Abstract

In this paper, four green luminescent gels were successfully formed in dimethyl sulfoxide as solvents. The gels are prepared by self-assembly of urea derivatives gelator N,N′-dioctadecylurea 1 and N-octadecylurea 2 in the presence of two terbium complexes. Very interestingly, the analysis of the peak intensities as function of temperature during heating treatments could be described by two linear equations at two stages. The best fit results were composed of two independent decay processes.
