Journal ArticleDOI
Realization of Highly Efficient Red Phosphorescence from Bis-Tridentate Iridium(III) Phosphors.
TL;DR: Design of five bis-tridentate Ir(III) metal complexes, to which both of their monoanionic ancillary and dianionic chromophoric chelate were functionalized derivative of 2-pyrazolyl-6-phenylpyridine, confirmed that the T1 excited state of all investigated Ir( III) complexes shows a mixed metal-to-ligand charge transfer (MLCT), intraligand chargeTransfer (ILCT), ligand-to
Journal ArticleDOI
Short hybrid polymer/sol-gel silica waveguide switches with high in-device electro-optic coefficient based on photostable chromophore
TL;DR: In this paper, a short polymeric directional coupler switches based on hybrid EO polymer/sol-gel silica waveguides were used to achieve an in-device EO coefficient of 160 pm/V at 1550 nm.
Proceedings ArticleDOI

TL;DR: In this paper, the results obtained from these poled binary organic glass materials (r 33 as high as 310 pm/V at 1.31μm) are the highest values ever reported which are >10 times of the commercial lithium niobate crystals.
Journal ArticleDOI

TL;DR: In this article, a strategy to decouple self-healing and mechanical properties from the covalent structure of supramolecular polymers is proposed, which is based on non-covalent π-π interactions between naphthalene diimide (NDI) and pyrene derivatives.
Journal ArticleDOI
Single-cell patterning and adhesion on chemically engineered poly(dimethylsiloxane) surface.
TL;DR: By combining soft lithography and surface engineering, a simple methodology produced single cell arrays on biocompatible substrates using chemically modified poly(dimethylsiloxane) (PDMS) substrates.
