Because metal naphthalocyanine has larger conjugate system than MPc does, and its main absorption peaks shift to 750～850nm region, which is optimal for light penetrating tissue. That would endow MNc with strong photodynamic effect and weak phototoxic by-effect. And it would be a new and practical PDT photosensitizer.

本文考虑到比金属酞菁具有更大共轭体系的金属萘酞菁配合物（Metal Naphthalocyanines，简称MNc）其电子吸收光谱Q带主吸收峰比金属酞菁红移100—150nm，达到750—850nm范围，位于人体最佳透射波段的近红外区，这既可使之具有较高的激发效率和较强的肿瘤细胞杀伤效应，又可更进一步降低可见光引起的光毒副作用，可望成为新一类有应用前景的抗癌光敏剂。

To achieve this, the or each steam generator pipe (22, 50, 60) has a respective downpipe section (34, 52, 62, 64), which is approximately vertical and through which the flow medium can flow downwards and a respective riser pipe section (36, 54, 66, 68) connected downstream of the downpipe on the flow medium side, which is approximately vertical and through which the flow medium can flow upwards.

The results show that DCRP is indeed a excellent flame retardant. The material can reach the UL-94-V-0 level through choice different synergist. Many alternative synergists to antimony oxide are available for use. Zine and iron compounds are often used in place of the standard antimony oxide because of their lower cost and special properties. Additionally, synergist mixtures are also useful in obtaining specific properties.
