“…Especially in conjunction with various electron acceptors (e.g., electron-deficient aromatics and heteroaromatics), pyrazole derivatives emerge as highly efficient, tunable light emitters [148][149][150]. Such structural motifs, including pyrazoloquinolines, have been intensively studied in the area of advanced dye chemistry, and most recently as electroluminescent materials [6,151,152], fluorescence sensors [153,154] and second-order nonlinear optical materials [155][156][157].…”

This paper summarises a little over 100 years of research on the synthesis and the photophysical and biological properties of 1H-pyrazolo[3,4-b]quinolines that was published in the years 1911–2021. The main methods of synthesis are described, which include Friedländer condensation, synthesis from anthranilic acid derivatives, multicomponent synthesis and others. The use of this class of compounds as potential fluorescent sensors and biologically active compounds is shown. This review intends to summarize the abovementioned aspects of 1H-pyrazolo[3,4-b]quinoline chemistry. Some of the results that are presented in this publication come from the laboratories of the authors of this review.

“…Increase in optical non-linearity happens when electron charge density distribution is enhanced in excited state or ground state. NLO applications of quinoline derivatives are signi cantly studied and investigated [9][10][11][12][13]. Ultrafast responses, low dielectric constant and broadband electronic responses are the key properties responsible for its non-linear optical properties (NLO).…”

Quinoline Yellow (QY) with the scientific name [sodium 2-(2, 3-dihydro-1,3-dioxo-1H-inden-2-yl) quinoline-6,8-disulfonate] (SQDS) is investigated for its sensing properties as fluorochemosensors and its NLO applications. Pure SQDS is doped with copper ferrite and cerium oxide nanoparticles and studied for changes in spectral results. Change in absorption spectrum is observed depending on the polarity of solvents. Intensity of fluorescence also varies with different type of solvents. Optical characterization for SQDS is carried out via various spectroscopic techniques including UV-VIS spectroscopy, FTIR spectroscopy, Scanning Electron Microscopy and Photo Luminescence (PL) spectroscopy. Optical parameters like extinction coefficient, refractive index and bandgap energy are determined from absorption spectrum for both solution and film samples. XRD characterization is also performed for QY and for nanoparticle doped QY. For investigating Non-Linear optical (NLO) application of QY, films are prepared and optical imaging is performed via Atomic Force Microscopy (AFM). Characterization results are analysed and predicted for application in non-linear optics.

In this study, we developed a selective method for synthesis of multi-substituted quinoline-2-ylphosphonates and quinoline-3-ylphosphonates by copper-or gold-catalyzed reactions of phosphoryl-substituted conjugated ynones with 2′-amino-2,2,2-trifluoroacetophenones. The approach proposed makes it possible to obtain various substituted quinolines in good yields. It is also shown that (4,4,4-trifluoro-3-oxobut-1-yn-1-yl)phosphonate reacts with 2-aminoaryl ketones under non-catalytic conditions with formation of 4-substituted quinoline-2-ylphosphonates in high yields.
