  Structure-Controlled Solventless Thermolytic Synthesis of Uniform Silver Nanodisks

  摘要：

  Monodisperse silver nanodisks are synthesized on the gram scale from a well-characterized layered silver thiolate precursor via thermolysis at 180-225 degrees C under a N-2 atmosphere. XRD, TEM, HRTEM, and AFM analyses indicate that the nanodisks generated at 180 degrees C over 2 h have an average diameter of about 16.1 nm (sigma = +/- 12%) and a thickness of 2.3 nm (sigma = +/- 14%), and they lie on their (111) faces. The disk shape is considered to be predestined by the crystal structure of the precursor. Important aspects regarding the stability of the precursor, the thermolysis temperature, and the annealing time, as well as a possible conversion mechanism, are discussed.

  all chemical systems are conducive to the isolation of single crystals for traditional characterization. Here, small-molecule serial femtosecond crystallography (smSFX) at atomic resolution (0.833 Å) is employed to characterize microcrystalline silver n-alkanethiolates with various alkyl chain lengths at X-ray free electron laser facilities, resolving long-standing controversies regarding the atomic

  新型合成杂化材料及其日益增加的复杂性对单晶 X 射线衍射分析的晶体生长提出了越来越高的要求。不幸的是，并非所有化学系统都有利于分离单晶以进行传统表征。这里，采用原子分辨率 (0.833 Å) 的小分子系列飞秒晶体学 (smSFX) 在 X 射线自由电子激光设备上表征具有各种烷基链长度的微晶正链烷硫醇银，解决了有关原子连通性的长期争议以及层堆叠的奇偶效应。 smSFX 直接从真正未知的粉末中提供高质量的晶体结构，这一功能对于具有众所周知的小或缺陷晶体的系统特别有用。我们提出了正丁硫醇银 (C4)、正己硫醇银 (C6) 和正壬硫醇银 (C9) 的晶体结构。我们证明奇偶效应源于末端甲基的方向及其在堆积效率中的作用。我们还提出了二次奇偶效应，涉及包含偶数链的晶体中的多个镶嵌块，通过选定区域电子衍射测量来识别。最后，我们讨论了用于制备微衍射样品的合成制剂的优点，并将这些晶体的长程有序与自组装单层的长程有序进行了比较。
• Mesogenic behavior of silver thiolates with layered structure in the solid state: covalent soaps

  The family of primary silver thiolate compounds AgSCnH2n+1 (n = 4, 6, 8, 10, 12, 16, and 18), which in the solid state consist of infinity 2[AgSR] layers with the R substituents extending perpendicular to both sides of a central slab of Ag and S atoms, behave as thermotropic liquid crystals. On heating they display successively lamellar (smectic A), cubic, and micellar mesophases; the range of appearance of the two former phases decreases with increasing length of R, so that for n greater-than-or-equal-to 12 only the micellar phase is observed on melting. X-ray diffraction studies on the lamellar phase for n = 6 reveal a packing rather similar to that found in the solid. For n = 18, X-ray diffraction shows that the micellar phase is a hexagonal columnar mesophase, which is understood as being the result of a rearrangement of the solid-state structure to form (AgSR)8 cyclic structures behaving as micelles.
• The self-assembly of a layered material: metal-alkanethiolate bilayers

  Layered materials composed of metal-alkanethiolate units have been synthesized and characterized. The self-assembly occurs at the interface between a metal-ion-containing aqueous phase and an alkanethiol-containing organic phase. Key features of the structure have been determined from X-ray diffraction and infrared spectroscopy measurements. The highly ordered bilayers are characterized by tilted, all-trans alkyl chains. A new model for the inplane structure has been presented, which is based on a hexagonal arrangement of metal atoms in the central plane.

  The first direct characterization of structures of bi-molecular chain assemblies in a self-consistent series of pillared, layered organic-inorganic long-chain silver (n-alkane)thiolates, (AgS(CH2)(n)CH3; n = 5, 6, 9, 11, 15, and 17), is reported using the combined application of infrared transmission spectroscopy and powder X-ray diffraction. The structural attributes elucidated:include quantitative estimates of average chain orientation, chain conformation, chain-chain translational order, interpenetration of the contiguous layers, as well as void characteristics in the chain matrix. The evidence presented here establishes that the layered chain assemblies sandwiched between the inorganic Ag-S backbones in a double-layer arrangement are comprised of an ordered packing of all-trans-extended chains. The average chain in each assembly is oriented vertically away from the quasi-hexagonal Ag-S lattice, in a two-dimensional pseudo-monoclinic arrangement of domains of 60-70 translationally correlated chains. Small interpenetration between the contiguous layers leads to the formation of regularly spaced 1D channels or corridors. The three-dimensional network of 1D channels alternates between the chain layers. All the chain structural characteristics deduced here are, in good conformity with those implied in the model proposed earlier by Dance and co-workers. The present results, together with the previous X-ray analysis for comparable short-chain AgSRs, are used to propose a two-step, hierarchical self-assembly mechanism for the:formation of silver (n-alkyl) thiolates. It is proposed that the primary self-assembly process involves the organization of Ag+ and RS- species into puckered sheets of quasi-hexagonally symmetric 2D lattices, with the chain substituents extending on each side. The subsequent self-assembly of these 2D building blocks in the third dimension via complementary stacking appears to complete the formation of sandwiched bimolecular chain assemblies.
• Phase Behavior of a Structurally Constrained Organic−Inorganic Crystal: Temperature-Dependent Infrared Spectroscopy of Silver <i>n-</i>Dodecanethiolate

  Using temperature-dependent Fourier transform infrared (FTIR) spectroscopy, we probe the molecular level, chain-structural dynamics associated with solid-solid transitions between 25 and 250 degrees C in a layered inorganic-organic silver dodecanethiolate, AgS(CH2)(11)CH3. Spectroscopic evidence presented here establishes two major transitions: the transition occurring at similar to 130 degrees C is characterized by an abrupt, but fully reversible, change in the chain conformational order from an initial all-trans state to the one characterized by mixed or partial chain disorder. The observation of this phase transition is consistent with the previous predictions of a rapid and drastic change in the structural motif from an initial bilayer to the final micellar state. The second transition at about 190 degrees C, which is consistent with the previous assignment of micellar amorphous transition, is furthermore irreversible and represents thermal degradation of the material. Implications of these results for the general family of chain molecular assemblies in constrained molecular environments are discussed.
