Measurement of XRD Spectra: X-ray powder patterns were re-
corded on a Rigaku RINT2500 instrument by using graphite-mo-
nochromated Cu-Kα radiation (40 kV, 80 mA). The spectra were
measured at room temperature between 3 and 35° in the 2θ scan
mode in steps of 0.02° and 3 °min–1.

Measurement of Solid-State CD and Absorption Spectra: The CD
and absorption spectra were recorded by using a Jasco J-800KCM
spectrophotometer. The solid-state samples were prepared accord-
ing to the standard procedure for obtaining glassy KBr matrices.[10]
Measurement of Solid-State Fluorescence Spectra: Solid-state fluo-
rescence spectra and the absolute photoluminescence quantum
yields were measured by using the Absolute PL Quantum Yield
Measurement System (C9920-02, HAMAMATSU PHOTONICS
K.K.) in air at room temperature. Excited wavelengths are 389 nm
for complex I and 408 nm for component molecule 3 were used.
