  甲苯磺酸妥舒沙星(TFLX)是一种新型喹诺酮类广谱抗菌药物,具有优异的抗菌杀菌能力,但存在水溶性差,口服固体制剂溶出度比较低的缺点.文献报道,利用羟丙基-β-环糊精为载体对难溶性药物进行包合,可有效改善药物的溶出度.因此,本研究以羟丙基-β-环糊精为载体,制备了甲苯磺酸妥舒沙星的包合物,利用紫外分光光度计和溶出仪对包合前后的药物溶出进行比较,结果发现:TFLX在pH=1.2的模拟胃液中溶出度由87.8%增加到98.1(见图1),在pH=6.8的模拟肠液中溶出度由14.0%增加到31.2%(见图2).

自从Forresr等1998年首次利用铂化合物实现了高效电致发光以来,有机铂磷光材料的研发引起了人们的极大兴趣[1,2].但四方平面构型的铂化合物常由于分子间相互作用而降低发光效率和色纯度,因此限制了铂类磷光材料的应用[3].本课题组利用ppy作为环金属配体,2-(2’-二苯基膦氧基苯)苯并咪唑为解聚配体合成了新型金属有机铂化合物(Pt-1),光学性质研究表明Pt-1具有高效的单分子磷光性质,固体
