The molecular second-order nonlinear optical properties of planar (E)-4-[2-(4-(N-methyl-N-hexadecylaminophenyl)ethenyl]pyridine (L-1) and [cis-Ir(CO)(2)ClL1] and of the significantly twisted new chromophores (E)-4-[(5,6,7,8-tetrahydro-5-isoquinolylidene) methyl]-N-methyl-N-hexadecylaniline (L-2) and [cis-Ir(CO)(2)ClL2] are reported, evidencing for the first time that planarity of a conventional (donor)(pi-bridge)(acceptor) structure is not compulsory to reach a large NLO response.

Abstract
The molecular second-order nonlinear optical properties of planar (E)-4-[2-(4-(N-methyl-N-hexadecylaminophenyl)ethenyl]pyridine (L-1) and [cis-Ir(CO)(2)ClL1] and of the significantly twisted new chromophores (E)-4-[(5,6,7,8-tetrahydro-5-isoquinolylidene) methyl]-N-methyl-N-hexadecylaniline (L-2) and [cis-Ir(CO)(2)ClL2] are reported, evidencing for the first time that planarity of a conventional (donor)(pi-bridge)(acceptor) structure is not compulsory to reach a large NLO response.File in questo prodotto:
