The direct Pd-catalyzed intramolecular rapidly with electron-deficient benzene ring, which, in hydroarylation of o-alkynyl biaryls proceeded in highly combination with a substantial isotope effect observed, stereoselective manner producing fluorenes 2, the products of 5-exo-dig cyclization, in excellent yields. The cascade intermolecular arylation, incorporated in this transformation, allowed for efficient

Even though the aggregation-induced emission phenomena have been described for diphenylbenzofulvenederivatives for about 15 years, their solid-state emission in films has not been previously studied. Hereby, their solid-state emission is characterized and the whitelightemission of a thin film made of mixture of the derivatives DPBFMe and DPMF(Me)2 is deciphered.
