  Photosensitizer particle contrast agents are suitable for medical imaging and/or photodynamic therapy. The photosensitizer particle contrast agent has a shell and a core encased by the shell. The shell consists essentially of multiple photosensitizer conjugates. Each photosensitizer conjugate consists of a photosensitizer and at least one biodegradable polymer covalently bound to the photosensitizer. The core has an echogenic contrast-enhancing material loaded therein. The photosensitizer of at least one of the multiple photosensitizer conjugates has a magnetic contrast-enhancing agent, e.g., a paramagnetic ion, chelated thereto. Methods for medical imaging use imaging compositions containing the photosensitizer particle contrast agents.

  Disclosed herein are a novel perfluoroalkyl vinyl ether compound, a process for preparing a copolymer by using the perfluoroalkyl vinyl ether compound, and an optical plastic material comprising a copolymer prepared by the process. More specifically, the perfluoroalkyl vinyl ether has a particular molecular structure; the process is performed by copolymerizing the perfluoroalkyl vinyl ether compound with a common fluorinated olefin in the presence of a perfluorinated radical initiator; and, the optical plastic material comprises a copolymer prepared by the process and optionally a dopant. The copolymerization of the perfluoroalkyl vinyl ether with a common fluorinated olefin can provide a copolymer having a high molecular weight. In addition, appropriate control of the composition of the monomers can provide a completely amorphous copolymer. Since the polymer prepared by the process exhibits excellent thermal properties and is substantially transparent in the UV and near IR regions, it can be usefully applied to various optical plastic materials. Furthermore, a preform for a GI type plastic optical fiber fabricated by using the copolymer and the dopant has a high T g , thus being stable, and a parabolic refractive index profile due to the presence of the dopant.

  本文披露了一种新型的全氟烷基乙烯醚化合物，一种利用该全氟烷基乙烯醚化合物制备共聚物的方法，以及一种包括通过该方法制备的共聚物的光学塑料材料。具体而言，该全氟烷基乙烯醚具有特定的分子结构；该方法是在全氟基自由基引发剂的存在下，通过共聚合该全氟烷基乙烯醚化合物和常见的氟化烯烃来进行的；而且，该光学塑料材料包括通过该方法制备的共聚物和可选的掺杂剂。 全氟烷基乙烯醚与常见的氟化烯烃的共聚可以提供高分子量的共聚物。此外，适当控制单体的组成可以提供完全无定形的共聚物。由于该方法制备的聚合物具有优异的热性能，并且在紫外线和近红外区域具有较高的透明度，因此可以应用于各种光学塑料材料中。此外，使用该共聚物和掺杂剂制备的GI型塑料光纤预制件具有高Tg，因此稳定，并且由于存在掺杂剂而具有抛物线折射率剖面。
