In this study, a new series of substituted 1,3,4-thiadiazol-2(3H)-one derivatives I [R = Et, CH2CH=CH2, cyclohexylmethyl, etc.] was synthesized in yields ranging from 42 to 70% via reaction of alkyl bromides with 1-(4-chlorophenyl)-2-((5-methyl-1,3,4-thiadiazol-2-yl)thio)ethanol with an interesting mechanism that involved internal nucleophilic substitution followed by an SN2-type nucleophilic substitution. First, 1-(4-chlorophenyl)-2-((5-methyl-1,3,4-thiadiazol-2-yl)thio)ethanone was synthesized from the reaction of 5-methyl-1,3,4-thiadiazole-2-thiol with 2-bromo-1-(4-chlorophenyl)ethanone which underwent reduction to afford 1-(4-chlorophenyl)-2-((5-methyl-1,3,4-thiadiazol-2-yl)thio)ethanol. The advantages of this protocol were synthesis of target compounds under mild conditions using simple synthetic methods and obtaining them without phosgene.

First examples of multichain (polycatenar) compounds, based on the π-conjugated [1]benzothieno[3,2-b]benzothiophene unit (I, R = alkyl homologs) are designed, synthesized, and their soft self-assembly and charge carrier mobility are investigated. These compounds, terminated by the new fan-shaped 2-brominated 3,4,5-trialkoxybenzoate moiety, form bicontinuous cubic liquid crystalline (LC) phases with helical network structure over extremely wide temperature ranges (>200 K), including ambient temperature Compounds with short chains show an achiral cubic phase with the double network, which upon increasing the chain length, is at first replaced by a tetragonal 3D phase and then by a mirror symmetry is broken triple network cubic phase. In the networks, the capability of bypassing defects provides enhanced charge carrier mobility compared to imperfectly aligned columnar phases, and the charge transportation is non-dispersive, as only rarely observed for LC materials. At the transition to a semicrystalline helical network phase, the conductivity is further enhanced by almost one order of magnitude. In addition, a mirror symmetry broken isotropic liquid phase is formed beside the 3D phases, which upon chain elongation is removed and replaced by a hexagonal columnar LC phase.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 1-Bromoundecane, is researched, Molecular C11H23Br, CAS is 693-67-4, about Effect of n-alkyl substitution on Cu(II)-selective chemosensing of rhodamine B derivatives, the main research direction is alkyl substitution copper fluorescent sensor rhodamine B derivative.Recommanded Product: 693-67-4.

Rhodamine B hydrazide-based mol. probes (1-10) were synthesized by derivatization with n-alkyl chains of different lengths at the hydrazide amino end. These probes exhibited selective absorption (A∼557) and fluorescence (I∼580) ‘off-on’ signal transduction along with a colorless → magenta color transition in the presence of Cu(II) ions among all the competitive metal ions investigated. The effective coordination of these probes to Cu(II) ions under the investigated environment forming [Cu·L]2+ (L = 1-5) and [Cu·L2]2+ (L = 6-10) complexes led to their spiro-ring opening, which in turn was expressed through signatory spectral peaks of ring-opened rhodamine. All these probes exhibited Cu(II) selectivity in signalling despite structural modifications to the core receptor unit through variation of the nature of the alkyl substituents. However, the sensitivity of the signalling and kinetics of the spiro-ring opening varied and could be correlated with the number of carbon atoms present in the n-alkyl substituents. Structural elucidation with X-ray diffraction and X-ray photoemission spectroscopic analyses provided further insight into the structure-function correlation in their Cu(II) complexes. These probes with Cu(II) coordination showed selectivity in signalling, high complexation affinity (log Ka = 4.8-8.8), high sensitivity (LOD = 4.1-80 nM), fast response time (rate = 0.0017-0.0159 s-1) and reversibility with counter anions, which ascertained their potential utility as chemosensors for Cu(II) ion detection.

The thermal behavior, including the cold crystallization, of alkyl-derivatized Sudan III (1-[4-(phenylazo)phenylazo]-2-naphthol), SD3-OCn, was investigated. Its structural flexibility due to the two azo groups caused the formation of plural crystal structures, which further resulted in complex cold crystallization A metastable nonflat structure and a thermodynamically stable flat structure resulted in the two sets of crystallization and melting behavior during the heating process. Further, the change in the alkyl chain length caused variations in the crystallization rate and crystallinity, thus systematically changing the cold crystallization behavior. It was proven that the high mobility of the Ph group triggered supercooling and cold crystallization and that the alkyl chain correspondingly controlled the thermal behavior.

Safety of 1-Bromoundecane. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 1-Bromoundecane, is researched, Molecular C11H23Br, CAS is 693-67-4, about Dictating Nanoparticle Assembly via Systems-Level Control of Molecular Multivalency. Author is Santos, Peter J.; Cao, Zhen; Zhang, Jianyuan; Alexander-Katz, Alfredo; Macfarlane, Robert J..

Nanoparticle assembly can be controlled by multivalent binding interactions between surface ligands, indicating that more precise control over these interactions is important to design complex nanoscale architectures. It has been well-established in natural materials that the arrangement of different mol. species in three dimensions can affect the ability of individual supramol. units to coordinate their binding, thereby regulating the strength and specificity of their collective mol. interactions. However, in artificial systems, limited examples exist that quant. demonstrate how changes in nanoscale geometry can be used to rationally modulate the thermodn. of individual mol. binding interactions. As a result, the use of nanoscale design features to regulate mol. bonding remains an underutilized design handle to control nanomaterials synthesis. Here we demonstrate a polymer-coated nanoparticle material where supramol. bonding and nanoscale structure are used in conjunction to dictate the thermodn. of their multivalent interactions, resulting in emergent bundling of supramol. binding groups that would not be expected on the basis of the mol. structures alone. Addnl., we show that these emergent phenomena can controllably alter the superlattice symmetry by using the mesoscale particle arrangement to alter the thermodn. of the supramol. bonding behavior. The ability to rationally program mol. multivalency via a systems-level approach therefore provides a major step forward in the assembly of complex artificial structures, with implications for future designs of both nanoparticle- and supramol.-based materials.
