さらに本発明では、上述した本発明の塗布用組成物に対し、さらに芳香族化合物を添加してもよい。この時添加する芳香族化合物としては、本発明における機能性の観点から、有機色素または有機発光体または有機半導体であることが好ましい。
また、本発明を実施することで、本発明の有機無機ハイブリッド材料を合成するための原料(塗布用組成物)を提供することができる。さらに、その塗布用組成物を用いて本発明の有機無機ハイブリッド材料を製造する手法を提供することができる。
本実施の形態では、金属酸化物マトリクスに直接結合した有機基を有し、単なる金属酸化物とはことなる機能を発現することができる材料を提供することを目的とし、合成された有機無機ハイブリッド材料について説明する。本発明の有機無機ハイブリッド材料は、図1で示したように、少なくとも機能性キレート剤と金属酸化物マトリクスを有している。
以下では、実施の形態1に示した有機無機ハイブリッド材料を合成するための塗布用組成物について説明する。本発明の塗布用組成物は、少なくとも金属アルコキシドおよび/または金属塩、機能性キレート剤、および有機溶媒を含んでいる。
本実施の形態3では、本発明の有機無機ハイブリッド材料を用いたキャリア注入型エレクトロルミネッセント素子の構成について、図6(a)を用いて説明する。図6(a)では基板を省略しているが、陽極601、陰極603のいずれの側に基板があっても良い。
本実施の形態4では、本発明の有機無機ハイブリッド材料を用いた真性エレクトロルミネッセント素子の構成について、図6(b)を用いて説明する。図6(b)では基板を省略しているが、第1電極611、第2電極613のいずれの側に基板があっても良い。
本比較例では、実施例1のゾルから8−キノリノールを除いた状態の従来のゾル(すなわち、金属アルコキシドとしてアルミニウム−sec−ブトキシドを、化学改質剤としてアセト酢酸エチルを、有機溶媒としてイソプロパノールを用いたゾル)を調製し、塗布・焼成を行った。
8−キノリノールを配位子として有する金属錯体(分子)であるトリス(8−キノリノラト)アルミニウム(略称:Alq3)が単にシリカ中に分散されている状態を作製するため、上記表2中に示した組成のゾルを調製した。エタノールおよび水の量は実施例4と同じとした。本比較例のゾルにおいては、Alq3の溶解性が悪く、完全な液状は得られなかった。
さらに比較のため、上記表2中に示した組成のゾル(すなわち、3価の金属であるアルミニウムに対して、配位子の数が飽和するよう、8−キノリノールを3等量加えたもの)を調製した。エタノールおよび水の量は実施例4と同じとした。
さらに、本実施例では、陽極は透明電極であり、陽極側から電界発光層で生じた光を出射させる構成としているが、本発明はこれに限定されることはなく、透過率を確保するために適した材料を選択することにより陰極側から光を出射させる構成とすることもできる。
