Push-pull purine derivatives are attractive as sensors and reporters for biological applications. Recently the fluorescent purines as materials for electronic devices have also been developed. 1 Different combinations of electron donor and acceptor substituents allow fluorescence emission tuning in the range of 350-450 nm, making the purines good candidates for the construction of OLED devices. 1 Earlier we have reported that N6-substituted 2-triazolyl-adenine nucleosides exhibit strong fluorescence with emission maxima around 400 nm and quantum yields up to 53%. 2 The aim of this research was to synthesize 9-alkyl purines with electron donor at C(6) and 4- substituted 1,2,3-triazol-1 -yl group as acceptor at C(2) and investigate their fluorescence properties.
