TODO - In    this    presentation,    we    demonstrate    how    principles    of    supramolecular  chemistry  involving  molecules  that  function  as  linear  templates  can  be  used  to  direct  the  formation  of  finite  molecular  assemblies  with  components  that  react  to  form  covalent  bonds.    We  demonstrate  how  forces  such  as  hydrogen  bonds  and  coordination  bonds can be used to direct the construction of molecules.  The targets include  linear  and  bent  cyclophanes,  as  well  as  molecular  ladders.    The ability to construct complex molecules in the solid state relies on an   ability   of   the   templates   to   insulate   reactants   from   vexatious   structural effects of molecular close packing, effects which have made directing the formation the covalent bonds in organic solids difficult to control.    Thus,  the  templates  are  able  to  adapt  to  changes  to  size  and  shape  of  the  reactants  and  thereby  provide  a  mean  to  control  the  size  and  shape  of  the  resulting  products.    In  that  way,  the  covalent-bonding-forming  process  provides  a  means  to  covalently  capture  the  geometry   of   reactants   within   supramolecular   architectures   with   structures  largely  independent  of  long-range  packing.    The  molecular  targets  form  in  the  organized,  solvent-free  environment  of  the  solid  state in 100% yield and gram quantities.
