摘要：
A kind of carbazole-based covalent triazine framework (CTF-Cz) has been synthesized from a carbazole derivative. The porous polymer can efficiently adsorb probe molecules due to the strong intermolecular interactions caused by the polar triazine moiety. CTF-Cz directly serves as the surface-enhanced Raman scattering substrate without any post proceeding techniques. The enhancement factor of CTF-Cz is similar to 10(5) for detecting rhodamine 6G (R6G). The lowest unoccupied molecular orbital energy level of CTF-Cz (-3.93 eV) is much lower than that of R6G, which is in favor of the charge transfer from R6G to CTF-Cz for illumination under a 532 nm laser, which is proved by time resolved photoluminescence spectra. The efficient charge transfer induced by the strong intermolecular pi-pi interactions and large molecular-orbital delocalization contribute to the enhanced Raman signals of R6G on CTF-Cz.
