WebPhotodynamic therapy (PDT) is a promising method for the treatment of cancer, because of its advantages including a low toxicity, non-drug-resistant character, and targeting … Intersystem crossing (ISC) is an isoenergetic radiationless process involving a transition between the two electronic states with different spin multiplicity. See more When an electron in a molecule with a singlet ground state is excited (via absorption of radiation) to a higher energy level, either an excited singlet state or an excited triplet state will form. Singlet state is a molecular See more Once a metal complex undergoes metal-to-ligand charge transfer, the system can undergo intersystem crossing, which, in conjunction with the … See more In 1933, Aleksander Jabłoński published his conclusion that the extended lifetime of phosphorescence was due to a metastable excited state at an energy lower than the state … See more Fluorophores Fluorescence microscopy relies upon fluorescent compounds, or fluorophores, in order to image … See more • Internal conversion (chemistry) • Michael Kasha • Population inversion See more
WebFurthermore, the efficiency of PS to generate ROS is highly dependent on intersystem crossing (ISC). 14–16 The scientists found that through the HOMO-LUMO design of the D-π-A structure, the ISC can be tuned such that the energy gap between the triplet state (T1) and the singlet state (S1) is small. 17–20 WebPhotodynamic therapy (PDT) is a promising method for the treatment of cancer, because of its advantages including a low toxicity, non-drug-resistant character, and targeting capability. From a photochemical aspect, a critical property of triplet photosensitizers (PSs) used for PDT reagents is the intersystem crossing (ISC) efficiency. Conventional PDT …
WebThen, the excitons will undergo an intersystem crossing (ISC) process to triplet STE state, where some of them are quickly self-trapped to relatively high energy states, enabling the blue light (~470 nm) emission, while the rest will transfer to low energy STE state, finally resulting in the highly efficient deep-red emission with a large ...
