Abstract
一种光信息记录介质，具有一记录层，且受到波长为620nm到690nm的激光束影响而进行记录与读取。该记录层包括至少一种非对称三次甲基花青染料(trimethine－cyanine dye)，其具有如下列分子式[1]、[2]、[3]或[4]所示的结构，其中，“EWG”表示任一吸电子取代基，例如硝基或氰基。
Description
技术领域
本发明涉及一种光信息记录介质，尤其涉及一种包含至少一种具有吸电子取代基(electron-withdrawing substituted group)的非对称三次甲基花青染料(trimethine-cyanine dye)的记录层的光信息记录介质。
背景技术
在现今科技中，光信息记录介质具有激光照射后记录一次的功能。就单次记录型(write once)光盘(CD-R)信息记录介质而言，包含一有机染料的记录层，反射层(reflection layer)及保护层(protective layer)依次于一透明基板上形成薄片。其中，当波长介于780nm及830nm之间的激光照射于光盘的记录层时，激光将致使记录层的染料产生分解或变形作用，以在光盘上形成记录信息。利用记录区域及未记录区域之间的反射差异，信息通常可以借助上述的激光再生。
具有较短波长的激光通常具有缩小的光点(reduced light spot)，因此，有些研究已开发出可让波长介于620nm及690nm之间的激光束进行记录及再生的光盘，用以增加记录密度。其中，可记录数字影音光盘(recorded digital versatile disc，DVD-R)具有高密度的记录及读取功能，且DVD-R正被开发成为下一代的新记录介质。由于进行DVD-R的记录及再生的激光波长与进行CD-R的记录及再生的激光波长有所不同，这使得被选择作为CD-R的记录层材料将不能适用于DVD-R。因此，必须发展新的DVD-R的记录材料。
三次甲基系花青染料是大众所喜爱的DVD-R记录层，美国专利No.5976658及No.6291045中描述了三次甲基系花青染料的使用，该染料具有对称或非对称的吲哚结构。美国专利No.6291045中使用了可见-紫外光谱仪的方式，公开了记录层可见-紫外光谱的次波峰相对于主波峰的吸光度比率小于0.8的结果。并且，当DVD-R刻录机的激光波长介于635nm到650nm之间时，对染料物质的选择应该更要谨慎注意。因为当激光束的波长变长时，原来适用于激光束写入波长为635nm下进行写入的记录材料，将不适用于激光束写入波长为650nm的情况。所以，须将记录层材料在溶液状态下的可见-紫外光光谱的最大吸收波长调整为575nm至590nm的范围内。
发明内容

A：合成吸电子取代基的非对称三次甲基花青染料
本发明所使用的非对称染料是具有吸电子取代基的花青素染料，其合成方式可参考J.Org.Chem.1995，60，2411及美国专利No.630647785中所提及的不同方法，如化学式1、2及3所示。但在实际合成的过程中，在大量合成中，会有一些执行上的困难。
举例而言，“EWG”表示分子式[1]化合物中的硝基，而“R3”及“Y”皆表示为分子式[1]化合物中的氢原子。在合成分子式[11]化合物的时候，因为分子式[10]化合物的活性较低，而且反应需在密封管中进行，所以，分子式[11]化合物难以由反应式1所表示的合成方式获得，且产率相当低。
反应式1
而且，即使获得了分子式[11]的化合物，反应在醋酸酐溶剂的回流(refluxing)条件下也并不进行反应式2中路径1的反应，而是进行路径2的反应并得到分子式[13]的化合物。
反应式2
在反应式3所示的反应中，虽然可顺利获得分子式[1]的化合物，但是产率却相当低，不符合经济效益，而且在合成的处理方式上也相当费时费力。
反应式3
所以，我们设计了一种修正的反应方法如反应式4，反应可在大气压力下进行，不需通氮气或其他惰性气体，却可得到高产率的分子式[1]的化合物。在反应式4的反应中，分子式[15]及分子式[11]的化合物可通过一般熟知的烷基化反应及硝化反应的反应条件获得较高的产率。将分子式[11]的化合物与N，N-二苯基甲酰胺溶于醇类溶剂中，加热至回流，回温后可获得较佳品质及产率的分子式[16]的结晶化合物。最后，将分子式[16]及[13]的化合物与有机碱在室温下搅拌，经过一般的化学处理程序之后，获得了高产率的分子式[1]的化合物。
