Description
本発明は、シラフルオレン誘導体の製造方法に関する。 The present invention relates to a method for producing a silafluorene derivative.
近年、テレビ、携帯電話等における表示装置として、低消費電力かつ軽量な表示装置が求められている。有機エレクトロルミネッセンス(以下、エレクトロルミネッセンスをELと略記することにする)素子は、電極の間に有機EL素材を挟むだけという非常に単純な構造を持つ自発光素子であり、こうした要求を満たす素材として幅広い分野での利用が期待されている。 In recent years, low power consumption and lightweight display devices have been demanded as display devices for televisions, mobile phones and the like. An organic electroluminescence element (hereinafter abbreviated as EL) is a self-luminous element having a very simple structure in which an organic EL material is simply sandwiched between electrodes. Expected to be used in a wide range of fields.
