Molbank, Vol. 2018, Article M1024: Purine-Furan and Purine-Thiophene Conjugates (Molbank)

Furyl and thienyl moieties were introduced into a purine structure to elevate its fluorescence properties, while a trityl group was used to increase the amorphous properties of the purine compounds. The title compounds were prepared by a sequence involving a Mitsunobu, a SNAr and a Suzuki-Miyaura reaction and their photophysical properties were studied. Quantum yields in the solution reached up to 88% but only up to 5% in the thin layer.
