 New functional materials research is frequently driven by a desire to use ‘materials by design’ concepts in the quest for better, ‘greener’ and more efficient materials.    Rational design based on well-known structure/property relationships have been successfully employed to discover materials with hitherto unknown crystal structures or with structures similar to existing family of compounds (e.g. perovskite, pyrochlore.) with targeted properties.  However, such a discovery research frequently leads to totally unexpected but very useful materials with crystal structures and/or properties that are unprecedented.  This talk will describe our recent discovery of new class of highly durable inorganic intense colour pigments based on transition metal cations in trigonal bipyramidal coordination in crystal structures that we were initially exploring for multiferroic properties.  We have now leveraged this ‘unexpected’ discovery to rationally design advanced inorganic oxide based pigments with desired colour as well other functionalities highly desired by colorant industries.
