项目摘要

Carbon black (CB) is an excellent black pigment on the market. CB is low-cost and extremely light and heat stable, as also characterized by a high hiding power. Because of this, CB is regarded as the perfect black pigment. However, it has recently been pointed out that CB includes benzpyrene and other impurities that induce cancers, because. CB is usually prepared by incomplete decomposition of hydrocarbons at elevated temperatures. There is also another issue concerning the inherent nature of the electrical conductivity of CB. An electrically-insulating black pigment is appropriate for LCD (liquid crystal display) color filter applications. For these reason, an attempt was made to develop a black pigment that is environmentally friendly and electrically insulating. Our idea is to realize a black pigment by two absorption bands which cover the whole visible region. The former band is due to individual molecules while the latter arises from intermolecular interactions between transition dipoles. We have carried out a series of investigations on perylene and its related compounds on the basis of the crystal structure and intermolecular interactions. Finally, we have achieved a black pigment with benzoimidazo perylene derivatives. The key technologies were to utilize interactions between transition dipoles and calcination at high temperatures.

炭黑（CB）是市场上一种性能优良的黑色颜料。CB成本低，对光和热非常稳定，还具有高遮盖力的特征。正因为如此，CB被认为是完美的黑色颜料。然而，最近有人指出，CB包括苯并芘和其他诱发癌症的杂质，因为。CB通常是通过烃在高温下的不完全分解来制备的。还有另一个问题是关于CB的导电性的固有性质。电绝缘黑色颜料适用于LCD（液晶显示器）滤色器应用。出于这些原因，尝试开发环境友好且电绝缘的黑色颜料。我们的想法是通过覆盖整个可见光区的两个吸收带来实现黑色颜料。前一个带是由于个别分子，而后者产生的过渡偶极子之间的分子间相互作用。我们对苝及其相关化合物的晶体结构和分子间相互作用进行了一系列的研究。最后，我们用苯并咪唑并苝衍生物合成了一种黑色颜料。关键技术是利用过渡偶极子之间的相互作用和高温煅烧。
