WebAfter that, intersystem crossing (ISC) process occurs (k ISC = 3.3 × 109 s–1), which generates the triplet excited state of the NDI ligand (τ = 28.1 μs). The overall excited-state dynamics are fairly similar in both nonpolar toluene and polar benzonitrile, indicating that photoinduced charge separation dynamics between BDP and NDI is insignificant. WebMoreover, the radiatory and non-radiative as well as the intersystem crossing (ISC) and revoke intersystem crossing ... The skills on undergoing efficiently stabilizing processes from the excited stay permitted the novel BTD derivative to been used as a stable probe for bioimaging applications.
WebThe dynamics of spin flips induced by the femtosecond laser are theoretically investigated in this article. The spin flips in this scenario are attributed to the intersystem crossing … 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 reagents …
WebAiming at overcoming this barrier, there have been studies on the use of longer-lived triplet excitons, which can be introduced either through triplet sensitization by doping or through the use of donor materials containing heavy atoms that allow for intersystem crossing (ISC).
