(Bentham Science Publishers, 2007-01)The synthesis of backbone-modified nucleic acids has been an area of very intense research over the last two decades. The main reason for this research activity is the instability of nucleic acid based drugs in the ...
-
(American Chemical Society, 2008-01)The role of π-stack induced molecular aggregation on solution and solid-state luminescent properties was investigated for the tricyclodecane substituted bulky (p-phenylenevinylene)s (BTCD-60, with 60% bulky group), ...
-
(Royal Society of Chemistry, 2008-01)π-Conjugated macrocycles consisting of thiophenes and benzenes exhibit benzenoid features for 4nπ macrocycles, whereas (4n + 2)π macrocycles are annulenoid due to rapid interconversion between quinoid and Kekule canonical ...
-
(Elsevier B.V., 2008-02)The synthesis of cyanuryl PNA monomer (CyaPNA) 6 was achieved by direct N-monoalkylation of cyanuric acid with N-(2-Boc-aminoethyl)-N′-(bromoacetyl)glycyl ethyl ester 4. Compound 6 was incorporated as a T-mimic into PNA ...
-
(American Chemical Society, 2008-02)Ferrocene-linked bis(nucleobase) (1a−c) and chimeric nucleobase (1d) conjugates have been synthesized from mono- and bis(hydroxybutyl)ferrocene 6 via Mitsunobu reaction as the key step. X-ray crystallographic studies of ...
-
(American Chemical Society, 2008-02)Isophlorins and its analogues bridge the structural features between porphyrins and annulenes. Invariably they are known to be unstable but can be stabilized by appropriate substituents in the core and periphery of a ...
-
(Wiley, 2008-04)A novel melt transurethane polycondensation route for polyurethanes under solvent‐free and nonisocyanate condition was developed for soluble and thermally stable aliphatic or aromatic polyurethanes. The new transurethane ...
-
(Oxford University Press, 2008-04)To better understand DNA recognition and transcription activity by SATB1, the T-lineage-enriched chromatin organizer and transcription factor, we have determined its optimal DNA-binding sequence by random oligonucleotide ...
-
(Wiley, 2008-05)We report a novel poly (m‐phenylenevinylene)s and their copolymers based on renewable resource starting material 3‐pentadecylphenol to trace the Forster energy transfer process and molecular aggregation in the π‐conjugated ...
-
(American Chemical Society, 2008-08)Here, we report a synthesis of novel polyaniline nanospheres bearing mono- and bishydroxyl functional groups to trace the molecular interactions at the nanosurfaces through vitamin C sensing. Two new aniline monomers were ...
-
(American Chemical Society, 2008-09)Here, we report a unique soft templating approach based on an in-built amphiphilic azobenzenesulfonic acid for tuning various types of polyaniline nanomaterials such as fibers, rods, spheres, and tubes. The dopant molecule ...
-
(Wiley, 2008-09)We report a new series of polyurethane–oligo(phenylenevinylene) (OPV) random copolymers and their self‐assembled nanomaterials such as pores, vesicles, and luminescent spheres. The polymers were synthesized through melt ...
-
(AIP Publishing, 2009-01)Vibrationally resolved photoelectron spectra of OCS+(C Σ2+) are used to probe coupling between photoelectron motion and molecular vibration for a simple asymmetric system. Spectra are reported over the photon energy range ...
-
(AIP Publishing, 2009-01)Recent computed and experimental results for ICN, BF3 and C6F6 will be presented. In ICN we consider the ionization leading to the X2 -1/2,3/2 states of ICN+. We show how the geometry dependence of the initial state orbital ...
-
(American Chemical Society, 2009-03)We report a new ring banded supramolecular structure in thermotropic liquid crystalline oligo(phenylenevinylene) (OPV) via a melt crystallization process. A series of structurally different OPV molecules were synthesized ...
-
(Wiley, 2009-04)We report an anionic surfactant approach for size and shape control in polyaniline, polypyrrole, and their polyaniline‐co‐polypyrrole random copolymer nanomaterials. A renewable resource azobenzenesulfonic acid anionic ...
-
(Wiley, 2009-05)A new series of symmetrically substituted bulky PPV‐copolymers based on poly(bis‐2,5‐(2‐ethylhexyloxy)‐1,4‐phenylenevinylene) (BEH‐PPV) bearing tricyclodecane (TCD) pendants were synthesized to study the effect of chain ...
-
(AIP Publishing, 2009-07)The vibrational branching ratios in the photoionization of C6F6 leading to the C B22u state of C6F+6 are considered. Computational and experimental data are compared for the excitation of two totally symmetric modes. ...
-
(American Chemical Society, 2009-07)We report a soft template approach based on a custom-designed novel surfactant-cum-dopant for size and shape tuning of polyaniline nanomaterials such as nanofibers and nanotapes via emulsion and dispersion polymerization ...
-
(Wiley, 2009-08)We report reproducible large‐scale synthesis of polyaniline (PANI) nanofibers up to 100 g scale via micelle mediated soft template approach. A unique built‐in amphiphilic azobenzenesulfonic acid based on renewable resource ...
