Περίληψη:
Enlargement of a self-assembled metal organic rhomboid is achieved via
the organic solid state. The solid-state synthesis of an elongated
organic ligand was achieved by a template directed [2 + 2]
photodimerization in a cocrystal. Initial cocrystals obtained of
resorcinol template and reactant alkene afforded a 1:2 cocrystal with
the alkene in a stacked yet photostable geometry. Cocrystallization
performed in the presence of excess template resulted in a 3:2 cocrystal
composed of novel discrete 10-component hydrogen-bonded
“superassemblies” wherein the alkenes undergo a head-to head [2 +
2] photodimerization. Isolation and reaction of elongated photoproduct
with Cu(II) ions afforded a metal-organic rhomboid of nanoscale
dimensions that hosts small molecules in the solid state as guests.
