The Senate of the Deutschen Forschungsgemeinschaft has established a new Priority Programme entitled ,,Control of London Dispersion Interactions in Molecular Chemistry" (SPP 1807). The programme is designed to run for six years, the present call invites proposals for the first three-year funding period. This Priority Programme aims at a thorough understanding and quantification of London dispersion interactions in molecular systems. These and related short-range electron correlation effects are the driving force for molecular aggregation that play a key role in thermodynamics, molecular recognition, chemical selectivity through transition-state stabilisation, protein folding, enzyme catalysis and other phenonema. While dispersion interactions help rationalise many common phenonema such as well-established ?-? interactions, the related ?-? systems have been examined much less and the concept of ?-? attraction is in its infancy. A primary goal of this programme is the development of chemical design principles that utilises dispersion interactions in the construction of novel molecular structures and in the design of chemical reactions. This can only be achieved through a tight interplay between synthesis, spectroscopy, and theory to quantitatively determine dispersion interactions in chemical (model) systems. The experimental and theoretical capabilities have reached a stage that allows a clear-cut analysis of dispersion interactions. There are many challenges to understand and to utilise dispersion forces for the preparation of novel molecular structures, to elucidate the transition from molecular to bulk properties, and catalysis through fine tuning of dispersion-energy donors for optimising the interactions of ligands and substrates. The focus lies on the following topics:

o structural studies and quantification of dispersion interactions
- quantification of dispersion-energy donors
- design and preparation of novel dispersion-stabilised structures
- dispersion interactions in electronically excited states

o dispersion effects on reactivity and in catalysis
- transition-state stabilisation through dispersion-energy donors
- solvent-induced modulation of dispersion interactions

o theory and spectroscopy as tools for the elucidation of dispersion interactions
- experimental and theoretical method development to address dispersion interactions
- molecular spectroscopy to quantify dispersion effects and to validate theoretical results
Grant proposals should include several of the above aspects and methods or should mention the connection to complementary projects. Joint proposals of several PIs are also possible.
