Abstract

The photoexcitation energy transfer is found and investigated in complexes of CdSe/ZnS cationic quantum dots and chlorin e6 molecules formed by covalent bonding and electrostatic interaction in aqueous solution and in porous track membranes. The quantum dots and chlorin e6 molecules form stable complexes that exhibit Förster resonance energy transfer (FRET) from quantum dots to chlorin e6 regardless of complex formation conditions. Competitive channels of photoexcitation energy dissipation in the complexes, which hamper the FRET process, were found and discussed.

摘要

在水溶液和多孔径迹膜中，通过共价键和静电相互作用形成的 CdSe/ZnS 阳离子量子点与氯卟啉 e6 分子的复合物中发现并研究了光激发能量转移。量子点和氯卟啉 e6 分子形成稳定的复合物，无论复合物形成条件如何，都表现出从量子点到氯卟啉 e6 的Förster 共振能量转移（FRET）。发现并讨论了复合物中阻碍 FRET 过程的光激发能量耗散的竞争途径。
