Synthesis and two-photon absorption properties of unsymmetrical metallosalophen complexes
摘要:
Several new unsymmetrical metallosalphen complexes derived from the condensation of a monoimine and salicylaldehyde in the presence of a transition metal ion as a template have been synthesized and characterized. Their linear and third-order non-linear optical (NLO) properties have been investigated in detail. With different substituted donor or acceptor groups at the 5-position of the salicylidene fragment, these metallosalophen complexes exhibit slightly different two-photon absorption (TPA) cross-section sigma((2)) values. Theoretical calculations based on density functional theory were also carried out to help with the interpretations of the experimental results. (c) 2012 Elsevier Ltd. All rights reserved.
