Anthracene-based molecular glasses: Design, synthesis and applications in nanolithography and
organic electronics overview and perspectives

A
nthracene derivatives constitute a promising class of small molecules with many potential applications, in the areas
of organic electronics and nanolithography. Indeed, anthracene exhibits attractive properties for incorporation in
films used in electronic devices (electronic conductivity, high charge mobility, appropriate ionization potential) and
nanolithography applications (high etch resistance). Nevertheless, its high crystallization and sublimation tendencies pose
severe challenges in the use of robust solution processes and in the formation of high quality films. Thus, the development
of optimized anthracene-based compounds with tunable properties depending on the application is necessary. Towards
this direction, developed synthetic routes lead, mainly, to symmetric structures using expensive organometallic reactions.
Herein, a design strategy for the synthesis of anthracene-based molecular glasses (MGs), suitable for applications in
nanolithography and with perspectives for application in organic photonic devices is presented. Film-forming properties
were tuned, by controlling molecular architecture, structure flexibility and incorporation of tetrahedral and planar cores.
Cheap, efficient and scalable methods, based mainly on esterification reactions, were applied, leading to the synthesis
of a "library" of diverse anthracene-based structures from common intermediates. Many of these molecules were highly
soluble, thermally stable and formed amorphous and stable films, introducing a new class of solution-processable
anthracene-based MGs with high etch resistance and suitable for positive-tone chemically amplified systems. Moreover,
in certain cases, film patterning in EUV, reached dimensions below 30 nm. Recently, selected compounds have been
tested as active layers in OLED structures affording very promising results. Additional perspectives of this research will
be discussed.
