Room temperature luminescence of 1,N-etheno-2-aminopurine in poly (vinyl alcohol) films.

We studied spectral properties of 1,N-etheno-2-aminopurine after immobilization in poly (vinyl alcohol) films. The absorption spectrum of 1,N-ε2APu consists of two peaks centered at 300 and 370 nm, and the fluorescence spectrum has maximum at about 460 nm. The fluorescence quantum efficiency is 62%.
