Computational modeling reveals that, by substitutional modification of interplanar dihedral
angles in a series of quinopyrans, both the optical absorption cross section and the first …

To reexamine the established “auxiliary donor” effect of thiophene in nonlinear optical (NLO)
chromophores, we have prepared two isomeric donor− acceptor azo dyes, differing only in …

In this paper, we describe the second-order nonlinear optical properties of a series of 1, 3-
dithiole-based electron donor− acceptor systems incorporating proaromatic donor and …

Conspectus Materials with large nonlinear optical (NLO) response have the ability to
manipulate the frequency and phase of incident light and exhibit phenomena that form the …

A series of push− pull chromophores comprising a dimethylamino or diphenylamino electron-
donating functionality and a cationic benzothiazolium acceptor with an additional electron …

The linear and nonlinear optical properties of donor− acceptor π-electron chromophores
having conjugated bridges varying in aromaticity and electron excessivity are investigated …

The systematic synthesis, structural, optical spectroscopic, and second-order nonlinear
optical (NLO) characterization of a series of donor–acceptor poly-arylene chromophores …

A series of mono-, bis-, tris-, and tetrakis (porphinato) zinc (II)(PZn)-elaborated ruthenium (II)
bis (terpyridine)(Ru) complexes have been synthesized in which an ethyne unit connects the …

We describe a series of nine new complex salts in which electron-rich RuII or FeII centers
are connected via π-conjugated bridges to six electron-accepting N-methyl-/N …

A new series of push–pull porphyrin-based chromophores with unusually large static first
hyperpolarizabilities are designed on the basis of coupled-perturbed Hartree–Fock and …
