The very peculiar characteristics of zwitterions, as well as a clearand unambiguous
definition, have been overlooked in past literature. However, these compounds are …

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

Ten organoimido polyoxometalate (POM)-based chromophores have been synthesized and
studied by hyper-Rayleigh scattering (HRS), Stark and Resonance Raman spectroscopies …

We show that polyoxometalates (POMs) are an excellent redox-active acceptor on which to
base high performance 2nd order non-linear optical (NLO) chromophores. This is …

We present the first study of arylimido-polyoxometalate nonlinear optical (NLO)
chromophores with two-dimensional (2D) structures, and a comparison with one …

Abstract N, N′‐Disubstituted bipyridinium (viologen) and N‐monosubstituted bipyridinium
compounds are well known for their electron‐transfer (ET) photochromic behavior. Their …

Electrochemically switched 2nd order non‐linear optical responses have been
demonstrated for the first time in polyoxometalates (POMs), with an arylimido‐derivative …

Lanthanide (III) ion (Ln (III)) sensing has become a major research area owing to its
intriguing prospect in clinic, biology, and environmental studies. However, the existing …

Rigid pyrazino-phenanthroline based donor-π-acceptor-π-auxiliary acceptor type
compounds have been studied for their linear and non-linear optical properties. The non …

In the last few decades optical imaging techniques based on nonlinear optical properties
have been of interest for biosensing applications. This work focuses on two isostructural and …
