Abstract：Based on the development of probes in recent years, the preparation of luminescent materials with better optical properties has become a hotspot of current chemical workers. This work is intended to prepare a new type of luminescent material with better optical performance to meet people’s daily life and medical demands. The complex of tetracynoethylene-1,10-phenanthroline was formed with tetracynoethylene (TCNE) and 1,10-phenanthroline (Phen) under specific conditions and characterized by UV-Vis spectrometry, Fluorescence spectrometry and Raman scattering spectrometry. Then the reaction mechanism was explored preliminarily. The absorption peaks of complex was compared with the absorption peaks of ligands. It showed that the absorption of complexes was due to the absorption of ligand 1,10-phenanthroline, indicating that tetracynoethylene and 1,10-phenanthroline formed stable complexes. At the same time, the fluorescence spectra were analyzed. It was found that the emission peak of the complex was similar to that of the ligand tetracynoethylene, and the fluorescence of the complex was believed to be derived from the π—π* electron transition of the ligand. It can be seen from the Raman spectra that the Raman intensity of the complex at 1 000~1 600 cm-1 was significantly enhanced compared with the Raman intensity of tetracynoethylene ligand. The resonant Raman scattering was strongly coupled at 1 000~1 600 cm-1, and these resonant Raman peaks were strongly enhanced due to the charge transfer between molecules. The results suggested that the ligand tetracynoethylene had coordinated successfully with ligand 1,10-Phenanthroline and the fluorescence intensity was significantly improved. At the same time, the absorption of complex mainly came from the ligands absorption. In the above study, the 1,10-Phenanthroline-tetracyanoethylene charge transfer complex was synthesized for the first time and its optical properties were studied. This study provided an experimental basis for the design and synthesis of complexes with superior luminescent properties, promoting the progress of the career of the optics and contributed the exploration and development of new nucleic acid probes.
