Formation principle of
templated vanadium oxo-species
Dr. Alex Norquist
Haverford College
Abstract
A set of formation principles governing organically templated vanadium oxo-compounds are
described in the context of a series of new compounds. First, the compositions of the reaction
mixtures dictate the nature of the primary building units from which the compounds are formed.
These compositions are affected by both solution properties (pH) and relative concentrations.
Second, charge density matching between the cationic and anionic components directly affects
the way in which the primary building units form larger secondary building units. Third, weaker
interactions, including hydrogen-bonding, sterics and symmetry all affect the resulting structure.
Finally, a machine learning approach to improve the reactions from which these compounds are
synthesized will be discussed.
