescence spectroscopy, fluorescence microscopy, as well as electron transmission and scanning microscopy. Both compounds spontaneously produced platelet-like microcrystals, the size and shape of which were influenced by the experimental conditions. The dodecyl derivative also led to the concomitant formation of nanofibers, a tendency reinforced by addition of poly(acrylic acid) to the RP medium. The photoluminescence properties of the solids produced by RP were compared to pristine microcrystalline powders obtained by crystallization in an organic solvent. Significant differences in the emission properties were found and are discussed. This study illustrates the fact that AIE fluorescence is strongly dependent on the nature of the particles and hence on the preparation methods. Being aware of these variations is important for the preparation and subsequent use of AIE-active compounds as fluorescent materials
