Journal ArticleDOI

Twisted π-System Chromophores for All-Optical Switching

TL;DR: An experimental and theoretical study shows that twisted chromophores with twisted π-electron systems possess very large values of the real part of the cubic hyperpolarizability, γ, which is responsible for nonlinear refraction and offers promise for applications in all-optical switching.
Journal ArticleDOI

Vapor Phase Self-Assembly of Molecular Gate Dielectrics for Thin Film Transistors

TL;DR: Organic-inorganic films grown entirely via a vapor-phase deposition process and composed of highly polarizable molecular structures are investigated as gate dielectrics in organic field-effect transistors (OFETs).
Journal ArticleDOI

Self-assembly from the gas-phase: design and implementation of small-molecule chromophore precursors with large nonlinear optical responses.

TL;DR: The computational modeling, synthesis, and characterization of a series of eight heteroaromatic organic chromophores, designed to self-organize from the vapor phase via directed hydrogen-bond networks, into acentric thin films, are reported.
Journal ArticleDOI

Ultra-High-Response, Multiply Twisted Electro-optic Chromophores: Influence of π-System Elongation and Interplanar Torsion on Hyperpolarizability

TL;DR: The systematic synthesis, structural, optical spectroscopic, and second-order nonlinear optical (NLO) characterization of a series of donor-acceptor poly-arylene chromophores which have heretofore unachieved π-extension and substantial twisting from planarity are reported.
Journal ArticleDOI

Structure−Performance Correlations in Vapor Phase Deposited Self-Assembled Nanodielectrics for Organic Field-Effect Transistors

TL;DR: It is shown here that the metal-insulator-semiconductor (MIS) and OFET device electrical properties are sensitive to the v-SAND molecular dipolar orientation.
