Could anyone suggest me what is effect of electron donating and withdrawing group on fluorecence emission or intersystem crosssing.
Thank you
It depends from system to system. I have seen in case of single component system like Schiff bases EWG systems are more emissive where as in 2 component systems like in cocrystal EDG group are emissive and quenching occurs in case of EDG.
thank you so much for your suggestion
