“…Mao et al presented a series of organic dyes (designated Q5, Q6) based on quinoline as an electron-deficient p-linker, and introduce push-pull conjugated dyes, synthesized by Riley oxidation of -CH 3 followed by Knoevenagel condensation [79]. The four dyes bearing either quinazoline or quinoline as conjugated bridges in the chromophore with a diphenylamine moiety were synthesized (designated Q7-Q10 [80]).…”

Among many chemical compounds synthesized for third-generation photovoltaic applications, quinoline derivatives have recently gained popularity. This work reviews the latest developments in the quinoline derivatives (metal complexes) for applications in the photovoltaic cells. Their properties for photovoltaic applications are detailed: absorption spectra, energy levels, and other achievements presented by the authors. We have also outlined various methods for testing the compounds for application. Finally, we present the implementation of quinoline derivatives in photovoltaic cells. Their architecture and design are described, and also, the performance for polymer solar cells and dye-synthesized solar cells was highlighted. We have described their performance and characteristics. We have also pointed out other, non-photovoltaic applications for quinoline derivatives. It has been demonstrated and described that quinoline derivatives are good materials for the emission layer of organic light-emitting diodes (OLEDs) and are also used in transistors. The compounds are also being considered as materials for biomedical applications.

“…Many studies have previously described the effects of altering the donor or acceptor portions of these sensitizers [5,6,16,32]. However, the π-bridge also plays an important role in the overall D-π-A system, and over the last few years, more papers have focused on modifying that region of the molecule [33][34][35][36]. These accounts have substituted various conjugated groups into the π-bridge but have not investigated the effect of heteroatom substitution.…”

Organic donor-pi-acceptor sensitizers are a promising path to achieving cheaper and more efficient dye sensitized solar cells. The π-bridge plays an important part in the photovoltaic properties of the dye, and sulfur systems, like thiophene, have been favorites for this role. We aim to investigate the change in photovoltaic properties for systems that utilize heteroatoms besides sulfur. Using density functional theory, we have investigated the spectroscopic and electronic properties of the D5 organic dye upon heteroatom substitution for sulfur in the π-bridge. We substituted for sulfur with pnictogens, chalcogens, and various other elements in the second row of the periodic table. We find the larger elements reduce the HOMO-LUMO gap, red shift the absorption spectrum, increase the dipole moment and are energetically favorable for electron injection. In particular, π-bridge systems utilizing selenium or phosphorus, instead of the more prevalent sulfur, could prove to be more efficient based on our analysis of photovoltaic properties.

Organic materials development, especially in terms of nonlinear optical (NLO) performance, has become progressively more significant owing to their rising and promising applications in potential photonic devices. Organic moieties such as carbazole and quinoline play a vital role in charge transfer applications in optoelectronics. This study reports and characterizes the donor–acceptor–donor–π–acceptor (D–A–D–π–A) configured novel designed compounds, namely, Q3D1–Q3D3, Q4D1–Q1D2, and Q5D1. We further analyze the structure–property relationship between the quinoline–carbazole compounds for which density functional theory (DFT) and time-dependent DFT (TDDFT) calculations were performed at the B3LYP/6-311G(d,p) level to obtain the optimized geometries, natural bonding orbital (NBO), NLO analysis, electronic properties, and absorption spectra of all mentioned compounds. The computed values of λmax, 364, 360, and 361 nm for Q3, Q4, and Q5 show good agreement of their experimental values: 349, 347, and 323 nm, respectively. The designed compounds (Q3D1–Q5D1) exhibited a smaller energy gap with a maximum redshift than the reference molecules (Q3–Q5), which govern their promising NLO behavior. The NBO evaluation revealed that the extended hyperconjugation stabilizes these systems and caused a promising NLO response. The dipole polarizabilities and hyperpolarizability (β) values of Q3D1–Q3D3, Q4D1-Q1D2, and Q5D1 exceed those of the reference Q3, Q4, and Q5 molecules. These data suggest that the NLO active compounds, Q3D1–Q3D3, Q4D1–Q1D2, and Q5D1, may find their place in future hi-tech optical devices.
