実施例1〜5および比較例1〜2で得た化合物(1)〜(5)および(11)〜(12)について、296Kおよび77Kにおける固体発光量子収率φ(%)を測定した。具体的には、化合物(1)〜(5)および(11)〜(12)の結晶状態(粉末)における発光量子収率を、絶対法によりそれぞれ求めた。化合物(1)〜(5)は、加熱して調製したn−ヘキサン/ベンゼン(体積比は、n−ヘキセン/ベンゼン=6/4)の溶液を室温で放冷することにより結晶化した結晶を用いた。化合物(11)および(12)は、加熱して調製した酢酸エチルの溶液を室温で放冷することにより結晶化した結晶を用いた。測定方法は以下の通りである。
測定の際、酸素の影響を除くため、全てのサンプルは、石英セル中に結晶(化合物(1)〜(5)および(11)〜(12))をそのまま封入して、アルゴン雰囲気下で測定した。さらに、低温(77K)での測定は、石英製デュワーを用いて、結晶を封入した上記石英セルを液体窒素で冷やしながら測定した。全ての発光スペクトルは、標準光源を利用することにより補正を行った。励起光として420nmの波長の光を用いた。内部量子収率の算出には、固体量子効率計算プログラム(日本分光株式会社製)を用いた。また、各有機白金錯体が発する光の発光極大波長も、併せて測定した。測定結果を表1に示す。
