Abstract

-alkyl-1

3-triazoles and

-alkyl-1

3-triazoles were prepared

and their photophysical properties were investigated. Both type of 1

3-triazoles have strong photo absorptions at near 250 nm

however only

-alkyl-1

3-triazoles give fluorescence emissions. From the screen of the photophysical properties of different substituted

-alkyl-1

3-triazoles at

-or

-sites

it is found that

-alkyl-1

3-triazoles bearing rich electron benzyl group at

-site or poor electron phenyl group in

-site have the strong fluorescent intensity

and the quantum yields are up to 79% with 300-440 nm of fluorescent emissions and 49-70 nm of Stokes shifts. The photophysical properties of

-alkyl-1

3-triazoles show their potent application in the development of fluorescent materieals.