反应式4
其中，借助反应式4的合成方法，可以合成分子式[1]、[2]、[3]及[4]的化合物种类，如下列多个表中所示：化合物编号 EWG R1 R2 R3 X Y1-1 CN CH3 CH3 H ClO1 H1-2 CN C2H5 CH3 H ClO1 H1-3 CN C3H7 CH3 H ClO1 H1-4 CN C1H9 CH3 H ClO1 H1-5 CN C8H17 CH3 H ClO1 H1-6 CN CH3 CH3 H PF6 H1-7 CN C2H5 CH3 H PF6 H1-8 CN C3H7 CH3 H PF6 H1-9 CN C1H9 CH3 H PF6 H1-10 CN C8H17 CH3 H SF6 H1-11 CN CH3 CH3 H SF6 H1-12 CN C2H5 CH3 H SF6 H1-13 CN C3H7 CH3 H SF6 H1-14 CN C1H9 CH3 H SF6 H1-15 CN C8H17 C1H9 H SF6 Me1-16 CN C8H17 C1H9 H SF6 Et1-17 NO2 CH3 CH3 H ClO1 H1-18 NO2 C2H5 C2H5 H ClO1 H1-19 NO2 C3H7 C4H9 H ClO1 H1-20 NO2 C4H9 CH3 H ClO1 H1-21 NO2 C3H7 C1H9 H PF6 H1-22 NO2 C3H7 C1H9 H SF6 H1-23 NO2 C3H7 C1H9 H BF1 H1-24 NO2 C3H7 C1H9 H CH3SO3H

具体实施方式
以下，本发明将举实施例以说明本发明的方法、特征及优点，但并不限定本发明的范围，本发明的范围应以权利要求书为准。
染料合成步骤
第一，先合成N-丙基-2-(2-苯胺基乙烯基)-3，3-二甲基-5-硝基吲哚氯酸鎓盐[16-1]，
分别将23g的1-丙基-2，3，3三甲基-5硝基吲哚氯酸鎓盐、20g的N，N-二苯基甲酰胺及70ml的1-辛醇置于500ml的圆底瓶内，加热回流24小时。回到室温之后，可得到橘棕色结晶的分子式[16-1]的化合物。其氢核磁共振的结果如下：1H NMR(300MHz，DMSO-d6)δ1.04(t，J＝7.4Hz，3H)，1.85(s，6H)，4.15(t，J＝7.4Hz，2H)，6.30(d，J＝12.1Hz，1H)，7.40(t，J＝7.2Hz，1H)，7.53-7.66(m，4H)，7.79(d，J＝8.85 Hz，1H)，8.40(dd，J＝12.1，2.3Hz，1H)，8.68(d，J＝2.3Hz，1H)及8.88(d，J＝12.1Hz，1H)。

除了本实施例以分子式[18]的染料替换实施例1的染料物质外，本实施例依照实施例1的方法来制备光盘。本实施例运用实施例1所使用的仪器测量记录层的光学参数，且所测量的结果皆记载于表1中。
在本对照例中，所获得的记录光盘无法有效地被具有写入波长为650nm的DVD-R机器进行信息记录。
综上所述，当记录机器所示用的激光光束的波长为650nm时，实施例1、2及3所制备的光盘的记录层比对照例1及2所制备的光盘的记录层具有更好的表现。其中，实施例1、2及3所制备的光盘的记录层只包括一种三次甲基花青染料并具有吸电子基的非对称取代结构，而对照例1及2所制备的光盘的记录层则包括对称结构的三次甲基花青染料。

实施例4
首先，提供一透明基板，基板是一由聚碳酸酯所构成的光盘，而此光盘具有一条螺纹状的沟槽且其轨道间距为0.74μm，光盘的外径是为120mm，且厚度为O.6mm。
接着，将3.0g的分子式[1-21]的化合物及0.6g的衍生于分子式[5]的分子式[19]的化合物溶解于50ml 2，2，3，3-四氟-1-丙醇中，于室温下搅拌5小时，再经过0.2μm的聚四氟乙烯薄膜过滤后，配制成染料溶液。
利用旋转涂布的方式，设定转速为3000rpm，在基板上涂布上一层染料，然后再70℃下烘干20分钟，形成厚度为100nm的记录层。
然后，在记录层之上以溅镀的方式镀上金或银的反射层，其中，用氩气当作溅镀时所需的气体，而溅镀所需的电功率为1.5kw，且溅镀压力为1.0×10-2torr。
