The design and synthesis of novel fluorescent heterocyclic dyes is a “hotspot” research area,
due to their favourable photophysical properties and crucial role in charge transfer …

A series of five excited-state intramolecular proton transfer (ESIPT) emitters based on a 2-
(2′-hydroxyphenyl) benzoxazole (HBO) scaffold, functionalized with a mono-or bis …

An optical control of many working optoelectronic systems (real-time sensors, optical
modulators, light amplifiers, or phase retarders) giving efficient optical gain or remote signal …

Abstract Three 1, 3, 5-triphenyl-2-pyrazoline-based sulfonium salt photoinitiators (PIs) were
synthesized, and the relationship between their molecular structures and photophysical and …

Objectives Molecular structures, spectroscopic properties, charge distributions, frontier
orbital energies, nonlinear optical (NLO) properties and molecular docking simulations were …

An original molecular fluorophore displaying single keto (K*) excited-state intramolecular
proton transfer (ESIPT) emission is presented in this article. Substitution at the 3 and 5 …

An investigation has been made to synthesize small organic materials possessing longer
wavelength emission in a simple manner. Three novel pyrazoline compounds were …

Pyrazoline derivatives exhibit potential application as sensitive and selective chemosensors
for the recognition of Fe3+ ions. Their distinctive structure has both donating and accepting …

Abstract In the present work, 4-[(5‑hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)(phenyl)
methyl]-5-methyl-2-phenyl-1, 2-dihydro-3H-pyrazol-3-one (BPZ) was synthesized by one pot …

All-optical switches are introduced which are based on deoxyribonucleic acid (DNA) in the
form of electrospun fibers, where DNA is semi-intercalated with a push–pull, luminescent …
