| Abstract: | A facile one-pot solvothermal route has been developed for the synthesis of tubular luminescent polymeric networks [(C3N3)2(NH)3]n, structurally related to the proposed g-C3N4. XRD patterns showed a characteristic 002 basal plane diffractions, indicating an interlayer d spacing of 3.23 Å. XPS spectra show that the C1s and N1s have a symmetric peak and an asymmetric peak at 288.10 and 399.00 eV, respectively. The bulk composition C6N8.9H4.5 determined by elemental analysis is comparable to the calculated value C6N9H3 for this proposed polymer. FTIR spectra indicated the presence of s-triazine ring, which was further supported by the luminescent and UV-vis absorption characteristics probably depending on π→π* electronic transition. The tubular structure has been studied by TEM, SAED, and HREM. |
