Leading national thinking on politics, government & public policy through Open Access research

Strathprints makes available scholarly Open Access content by researchers in the School of Government & Public Policy, based within the Faculty of Humanities & Social Sciences.

Research here is 1st in Scotland for research intensity and spans a wide range of domains. The Department of Politics demonstrates expertise in understanding parties, elections and public opinion, with additional emphases on political economy, institutions and international relations. This international angle is reflected in the European Policies Research Centre (EPRC) which conducts comparative research on public policy. Meanwhile, the Centre for Energy Policy provides independent expertise on energy, working across multidisciplinary groups to shape policy for a low carbon economy.

Abstract

We report the controlled patterning of nano-sized oligofluorene truxenes onto silicon dioxide by dip-pen nanolithography (DPN) using a UV-curable pre-polymer as a carrier fluid. In this technique, a sharp atomic force microscope (AFM) cantilever tip is used to transfer the liquid ink onto a surface using piezo-controlled movements and excellent spatial registry. The photo-curable carrier fluid is then exposed to UV-light to produce a cross-linked, host matrix while retaining the photoluminescent properties of the truxenes and providing protection against photo-oxidation. The chemical composition of the composite structures deposited by DPN was characterised by Raman microspectroscopy and microphotoluminescence to demonstrate successful incorporation of the photoluminescent truxenes in the polymer matrix.
