A novel 1D Cd-II coordination polymer with 4-sulfobenzoate and 2,2 '-bipyridine containing an approximate rectangular molecular box unit with blue fluorescent emission

The hydrothermal reaction of cadmium hydroxide with 4-sulfobenzoic acid and 2,2 ' -bipyridine yields ID coordination polymer [Cd-2(L)(2)(2,2 ' -bipy)( 2)(H2O)(2))(n) 1 (where L = 4-sulfobenzoic acid), with blue fluorescent emi ssion in which each [Cd-2(L)(2)(2, 2 ' -bipy)(2) (H2O)(2)] unit tan approxi mate rectangular molecular box) is linked together by Il, carboxylate to re sult in the formation of 1D chain coordination polymer.
