Lay summary
Dieser Vorschlag kombiniert drei zentrale Themen für "Energie und Nachhaltigkeit". Während sich die Ziele der einzelnen Teilprojekte voneinander unterscheiden, schließen sich die zugrunde liegenden chemischen und analytischen Methoden nicht gegenseitig aus, und die vier unterstützten Doktoranden werden von der gegenseitigen Exposition gegenüber der Forschung profitieren. Wir sind an der Spitze der Entwicklung von DSCs mit Farbstoffen auf der Grundlage erdreichhaltiger Metalle, und wir schlagen vor, diese weiter zu DSCs zu entwickeln, die sowohl Farbstoffe als auch Elektrolyte aus nachhaltigen Komponenten verwenden. Ein wesentlicher Grund für unseren Erfolg in diesem Bereich ist die Anwendung hierarchischer Baugruppen. Unsere Methodik wird als "Oberflächen-as-Liganden, Oberflächen-as-Komplexe" (SALSAC) bezeichnet und erweitert die "einfache" Selbstorganisation und Selbstorganisation an Oberflächen auf den schrittweisen und hierarchischen Aufbau neuer Architekturen. Im Teilprojekt B werden wir diese zu multifunktionalen Oberflächen weiterentwickeln. Das Teilprojekt C widmet sich der Entwicklung lichtemittierender Materialien für den Einsatz in lichtemittierenden elektrochemischen Zellen (LECs) und wir konzentrieren uns auf die Verwendung von erdreichem Kupfer. Dieses Teilprojekt wird unsere Kenntnisse über das molekulare Design für kupferbasierte Emitter erweitern und die Ligandentypen diversifizieren, um das Emissionsverhalten zu verbessern.

Abstract

Sub-projects A-C in this proposal combine three themes central to the research goals of our group which lie within the University of Basel's major focus area of 'Energy and Sustainability'. While the goals of each sub-project are distinct from one another, the underlying chemistries and analytical methods are not mutually exclusive, and the four supported doctoral students will benefit from exposure to each other's research. Two doctoral students (Mariia Karpacheva and Isaak Nohara) require support to continue their doctoral studies from SNF grant 200020_162631 (Constable PI). One new doctoral student is requested to further support our efforts in the field of dye-sensitized solar cells (DSCs). We are at the cutting edge of developing DSCs with dyes based on Earth abundant metals and we propose to advance this further to DSCs in whic both dyes and electrolytes made from sustainable components. The additional position is essential if we are to maintain our group's position at the international forefront of sustainable DSC research. A major reason for our success in this field is the application of hierarchical assemblies. Our methodology, is described as 'surfaces-as-ligands, surfaces-as-complexes' (SALSAC) and extends 'simple' self-assembly and self-organization at surfaces to stepwise and hierarchical building up of new architectures. In sub-project B, we will develop this further to encompass multifunctional surfaces. Sub-project C is dedicated to developing light-emissive materials for application in light-emitting electrochemical cells (LECs) and we focus upon the use of Earth abundant copper. This sub-project will advance our knowledge of molecular design for copper-based emitters and will diversify the ligand types in order to enhance emission behaviour.Sub-project A will continue the SNF support of Mariia Karpacheva (currently in Year 1). She will develop photosensitizers and modify electrolytes in DSCs using the Earth abundant metals copper and iron. Karpacheva will focus on (i) the development of heteroleptic iron-containing dyes, with structural modifications of anchoring and ancillary ligands to improve dye performance, and (ii) the development of all-copper DSCs in which both dye and electrolyte comprise copper(I) complexes (heteroleptic and homoleptic, respectively). Sub-project B builds upon our very powerful SALSAC approach to anchoring dyes on solid surfaces. The systematic expansion of the SALSAC methodology envisaged is a unique opportunity to develop a new general approach for controlling assembly processes, defining the structure and modulating the functionality of surfaces. The modularity of the SALSAC method relies upon toolkits of anchoring ligands and ancillary ligands which are optimized for particular target surfaces and particular metal ions. Selectivity in assembly is achieved by the orthogonality of the anchoring domains and the metal-binding domains and selectivity in function through the ancillary ligands.Sub-project C develops Earth abundant copper-based molecular emitters for LECs and will continue to support doctoral student Isaak Nohara (currently in Year 1). Our longstanding collaboration with Dr Henk Bolink and Professor Enrique Ortí (University of Valencia) provides this project with essential support for device measurements and in silico interpretation of emission behaviour; Dr Bolink is one of the world's leading experts in LEC technology with first hand experience in the lighting industry.
