Abstract

The thiol-substituted B₁₂-cluster mercaptoundecahydro-closo-dodecaborate Na₂[B₁₂H₁₁SH] (BSH) was successfully attached to a poly(amido)amine (PAMAM) dendrimer, which contains a bis(decyloxy)decane core. The physical modification of single-walled carbon nanotubes (SWCNTs) with dendrimer(SB₁₂)₄ afforded a SWCNT/dendrimer(SB₁₂)₄ nanohybrid that exhibited NIR-I-to-NIR-II fluorescence. Herein, we describe a promising strategy for in vivo imaging of boron clusters that may be widely applicable to boron neutron capture therapy.

含巯基的树枝状聚合物（Na2B12H11S）对碳纳米管的物理改性

巯基取代的b12簇巯基十氢近十二硼酸钠[B12H11SH] (BSH)成功地连接到含有双(癸氧基)十烷核的聚(胺)胺(PAMAM)树状聚合物上。用树状大分子(SB12)4对单壁碳纳米管(SWCNTs)进行物理修饰，得到了具有NIR-I-to-NIR-II荧光的SWCNTs /树状大分子(SB12)4纳米杂化物。在此，我们描述了一种有前途的硼团簇体内成像策略，可能广泛适用于硼中子捕获治疗。

期刊介绍： Heteroatom Chemistry brings together a broad, interdisciplinary group of chemists who work with compounds containing main-group elements of groups 13 through 17 of the Periodic Table, and certain other related elements. The fundamental reactivity under investigation should, in all cases, be concentrated about the heteroatoms. It does not matter whether the compounds being studied are acyclic or cyclic; saturated or unsaturated; monomeric, polymeric or solid state in nature; inorganic, organic, or naturally occurring, so long as the heteroatom is playing an essential role. Computational, experimental, and combined studies are equally welcome. Subject areas include (but are by no means limited to): -Reactivity about heteroatoms for accessing new products or synthetic pathways -Unusual valency main-group element compounds and their properties -Highly strained (e.g. bridged) main-group element compounds and their properties -Photochemical or thermal cleavage of heteroatom bonds and the resulting reactivity -Uncommon and structurally interesting heteroatom-containing species (including those containing multiple bonds and catenation) -Stereochemistry of compounds due to the presence of heteroatoms -Neighboring group effects of heteroatoms on the properties of compounds -Main-group element compounds as analogues of transition metal compounds -Variations and new results from established and named reactions (including Wittig, Kabachnik–Fields, Pudovik, Arbuzov, Hirao, and Mitsunobu) -Catalysis and green syntheses enabled by heteroatoms and their chemistry -Applications of compounds where the heteroatom plays a critical role. In addition to original research articles on heteroatom chemistry, the journal welcomes focused review articles that examine the state of the art, identify emerging trends, and suggest future directions for developing fields.
