  Aqueous-stable, Cd- and Pb-free colloidal quantum dots with fluorescence properties in the second near-infrared region (NIR-II, 1000–1400) are highly desirable for non-invasive deep-tissue optical imaging and biosensing. The low band-gap semiconductor, silver chalcogenide, offers a non-toxic and stable alternative to existing Pd, As, Hg and Cd-based NIR-II colloidal quantum dots (QDs). We report facile access

  在第二近红外区域（NIR-II，1000–1400）具有荧光特性的水稳定，无Cd和Pb的胶体量子点，对于非侵入式深层组织光学成像和生物传感是非常需要的。低带隙半导体硫属元素银提供了无毒且稳定的替代品，可替代现有的基于Pd，As，Hg和Cd的NIR-II胶体量子点（QD）。我们报告使用易于制备的硫代/硒脲前体及其类似物，利用Ag 2 X（X = S，Se）QD轻松访问NIR-II发射窗口。这些量子点的水相转移具有很高的荧光量子产率守恒性（保留率高达〜90％）和胶体稳定性。具有可调荧光和高T 1的双峰NIR-II / MRI造影剂通过分别将50个和120个一水合Gd（III）络合物接枝到两个分子上，制得了每个QD 408 mM -1 s -1（尺寸约为2.2 nm）和990 mM -1 s -1每个QD（尺寸约为4.2 nm）弛豫不同尺寸的Ag 2 S QD。纳米晶体的尺寸对于调节Gd有效载荷和弛豫性至关重要。

  [reaction: see text] A mild, efficient, and high-yielding method for the synthesis of N,N'-diaryl cyanoguanidines from their corresponding thioureas under microwave-assisted conditions is described. A series of cyanoguanidines were synthesized containing both electron-donating and electron-withdrawing substituents. The reactions were facilitated by the use of polar solvents along with moderate temperatures

• A greener synthetic protocol for the preparation of carbodiimide

  A new and facile preparation of symmetrical and unsymmetrical 1,3-diaryl and aryl-alkyl carbodiimides via a dehydrosulfurisation of their corresponding thioureas is described. Herein, the classical method of oxidative desulfurisation of thiourea to carbodiimide involving toxic heavy metal oxides (HgO) has been replaced with an easily available, cost-effective and environmentally benign reagent, iodine. Simple reaction conditions, easy purification of the products and high yields are important attributes of the present methodology and perhaps the best alternative from a green chemistry perspective. The only limitation to this method however, is in the preparation of 1,3-dialkyl Substituted carbodiimide. (C) 2009 Elsevier Ltd. All rights reserved.
