Abstract

본 발명은 광기록 매체에 있어서, 하기 일빈식(Ⅰ)로 표시되는 시아닌계 색소를 TCNQ나 그 유도체들과 전하이동착물(시아닌-TCNQ)을 만들어 반도체 레이저(780-830㎚)에서 기록가능한 물질로 적용함을 특징으로 하는 전하이동착물을 이용한 광기록 매체에 관한 것으로, TCNQ계 물질들의 광기록 특성을 이용하여 시아닌계 색소들이 TCNQ와 전하이동착물을 형성함으로써, 광기록매체에 레이저를 조사하면 기록층의 시아닌-TCNQ가 레이저를 흡수하여 용융되거나 분해되어 기록이 되며, 기록레이저보다 적은 파워로 기록부와 미기록부의 반사율 차리를 읽어냄으로써 재생된다.
상기 식에서 R은 헤테로아로마틱 잔기 R'는 알킬기 n은 2이상의 양의 정수이다.
