    • Single crystals of 2a were obtained by recrystallization from hexane. Diffraction data were collected with a Rigaku AFC-8 CCD diffractometer using multi-layer confocal-mirror monochromated and focused MoKα radiation (λ, 0.71073 Å) at 90 K. The structure was solved by direct methods using the program SIR-2004 [Burla, M. C, Caliandro, R, Camalli, M, Carrozzini, B, Cascarano, G. L, De Caro, L, Giacovazzo, C, Polidori, G, Spagna, R, J. Appl. Crystallogr. 2005, 38, 381-388, Refinements were carried out by a least-squares method on F2 using the program shelxl-97 [Sheldrick, G. M. Acta Crystallogr. Sect.

    • The authors thank a referee who pointed out that the data of excited state lifetime will increase the impact of this work. We unfortunately cannot obtain the data soon, because we do not have an instrument for fluorescence lifetime measurement. We would like to measure the data for preparing a full paper.
