中文摘要 | 可錄一次式光碟片(Compact Disk-Recording once, CD-R)與傳統光碟片(Compact Disk, CD)最大的不同點在於CD-R有一層紀錄用色素層可以以雷射光燒錄成光碟片所需要之數位訊號,而紀錄層用的染料直接影響到CD-R的品質好壞,研究適用且品質優良的儲存媒體用染料成為電子特用品化學家的一大挑戰;而隨著CD-R的染料技術逐漸成熟,發展下一代儲存媒體用染料,成為可錄式碟片廠家在將來競爭的一大要素;由於儲存空間的需求,高密度儲存媒體(Digital Versatile Disk-Recording Once, DVD-R)可能迅速取代CD-R成為下一代儲存媒體主力產品;而本研究即是針對儲存媒體用染料中的花青(cyanine)染料,改變分子上的取代基作一系列研究,並可配合各家碟片廠家之需求,合出較符合其光特性、耐勢性及吸收波長的花青染料。 |
英文摘要 | The major difference between the compact disk (CD) and the compact disk recording-once (CD-R) is the recording layer on the CD-R. The major component of the recording layer is the laser dye, which can absorb the laser light to change reflective coefficient forming the digital signal source of CDs, the pits and the lands. The characters of the laser dye affect the quality of the CD-R directly. It is a good challenge for synthetic chemist to research good laser dyes for recording medium. For the recording medium producing companies, the technology for syntheses of the good laser dyes for CD-R is mature already. To develop new laser dyes for next generation product DVD-R, digital versatile disk-recording once, will be a core technology for these companies. This research involves organic synthesis of cyanine type laser dyes that may be used for the DVD-R. The discussion on the characteristics of synthetic cyanine dyes with different functional groups is also included. |
