Molecular Photonics Laboratory
School of Chemistry
Newcastle upon Tyne
The Molecular Photonics Laboratory is a research organisation concerned with the design, synthesis and photophysical examination of multi-component molecular systems, at both fundamental and applied levels. Our particular interest lies with the detailed investigation of molecular materials for artificial photosynthesis, including the optimisation of molecular arrays suitable as light-harvesting networks. The Laboratory is funded, in part, by EPSRC. Further details can be found at: www.ncl.ac.uk/mpl/
NB A Faraday Discussion devoted to artificial photosynthesis will be held at Edinburgh in early September. See:
Current research is concerned with the design of molecular photonic devices based on a detailed understanding of energy- and electron-transfer processes. This is an extension of earlier work aimed at the development of artificial photosynthetic systems and relies heavily on the use of photophysical studies. On-going collaborations with synthetic chemists (Raymond Ziessel at Strasbourg and Andy Benniston at Newcastle) provide the necessary materials for comprehensive examinations. Our work concerns seeking a better understanding of the fundamental principles of charge transfer in molecular systems and involves both experimental and theoretical studies. International collaborations with colleagues in Europe and the United States continue. All research work is now conducted through the Molecular Photonics Laboratory – a specialised university research centre established in 2002. Modest funding has been obtained to renovate laboratory and office space and to install safety features necessary for pulsed laser spectroscopy. Extant equipment includes a range of steady-state and time-resolved spectrometers for recording photophysical events over time scales ranging from sub-ps to minutes. Ancillary detection facilities permit the detailed examination of how the photophysical properties are influenced by application of magnetic fields, strong electrical fields, high pressure, and variable temperatures. Optical studies can be made by both emission of absorption changes. Planned equipment upgrades include the introduction of transient grating spectroscopy, extending possibilities with anisotropy work, and moving from solution phase to cover the solid state. A wide battery of quantum chemical software and hardware is available
Roles and Responsibilities
Teaching contemporary physical chemistry presents a tremendous challenge in that most students are afraid of the mathematical component. An important objective for the near future, therefore, is to introduce computer-assisted teaching - where graphical methods are used in place of numerical ones - and to teach those special mathematical skills of direct relevance to chemistry. A longer-term goal is to devise an individual electronic tutor for each student.

Current research is concerned with the design of molecular-based artificial photosynthetic models using a detailed understanding of energy- and electron-transfer processes. This is an extension of earlier work aimed at the development of molecular systems aimed at solar fuels production and relies heavily on the use of photophysical studies. On-going collaborations with synthetic chemists (Dr. R. Ziessel at Strasbourg and Dr. A.C. Benniston at Newcastle) provide the necessary materials for comprehensive examinations. Our work concerns seeking a better understanding of the fundamental principles of charge and energy transfer in molecular systems and involves both experimental and theoretical studies. The main lines of investigation at present relate to (i) the fabrication of artificial light-harvesting arrays capable of efficient capture of sunlight and (ii) the design of molecular systems capable of storing multiple electrons at a catalytic site. This research relies heavily on the use of sophisticated laser spectroscopy for fast kinetic and spectroscopic studies. Additional research is aimed at improving the performance of molecular catalysts for water splitting.. We are also working with industrial companies to promote interest in solar fuels. A wide range of spectroscopic instruments has been constructed in-house, taking advantage of the School machine and electronics workshops.
(i) Photosynthetic organisms are exquisitely arranged so as to capture incident sunlight with high efficacy, and transmit the transient excitation energy to a reaction centre where chemical reactions are initiated. The energy-transfer mechanism is often described by semi-classical models that invoke ‘hopping’ of the wave-packet along discrete energy levels and over considerable distances set in 3-dimensional space. These energy levels combine to form a large peripheral light-harvesting antenna coupled to individual reaction centres. Many attempts have been made to duplicate the essential features of the natural process, ignoring elaborate events such as self-repair and quantum coherence, and great progress has been made in understanding the basic energy-transfer steps. Mostly, these bio-inspired molecular systems have been studied as standalone entities in 2-dimensions, with little consideration given to longer-range energy transfer between moieties embedded in a solid matrix. We have built and studied many molecular arrays of increasing complexity in terms of their ability to function as artificial light-harvesting networks. Rates of intramolecular energy transfer have been measured and compared to theoretical models, allowing for both through-space and through-bond interactions and utilising a multi-pole approach. The work is helping to better define the mechanism of electronic energy transfer in molecular entities. In terms of expanding the dimensionality, it should be noted that some success has been achieved with quantum dots dispersed in a polymeric film and our latest work in this area seeks to build upon this foundation by introducing an organic equivalent that has unique properties.
(ii) What are the major obstacles to the successful introduction of a viable demonstration model that unambiguously verifies the potential for a molecular-based artificial photosynthetic system? In reality there is only one such bottleneck: namely, the need to couple the inherently one-electron photochemistry with the multiple electron fuel formation without using sacrificial redox agents. We propose to solve this critical problem using a unidirectional electron-transfer cascade of the type developed recently in our group (see publication list). These arrays will be attached covalently to [FeS] clusters and the ability to store multiple electrons under illumination will be probed experimentally in the solid state. The array will be coupled to existing artificial light-harvesting panels. The intention is to illustrate, at the level of public lectures, that visible light can be used to split water in a molecular-based system under ambient conditions and that the mechanism can be followed by sophisticated spectroscopy.
