  applying photocatalytic systems to activate substrates becomes increasingly popular. Although photosensitizers serve as the core of the photocatalytic reaction, the design of a photosensitizer has not been taken for granted. By modifying ligands of organometallic complexes to optimize properties of photosensitizers, we successfully achieved a series of iridium complexes with long excited triplet-state lifetime

  处于激发态的底物与相应的基态显着不同，因此它们被视为具有不同物理性质和化学反应性的不同化学物种。因此，将光催化系统用于活化基材变得越来越普遍。尽管光敏剂是光催化反应的核心，但是光敏剂的设计并不是理所当然的。通过修饰有机金属配合物的配体以优化光敏剂的性能，我们成功实现了一系列铱配合物，具有长激发三重态寿命，高三重激发态能量，强吸收性和鲁棒稳定性。评估了制备的铱配合物作为光敏剂对各种挑战性的光环加成反应（例如，

  specifically to sites of bone remodeling. To address this need, this study synthesized oligo(ethylene glycol) copolymers based on a peptide with high affinity to tartrate-resistant acid phosphatase (TRAP), an enzyme deposited by osteoclasts during the bone resorption phase of bone remodeling, which provides greater specificity relevant for bone cell drugging.

  药物向骨骼的递送具有挑战性，尽管开发了几种针对羟基磷灰石的骨靶向药物递送系统，但药物分布通常小于注射剂量的1％。这些以骨为靶标的药物输送系统仍然在骨内靶细胞定位不良，因为在任何给定时间，总骨量远大于具有相关细胞靶标（破骨细胞或成骨细胞）的急性重塑骨量。因此，需要将骨作用药物特异性地靶向骨重塑的部位。为了满足这一需求，本研究基于一种肽合成了一种低聚（乙二醇）共聚物，该肽与抗酒石酸酸性磷酸酶（TRAP）具有高亲和力，该酶是破骨细胞在骨重塑的骨吸收阶段沉积的酶，它提供了与骨细胞药物相关的更高的特异性。研究了梯度和随机肽的方向，以及聚合物的分子量。靶向TRAP的高分子量（M n）无规共聚物在重塑骨骼中表现出优异的蓄积性，其中观察到骨折蓄积至少1周，占组织分布的14％。M n和低M n的无规共聚物的累积量较低，表明停留时间取决于M n。清除了高M n梯度聚合物，只有1％的化合物在1周后仍然存在于骨折
• Synthesis of Well-Defined Polythiol Copolymers by RAFT Polymerization

  A simple methodology to prepare well-defined polythiol copolymers by RAFT polymerization was developed. A methacrylate monomer carrying a S-alkyl-O-ethyl xanthate moiety as thiol protecting group was prepared in two high yield steps. Polythiols were obtained by copolymerizing the, functional methacrylate and subsequent aminolysis of the. protecting groups. Model reactions and polymerizations showed that the S-alkyl-O-ethyl dithiocarbonate functionality h is fully compatible with the RAFT polymerization of methacrylates and did not induce any side reactions. Functionalization of polythiol copolymers was done via thiol-ene addition, Michael addition and thiol-disulfide exchange. Thiol deprotection and functionalization were done in one pot for Michael addition and thiol-disulfide exchange. A complete conversion of thiol groups was observed for all three types of reactions, exemplifying the potential of polythiol copolymers for the preparation of functional materials.
