“…Now in 2019, the synthesis of a juloldine‐coumarin‐7‐nitro‐1,2,3‐benzoxadiazole hybrid was reported, and this compound was used as a sensor for detection of H 2 S in living cells and in zebrafish, showing high selectivity . Furthermore, some very recent papers have reported the synthesis of novel julolidine derivatives and their use as sensors for solar cells, and as fluorescent probe for bioimaging cysteine in living cells have also been reported , . The interesting physical‐chemical properties of these molecules and their versatility for the application in several areas of research and technological development will certainly continue to stimulate the synthesis of new structures as well as the development of new approaches for the synthesis of these compounds.…”

Julolidines constitute a class of N‐heterocycle compounds which have in common the 2,3,6,7‐tetrahydro‐1H,5H‐benzo[1,2]quinolizine ring. Due mainly to its fluorescence properties, such structures have shown potential application in a range of scientific and technological areas and have attracted attention of a great variety of research groups. For example, julolidines have been used for detection of ions and volatile compounds in environmental and biological samples, to the construction of dye‐sensitized solar cells, photoconductive materials and as fluorescent sensors for bioimaging. This review summarizes the strategies reported to the synthesis of the julolidine ring and the principal modifications for obtaining more complex julolidine derivatives with improved fluorescence properties of these compounds. In this context, aldol condensation, olefination, imine synthesis, and cross‐coupling reactions have been extensively explored and discussed. Examples of applications, which illustrate the great potential of such structures, will also be briefly presented.

“…Avhad et al 74 synthesized a dye with CZ donor, rhodanine‐3‐acetic acid acceptor, methoxy auxiliary donor ( 21 ) and, for comparison, donors like TPA and julolidine based dyes were also synthesized ( 19 and 20 , respectively). At a set open‐circuit voltage (V OC ), the lifespan of the electron decreases in the sequence of donors: julolidine < diphenylamine < CZ which is in the sequence of rising V OC .…”

Summary In the present context of increasing population, renewable and sustainable energy alternatives are very much essential to satisfy the necessities of the world. To satisfy this growing demand, scientists are prioritizing the production of cost‐effective and high‐performance clean energy appliances. Dye‐sensitized solar cells (DSSCs) are one such material that is at the forefront of modern solar cell technologies. Being one of the main components of DSSCs, metal‐free organic dyes play a crucial role in light processing and electron injection. In recent times, carbazole (CZ)‐, triphenylamine (TPA)‐, and phenothiazine (PTZ)‐based derivatives have been identified as suitable alternatives to Ru(II) polypyridyl complexes because they are easy to synthesize and exhibit excellent thermal and electronic properties. This review focuses largely on the latest developments in the use of monoanchored and multianchored CZ, TPA, and PTZ scaffolds for DSSC applications and focuses especially on the correlation between molecular design and photovoltaic performance. The physical properties of devices can be adjusted through the sensitizer's strategic design that helps to improve the performance of the devices. We tabulated the photovoltaic parameters corresponding to all dyes presented in this review. Also, applications of additives are presented after the systematic review on CZ‐, TPA‐, and PTZ‐based dyes.

“…A sandwich compound of dicyclopentadienyl iron, Fe(C 5 H 5 ) 2 possess interesting redox properties as the iron core of Fe is capable to exist in both Fe 2+ or Fe 3+ which allowed extensive beneficial applications in energy production, electronic devices and microbiological research [14][15][16][17][18][19]. Ferrocenyl chalcone (Fig 1B) is a very electron rich compound exhibits a good electronic communication of ICT between the donor and acceptor parts.…”

Two organometallic compounds known as ( E )-1-ferrocenyl-(3-fluorophenyl)prop-2-en-1-one ( Fc1 ) and ( E )-1-ferrocenyl-(3-fluoro-4-methoxyphenyl)prop-2-en-1-one ( Fc2 ) are designed and synthesized for application in dye-sensitized solar cell (DSSC) based on a donor-π-acceptor (D-π-A) architecture. By strategically introducing a methoxy group into the acceptor side of the compound, Fc2 which has adopted a D-π-A-AD structure are compared with the basic D-π-A structure of Fc1 . Both compounds were characterized by utilizing the IR, NMR and UV-Vis methods. Target compounds were further investigated by X-ray analysis and studied computationally using Density Functional Theory (DFT) and Time-Dependent DFT (TD-DFT) approaches to explore their potential performances in DSSCs. An additional methoxy group has been proven in enhancing intramolecular charge transfer (ICT) by improving the planarity of Fc2 backbone. This good electronic communication leads to higher HOMO energy level, larger dipole moment and better short-circuit current density (J sc ) values. Eventually, the presence of methoxy group in Fc2 has improved the conversion efficiency as in comparison to Fc1 under the same conditions.
