Synthesis and Photophysical Study of N-Alkyl or N,N-Dialkyl Pyrene-1-carboxamide derivatives

Abstract

In this study, We synthesized secondary N-alkyl- and tertiary N,N-dialkyl-pyrene-1-carboxamide derivatives, and investigated their photoluminescent properties. This study shows that N-alkyl carboxamide group makes pyrene-chromophore highly emissive. N,N-dialkyl carboxamide group, however, makes dye weak but it emit in viscous media. This result indicate that N,N-dialkyl-pyrene-1-carboxamide derivatives have the potential of application environmentally-responsive fluorescent materials.
