Effect of the 1D/2D dimensionality in copper and silver thiolate coordination polymers on their photophysical properties

Abstract

A series of four new copper and silver-thiolate, [M(m-SPhCO₂R)]_n (M = Cu, Ag and R = H, Me), coordination polymers is reported. The study shows that the hydrogen bonding between the carboxylic acids directs the formation of a 2D structure associated with poor photoemission, while the steric hindrance of the ester groups allows the assembly of a 1D network coupled with bright luminescence.
