Professor Franco Cacialli of the University
College London has become a fellow of the American Physical Society upon
the recommendation of the Division of Materials Physics.

His work has contributed to organic semiconductors and related applications,
and to the fabrication of conjugated polymers nanostructures via scanning near-field
optical lithography (Appl. Phys. Lett. 82, 526,2003), and more recently scanning
thermal lithography (Nature Nanotechnology 4, 664, 2009). Professor Franco Cacialli
also proposed a new method to investigate probe-induced sample heating in apertured
near-field experiments (Appl. Phys. Lett. 86, 11102 (2005)), exploiting organic
semiconductors thermochromism. His work on polymer LEDs ranged from the first
demonstration of extended device lifetimes (~1000 hours, Synth. Met. 67, 157,
1994), to a comprehensive study of charge injection issues, and optimisation
of injection barriers (e.g. J. Appl. Phys. 84, 6859, 1998; Appl. Phys. Lett.
79, 174, 2001), including the direct measurement of the work function increase
upon incorporation of PEDOT:PSS hole-injection layers in finished devices (Appl.
Phys. Lett. 75, 1679, 1999).
Professor Franco Cacialli has also developed a keen interest for supramolecularly
engineered materials in general, and threaded molecular wires (TMWs) in particular,
thanks to collaboration with the group of HL Anderson at Oxford. In 2002 they
have reported the first optical and electroluminescence characterisation of
such wires, and since then demonstrated the dramatic effects that threading
of conjugated polymers into insulating cyclodextrin rings (to form conjugated
polyrotaxanes) has on the control of intermolecular excitations (F. Cacialli
et al. Nature materials, 1, 160, 2002).
