Many pyrimidine derivatives are known to crystallize in multiple polymorphic and/or hydrated forms.  Herein, two-dimensional siloxane templates with various terminal functionalities are explored as templates to induce heterogeneous nucleation and polymorph selection in two different substituted uracils.  Both slow-evaporation and drop-cast crystallization methods are investigated in an effort to elucidate the specific substrate-crystal interactions which lead to phase control.    <br/>
