The electron donor-acceptor based hybrid ternary nanostructures remains a frontier area of research in designing novel light harvesting devices. Here we report the morphological and photophysical study in Intra-triad and Inter-triad nanoparticles by using electron donating donor-acceptor-donor (D-A-D) type Diketopyrrolopyrrole (DPP) molecule which imparts the advantages of both polymers and small molecules and non fullerene electron acceptor, Naphthalene diimide (NDI) and fullerene based acceptor, Phenyl-C61-butyric acid methyl ester (PCBM). Both these nanostructures were fabricated by modified mini-emulsion technique. The Intra-triad nanostructure contains DPP, NDI and PCBM molecules inside the same matrix and in case of Inter-triad nanostructure, individual nanoparticles are attached together by electrostatic force. The morphological optimizations in hybrid nanostructures are performed with the help of AFM studies. We have further studied the structure mediated charge transfer phenomena and lifetime decay profiles by time resolved photoluminescence and steady state spectroscopy measurements. Due to the favorable energy levels, DPP molecules have been employed here as donor molecule for cascade energy transfer in ternary heterotriad geometric system.

Due to the favorable energy levels, DPP molecules have been employed here as donor molecule for cascade energy transfer in ternary heterotriad geometric system. The steady state and time resolved spectroscopy reveal interesting photophysics about the ternary heterostructures. The Intra-triad system has shown improved charge transfer properties compared to Inter-triad system and could be a futuristic material for opto-electronic applications.

The (E)- and (Z)-styryl isomers of trans-[Pd(CH=CHPh)Br(PMePh 2)2](1a) and [Pd(n2-PhCH= CHPMePh2) Br(PMePh2)] (2a) were prepared, and their C-P reductive elimination (1a – 2a) and C-P oxidative addition (2a – 1a) behaviors examined. Kinetics and thermodynamics of the reactions are strongly affected by E/Z configurations of the styryl group and solvent polarity. Complex (E)-1a readily undergoes C- P reductive elimination in CD2Cl2 as a polar solvent in high selectivity. On the other hand, while the (Z)-isomer of 1a is unreactive toward reductive elimination, (Z)-2a undergoes C-P oxidative addition favorably in nonpolar benzene. X-ray diffraction analysis and DFT calculations for 1a and 2a provided reasonable accounts for these reaction features. Kinetic examinations revealed two types of C- P reductive elimination processes, which involve predissociation and association of the PMePh2 ligand, respectively.

In the palladium-catalyzed cyclization of allenic allylic esters using Pd(dba)2 as catalyst, it was shown that the allene acts as a carbon nucleophile. Intermediates were isolated and stereochemical studies established that the double bond of the allene has attacked the (pi-allyl)palladium intermediate on the face opposite to that of palladium.

The conversion of chemical energy to drive directional motion at the molecular level allows biological systems, ranging from subcellular components to whole organisms, to perform a myriad of dynamic functions and respond to changes in the environment. Directional movement has been demonstrated in artificial molecular systems, but the fundamental motif of unidirectional rotary motion along a single-bond rotary axle induced by metal-catalysed transformation of chemical fuels has not been realized, and the challenge is to couple the metal-centred redox processes to stepwise changes in conformation to arrive at a full unidirectional rotary cycle. Here, we present the design of an organopalladium-based motor and the experimental demonstration of a 360 unidirectional rotary cycle using simple chemical fuels. Exploiting fundamental reactivity principles in organometallic chemistry enables control of directional rotation and offers the potential of harnessing the wealth of opportunities offered by transition-metal-based catalytic conversions to drive motion and dynamic functions.

The diiridium tris(hydrosulfido) complex [Cp*Ir(mu2-SH)3IrCp*]Cl (2; Cp* = eta5-C5Me5) reacted with [NEt4 [SH] at room temperature for 3 h to afford the tetrakis(hydrosulfido) complex [Cp*Ir(SH)(mu2-SH)2IrCp*(SH)] (3). Complex 3 dissolved in benzene is thermally unstable and was converted into the triiridium sulfido-hydrosulfido cluster [(Cp*Ir)3(mu3-S)(mu2-S)(mu2 -SH)2] (4) at 50 C. The related triiridium cluster [(Cp*Ir)3(mu3-S)(mu2-SH)3] Cl (6) was obtained from either the reaction of 3 with 0.5 equiv of [(Cp*IrCl)2(mu2-H)2] or treatment of 2 with an equimolar amount of NEt3. Furthermore, reaction of 3 with 2 equiv of [Pd(PPh3)4 or a [Pd(dba)2]-PPha (dba = dibenzalacetone) mixture gave the Ir2Pd2 mixed-metal sulfido-hydrosulfido cluster [(Cp*Ir)2(SH)(mu3-S)2{Pd(PPh3 )}2(mu2-SH)] (8). X-ray analyses were undertaken to determine the detailed structures of 3, 4, 6, and 8.

A novel palladium-catalyzed interannular selective C-H silylation of 1,1?-biaryl-2-acetamides is described. The combination of palladium catalyst with copper oxidant enables meta- or ortho-selective C-H silylation by employing hexamethyldisilane as a trimethylsilyl source, which relies on the control of NBE derivatives as a switch, thus providing straightforward access to divergent silicon-containing 1,1?-biaryl-2-acetamides.

Despite its industrial importance, very limited mechanistic information on the dehydrogenative coupling of dimethyl phthalate has been reported. Herein we report the detailed mechanism for dehydrogenative coupling of dimethyl phthalate catalyzed by [Pd(OAc)2]/[Cu(OAc)2]/1,10-phenanthroline·H2O (phen·H2O). The solution-phase analysis of the catalytic system by XANES shows the active species to be Pd(II), and EXAFS supports the formation of an (acetato)(dimethyl phthalyl)(phen)palladium(II) complex from [Pd(OAc)2]. A formation pathway of tetramethyl 3,3?,4,4?-biphenyltetracarboxylate via disproportionation of independently prepared [Pd(OAc){C6H3(CO2Me)2-3,4}(phen)] is observed with regeneration of [Pd(OAc)2(phen)].
