New [(D-terpyridine)-Ru-(D or A-terpyridine)][4-EtPhCO2]2 complexes (D = electron donor group; A = electron acceptor group) as active second-order non linear optical chromophores
Abstract
The dipolar and octupolar contributions of the second order nonlinear optical properties of [(4′-(C6H4-p-D)-2,2′:6′,2′′-terpyridine)-Ru-(4′-(C6H4-p-A)-2,2′:6′,2′′-terpyridine)]Y2 heteroleptic complexes (D and A are donor and acceptor groups, respectively), and related free
