Objective
The use of fullerenes in products of substantial economic and societal impact, such as sensory or photovoltaic devices, is impeded by the lack of methods allowing their incorporation into highly organised molecular materials. This project will focus on breaking this technological barrier by building supra-molecular hybrid materials combining fullerenes with conjugated oligomers or polymers. These materials will rely on the use of complementary molecular recognition motifs to induce the self-assembly of organised, highly functional architectures. We will construct and evaluate the performance of novel sensory and photovoltaic devices based on these new materials.
OBJECTIVES
The goal of the project is to construct molecular electronic components by self-assembly of fullerene nano-objects. We will investigate the electronic properties of these new components; placing particular emphasis on charge injection and photo-induced electron transfer processes. These results will be used to design and demonstrate the utility of novel sensory and photovoltaic devices.
DESCRIPTION OF WORK
During this project, we will:
1) design and construct novel fullerene architectures capable of self-organisation into functional molecular electronic components;
2) demonstrate the use of these new devices in the fabrication of sensors and light-to-energy conversion products. To begin, we will use a fullerene derivative fused to a barbiturate unit to assemble hydrogen-bonded ribbon architectures in the presence of complementary melamine-containing conjugated polymers. These structures are apt to function as self-assembled p-n junctions because of the special arrangement of the molecules within the linear architecture of the ribbon, and it is expected that such devices will exhibit superior electronic performance due to their highly organised molecular structure. We will use a modified AFM set-up available in the consortium to simultaneously gather structural and electronic information, thereby evaluating the impact of molecular organisation on the efficiency of the device. The self-organised architectures described in this proposal are hybrid fullerene-conjugated oligomer materials selected to rapidly lead to the construction of functional devices.
They include the preparation of:
i) self-assembled p-n junctions;
ii) multi-layer devices. In all cases, the interplay of molecular organisation and electronic properties will be evaluated and used as a basis to engineer new functional architectures.
