英文摘要	A star-shaped cyclometalated triruthenium complex 2(PF6)(n) (n = 3 and 4) with a triarylamine core was synthesized, which functions as a molecular switch with five well-separated redox states in both solution and film states. The single-crystal X-ray structure of 2(PF6)(3) is presented. This complex displays four consecutive one-electron redox waves at + 0.082, + 0.31, + 0.74, and + 1.07 V vs Ag/AgCl. In each redox state, it shows significantly different NIR absorptions with lambda(max) of 1590 nm for 2(4+), 1400 nm for 2(5+), 1060 nm for 2(6+), and 740 nm for 2(7+), respectively. Complex 2(4+) shows a single-line EPR signal at g = 2.060, while other redox states are all EPR inactive. The spin density distributions and NIR absorptions in different redox states were rationalized by DFT and TDDFT calculations. A vinyl-substituted triruthenium analogous 3(PF6)(4) was prepared, which was successfully polymerized on ITO glass electrode surfaces by reductive electropolymerization. The obtained poly-3(n+)/ITO film was characterized by FTIR, AFM, and SEM analysis. It shows four well-defined redox couples and reversible multistate NIR electrochromism. In particular, a contrast ratio (Delta T%) up to 63% was achieved at the optic telecommunication wavelength (1550 nm).