然后在反射层上，涂布一紫外线固化型树脂(日本Chemicals，Inc.的No.575)，照射紫外光将树脂固化，形成保护层。再通过粘合剂，将制成的盘片与另一不具有沟槽的单面基板贴合，所述另一基板是依上述步骤制成并放置于具有紫外线烘干树脂的基板上。当介于两基板间的树脂通过旋转的方式被驱散时，本发明再以紫外线照射的方式，将紫外线固化型树脂固化，形成厚度为25μm及直径为32-120mm的贴合区域的方式，从而获得一多层式光盘。
最后，本发明将借由DVD-R/RW A03，PIONEER5的记录器以进行光盘的记录试验，而DVDT-R，DVD-R/RW TESTER，DVDT-R 650及EXPERT MAGNETICSCo.，Ltd.分别用来测量反射率、推挽值、振动及调制度，其结果皆记载于表2中。
实施例5
除了本实施例以2.0g的分子式[1-22]的化合物及0.4g的衍生于分子式[5]的分子式[19]的化合物所组成的混合物替换实施例4的染料物质外，本实施例依照实施例4的方法制备记录光盘。本实施例运用实施例4所使用的仪器测量记录层的光学参数，且测量的结果皆记载于表2中。
实施例6
除了本实施例以2.0g的分子式[1-23]的化合物及0.9g衍生于分子式[5]化合物的分子式[19]的化合物所组成的混合物替换实施例4的染料物质外，本实施例依照实施例4的方法制备记录光盘。本实施例运用实施例4所使用的仪器测量记录层的光学参数，且测量的结果皆记载于表2中。
实施例7
除了本实施例以2.0g的分子式[1-16]的化合物及0.2g衍生于分子式[5]化合物的分子式[19]的化合物所组成的混合物替换实施例4的染料物质外，本实施例依照实施例4方法制备记录光盘。本实施例运用实施例4使用的仪器测量记录层的光学参数，且测量的结果皆记载于表2。
对照例3
除了本实施例以2.0g的分子式[20]的化合物及0.2g的衍生于分子式[5]化合物的分子式[19]的化合物所组成的混合物替换实施例4的染料物质外，本实施例依照实施例4的方法制备记录光盘。本实施例运用实施例4所使用的仪器测量记录层的光学参数，且测量的结果皆记载于表2中。
在本对照例中，所获得的记录光盘无法有效地被具有写入波长为650nm的DCD-R机器进行信息记录。然而，记录光盘可被具有写入波长为635nm的DVD-R机器进行信息记录。
对照例4
除了本对照例以2.0g的分子式[21]的化合物及0.2g的衍生于分子式[5]化合物的分子式[19]的化合物所组成的混合物替换实施例4的染料物质外，本实施例依照实施例4的方法制备记录光盘。本实施例运用实施例4所使用的仪器测量记录层的光学参数，且测量的结果皆记载于表2中。
在本对照例中，所获得的记录光盘无法有效地被具有写入波长为650nm的DVD-R机器进行信息记录。
对照例5
除了本实施例以2.0g的分子式[22]的化合物及0.2g的衍生于分子式[5]化合物的分子式[19]的化合物所组成的混合物替换实施例4的染料物质外，本实施例依照实施例4的方法制备记录光盘。本实施例运用实施例4所使用的仪器测量记录层的光学参数，且测量的结果皆记载于表2中。
在本对照例中，所获得的记录光盘无法有效地被具有写入波长为650nm的DVD-R机器进行信息记录。
综上所述，当记录器使用写入波长为650nm的激光光束时，实施例4至实施例7的结果皆令人满意。在实施例4至实施例7中，记录层包括两种三次甲基花青染料，而染料物质之一必须具有吸电子基的非对称取代结构。假设该染料物质被更改为具有推电子取代基的花青染料，或具有吸电子基的对称取代结构的花青色素染料时，则相对应光盘的记录结果将会产生失误现象，其中，更改后染料的取代基为例如对照例4的氢、对照例5的氯，以及对照例6的甲基。
本发明上述实施例所揭露的光信息记录介质，使用了具有吸电子基的非对称取代结构的三次甲基花青染料物质，从而获得了高反射率、高推挽值、低振动及高调制度的特性。振动越低，光盘的热将不易累积，且高调制度结合低振动意味着再生的敏感性很好。当以波长为650nm的激光进行记录程序时，可以明显地发现具有吸电子基的非对称取代结构的染料物质很大程度上改进了记录性质。
综上所述，虽然本发明已揭示了如上的较佳实施例，然而并不限定本发明的范围，任何熟悉此项技术者，在不脱离本发明的精神和范围内，都可作相应的变更或润饰，因此本发明的保护范围应当以权利要求书的界定为准。
