Özet:

 

The spectral-luminescent properties and electrochemistry of  the N,N'-bis-n-butyl derivative of naphthalene diimide were studied.   The main photophysical parameters (quantum yield, rate constants of  fluorescence and of non-radiative deactivation and fluorescence  lifetime) were determined.    The LUMO value (-3.51 eV) was determined by cyclic voltammetry.  The  N,N'-bis-n-butyl derivative of naphthalene diimide (BBND) shows 2  reversible reduction steps (-1.19 V and -1.75 V vs.  Ferrocene) in  chloroform.    Quenching the fluorescence emissions of aromatic donor molecules in  acetonitrile revealed the electron acceptor ability of the studied  naphthalene diimide derivative.    It has been found that, in contrast to perylene diimide derivatives,  which form p-electron donor-acceptor complexes with aromatic  donor molecules of naphthalene, phenanthrene, pyrene and perylene,  BBND does not form p-electron-donor acceptor complexes with  aromatic donor molecules.
