“…The range of D-A chromophores with hydrazinylidene acceptors 205 was expanded by the action of organolithium reagents on cyclic diazo compounds 206, which made it possible to introduce thiophene fragments MeOH, reflux into the chromophore to create planar molecules (Scheme 78) [136].…”

The review summarizes the literature data on the synthesis, structure, reactivity, and rearrangements of pentacarboxycyclopentadienes and their derivatives. Their potential for creating new chiral organic catalysts for enantioselective Diels-Alder reactions, cationic polymerization of vinyl ethers, enantioselective protonation of silylenol ethers, aminomethylation, and other processes is described, and aspects of their use as effective carriers of functional groups, new ligand systems for the synthesis of metal complexes and donor-π-acceptor chromophores for organic photovoltaics are considered.

Organic fluorophores are indispensable tools in cells, tissue and in vivo imaging, and have enabled much progress in the wide range of biological and biomedical fields. However, many available dyes suffer from insufficient performances, such as short absorption and emission wavelength, low brightness, poor stability, small Stokes shift, and unsuitable permeability, restricting their application in advanced imaging technology and complex imaging. Over the past two decades, many efforts have been made to improve these performances of fluorophores. Starting with the luminescence principle of fluorophores, this review clarifies the mechanisms of the insufficient performance for traditional fluorophores to a certain extent, systematically summarizes the modified approaches of optimizing properties, highlights the typical applications of the improved fluorophores in imaging and sensing, and indicates existing problems and challenges in this area. This progress not only proves the significance of improving fluorophores properties, but also provide a theoretical guidance for the development of high‐performance fluorophores.
