N2  - Two novel V-shaped push-pull systems based on a pyrimidine acceptor have been designed and investigated.  Low-temperature measurements of the fluorescence and delayed luminescence spectra demonstrated that the  emission bands of the compounds have a charge-transfer character.  Despite the fact that compounds in thermal vacuum deposition films have a low fluorescence quantum yield, OLED devices based on them show high efficiency, which can be associated with the emission mechanism through delayed fluorescence. It is found that photoproducts, obtaining upon exposure to UV-irradiation of fluorophores in chloroform solution, exhibit laser activity in the red region of the spectrum
