W ell-defined, low molecular weight amorphous organic materials based on polyaromatic compounds exhibit
interesting optical, electronic, and magnetic properties; whereas they can also serve as the basis for developing
lithographic materials. Thus, they have been receiving attention for the development of organic devices in the nanoscale
with substantially enhanced performance and new functions. Solution processability of such materials is highly desirable,
since techniques, such as spin-coating, lower significantly the cost for the fabrication of the devices. Herein, a design
strategy and synthesis of solution-processable small molecules, with well-defined monomolecular structures based on
anthracene, is presented. Anthracene moieties are combined with other poly-functionalized planar and tetrahedral cores,
providing control of physicochemical properties, such as solubility, thermal stability, and Tg. Selected members of this
class, provided amorphous homogeneous films which were stable at temperatures up to 150°C. These molecules have
been, also, evaluated as main components in the active layer of OLEDs, providing very promising results. Self-patterning
was also allowed by incorporation of suitable acid-sensitive functional groups and a photoacid generator. These results
demonstrate the potential of these materials to be used in the fabrication of patterned structures for OLEDs. A flexible,
efficient and cheap methodology, suitable for the preparation of these anthracene-based molecules in large scale is also
described, using representative examples.
