Control of Molecular structure in the generation of Highly Luminescent Liquid Crystalline Perylenebisimide Derivatives: Synthesis, Liquid Crystalline and Photophysical Properties

Jancy, B; Asha, S K (American Chemical Society, 2006)

We report here, for the first time, the role of the molecular design on the liquid crystalline and solid-state photoluminescent properties of soluble and thermally stable liquid crystalline perylenebisimide derivatives. A ...
Hydrogen bonding and rate enhancement in the photoinduced polymerization of telechelic urethane methacrylates based on a cycloaliphatic system: Tricyclodecane dimethanol

Deepak, V D; Rajan, J; Asha, S K (Wiley, 2006)

A new class of telechelic urethane methacrylic crosslinkers, based on a cycloaliphatic system (tricyclodecane dimethanol and tricyclodecane monomethanol), was synthesized. The synthesis was achieved by a two-step condensation ...
Hydrogen-bonding-induced conformational change from J to H aggregate in novel highly fluorescent liquid-crystalline perylenebisimides

Jancy, B; Asha, S K (American Chemical Society, 2008)

A series of highly fluorescent liquid-crystalline perylenebisimide molecules having amide or ester linkage and end-capped by phenyl, monododecyloxy phenyl, or tridodecyloxy phenyl units have been synthesized and fully ...
Nonlinear optical, fluorescence and liquid crystalline properties of novel azobenzene polymers and their oligomers

Smitha, P (Chemical Sciences and Technology Division, National Institute for Interdisciplinary Science and Technology(CSIR), Thiruvananthapuram., 2008-04)
Photophysical investigation into the self-organization in pyrene-based urethane methacrylate comb polymer

Deepak, V D; Asha, S K (American Chemical Society, 2009)

A side chain urethane methacrylate polymer with pendant pyrene units was synthesized and investigated for its self-organizing process in solution by UV-vis and fluorescence spectra and in film by scanning electron microscopy ...
Random and AB diblock copolymers of tricyclodecanemethanol urethane methacrylate with styrene: Synthesis and morphology characterization

Deepak, V D; Asha, S K (Wiley, 2008)

A monomer design having a bulky terminal tricyclodecane (TCD) unit linked via hydrogen bondable urethane to an ethyleneoxy methacrylate unit, and capable of generating three-dimensional honeycomb patterns upon solvent ...
Self-organization-induced three-dimensional honeycomb pattern in structure-controlled bulky methacrylate polymers: Synthesis, morphology, and mechanism of pore formation

Deepak, V D; Asha, S K (American Chemical Society, 2006)

Here we report, for the first time, a novel molecular design for three-dimensional honeycomb structures through a self-organization of hydrogen-bonded bulky anchoring group in a methacrylic polymer backbone. The polymerizable ...
Solvent-Induced self-assembly in cardanol-based urethane methacrylate comb polymers

Rekha, N; Asha, S K (Wiley, 2009)

We report side chain urethane-methacrylate comb polymers based on the renewable resource cardanol and its saturated analogue 3-pentadecyl phenol and their self-assembly into pores, spheres, vesicles, tubes, and so forth. ...
Synthesis and FTIR spectroscopic investigation of the UV curing kinetics of telechelic urethane methacrylate crosslinkers based on the renewable resource-cardanol

Rekha, N; Asha, S K (Wiley, 2008)

UV curable telechelic urethane-methacrylate crosslinkers based on the natural resource-cardanol was synthesized in a one pot synthetic step involving end capping of isophorone diisocyanate with one equivalent of hydroxyethyl ...
Synthesis and self-organization properties of copolyurethanes based on perylenediimide and naphthalenediimide units

Jancy, B; Asha, S K (Wiley, 2009)

A series of perylene and naphthalene diimide-containing random copolyurethanes with different ratios of perylene/naphthalene diimide content was synthesized and characterized. Copolymerization improved the solubility of ...
Synthesis, characterization, and hyperpolarizability measurements of main-chain azobenzene molecules

Smitha, P; Asha, S K; Pillai, C K S (Wiley-Blackwell, 2005)

A series of new AB type azobenzene monomers based on various substituted phenols and higher order fused/extended aromatic rings were synthesized and their hyper-polarizability tensor beta determined by hyper-Rayleigh ...
