Star-shaped oligofluorene truxenes are very promising materials and have demonstrated excellent properties as the gain medium in organic semiconductor lasers (OSLs).1-10 Alkyl chains in oligofluorene truxenes act as solubilizing groups as well as spacers to prevent intermolecular π-π stacking that leads to quenching of the light emission. A new series of star-shaped systems analogous to hexyl oligofluorene truxenes11 with alkyl chains of different lengths (butyl chains and octyl chains) was synthesized. The objective of this study was to investigate the effect of alkyl chain length on the film-forming properties of oligofluorene-truxene materials and, as a result, on their optoelectronic properties for applications as the gain medium in OSLs.
