Here we report design and synthesis of fluorescent purine derivatives with amorphous properties and their potential applications in the OLED technology. For this purpose, we have introduced different five-membered heterocycles and piperidine at C6/C2 positions of purine and different amorphous groups at N9 position. We used boric acid derivatives to obtain furan-3-yl, thiophen-2- yl and thiophen-3-yl compounds and simple SNAr procedure for imidazolyl, 1,2,4-triazolyl and tetrazolyl compounds. All synthetic routes were elaborated from the 2,6-dichloropurine by varying sequences of Mitsunobu, SNAr, Suzuki and cyclization reactions. The final products were obtained with different regioselectivity in 74-86% yields.
