AbstractA rapid access to a series of N-heteroarene fluorophores has been developed on the basis of the palladium-catalyzed direct oxidative C–H/C–H coupling of imidazo[1,2-a]pyridines with thiophenes/furans. The photophysical properties–structure relationship was systematically investigated. The resulting N-heteroarene fluorophores present color-tunable emissions (λem: 431–507 nm in CH2Cl2) and high fluorescence quantum yields (up to 91% in CH2Cl2).

AbstractSulfur-containing functional π-conjugated cores play key roles in materials science, mostly due to their unique electrochemical and photophysical properties. Among these, the excellent electron donor tetrathiafulvalene (TTF) has occupied a central position since the emergence of organic electronics. Peripheral C–H modification of this highly useful sulfur-containing motif has resulted in the efficient creation of new molecules that expand the applications of TTFs. This Short Review begins with the development of the palladium-catalyzed direct C–H arylation of TTF. Subsequently, it summarizes the applications of this efficient C–H transformation for the straightforward synthesis of useful TTF derivatives that are employed in a variety of research fields, demonstrating that the development of a new reaction can have a significant impact on chemical science.1 Introduction2 Development of the Palladium-Catalyzed Direct C–H Arylation of TTF3 Synthesis of TTF-Based Tetrabenzoic Acid and Tetrapyridine for MOFs4 Synthesis of TTF-Based Tetrabenzaldehyde and Tetraaniline for COFs5 Tetraarylation of TTFAQ6 Synthesis of Multistage-Redox TTF Derivatives7 Miscellaneous Examples8 Conclusions

Palladium Catalyzed

A series of BN-phenanthrenes with substituents of a diverse nature have been synthesized by palladium-catalyzed cross-coupling reactions of a common chloro-substituted precursor, which was made from readily available materials in only four steps. Evaluation of the photophysical properties of the prepared compounds unveiled an impressive effect of the presence of alkynyl substituents on the fluorescence quantum yield, which improved from 0.01 in the parent compound to up to 0.65 in derivatives containing a triple bond.
