There is always a need for efficient luminescent materials with simple synthesis and
possible ease of hydrogen atom or functional group manipulation for use in different …

Intramolecular charge transfer (ICT) is an important factor in the nonlinear optical (NLO)
properties of organic molecules. In order to study the effect of ICT on two-photon absorption …

Pigments with unique optical features are always sought after in realizing superior security
features to protect authentic documents/products against forgery. The present study reports …

Time-resolved femtosecond transient absorption (fs-TA) spectroscopy was used to measure
the multi-color fluorescence of two donor-π-acceptor (D-π-A) models based on (2-(4 …

Mechanochromic luminescent (MCL) materials have attracted great attention in the fields of
sensing, memory chips, and anti-counterfeiting. However, most MCL materials only display a …

Hybrids containing both chalcone and benzothiadiazole (BTD) moieties were synthesized
and photophysically characterized. The compounds display either chalcone-BTD-chalcone …

A series of novel quadrupolar push-pull molecules based on quinoxaline moiety as an
electron acceptor, biphenyl as a spacer and methoxy groups as electron donors was …

Three coumarin-triphenylamine chalcone derivatives (5a-c) with push-pull structures of type
A-π-D and D-π-A-π-D were synthesized, varying the substituent at position 7 of coumarin …

Seven novel donor–acceptor-donor type push–pull quadrupolar quinoxaline scaffolds
exhibiting blue or green emission in solution were synthesised in good yields by Heck …

Aggregation-induced emission (AIE) fluorescent molecules with unique photoelectric
properties have received extensive attention due to the wide range of applications. In this …
