Dimerization and Isomerism Effects on Two-Photon Absorption of Tetraphenylethene Derivatives and Molecular Design for Two-Photon Absorption Materials.

The two-photon absorption (TPA) properties of a new tetraphenylethene derivative and its covalent dimers have been calculated employing the density functional response theory. It is found that linear arrangement of branches can give rise to a cooperative TPA behavior. Partial planarity and linear arrangement are the possible reasons for the observed aggregation-induced TPA enhancement.

Synthesis and pharmacological investigation of aralkyl diamine derivatives as potential triple reuptake inhibitors.

A series of aralkyl diamine derivatives were designed, synthesized, and evaluated for their triple reuptake inhibitory abilities. Compounds 18c (5-HT, NE, DA, IC50 = 389, 69, 238 nM), 36a (5-HT, NE, DA, IC50 = 378, 477, 247 nM), and 36d (5-HT, NE, DA, IC50 = 501, 206, 357 nM) showed in vivo activities in the rat forced swim test at 5, 10, and 20 mg/kg PO. 36a was identified as the most promising candidate in this study.
