Abstract
A new multi-branched model Cu(II) complex based on curcumin, namely CuL2(I) (НL = (1E,4Z,6E)-1,7-bis(4-(4-bromobutoxy)-3-methoxyphenyl)-5-hydroxyhepta-1,4,6-trien-3-one, C29H34O6Br2), was prepared and its two-photon absorption (TPA) properties were described in the femtosecond regime. The experimental results showed that complex I exhibited relatively strong and wide-dispersed two-photon activities in the near-infrared (NIR) regime and the calculated TPA cross section of complex I was as high as 872 GM (1 GM = 10−50 cm4 s photon−1) in DMF. Additionally, complex I revealed its potential application as a biological fluorescent probe due to its good photo-physical properties and low cytotoxicity, as well as excellent stability and specificity for optical imaging of tumors. Complex I was characterized by single crystal X-ray diffraction too (CIF file CCDC no. 1412447).
