Spin-orbit charge transfer-induced intersystem crossing (SOCT-ISC) is a promising method to design heavy atom-free triplet photosensitizers (PSs). Herein, a new organic triplet PS, BDP-An (Bodipy-phenylethynyl anthracene dyad) has been synthesized and studied. In polar solvents, charge transfer (CT) emission band was observed, and the singlet oxygen quantum yield (ΦΔ) is up to 95%. From femtosecond transient absorption […]

The development of new solar-to-fuel scenarios is of great importance, but the construction of molecular systems that convert sunlight into chemical energy represents a challenge. One specific issue is that the molecular systems have to be able to accumulate redox equivalents to mediate the photodriven transformation of relevant small molecules, which mostly involves the orchestrated […]

A series of CaF2-doped phosphors was synthesized in situ in hydrothermal conditions (in a DAB- 2 reactor), in the presence of sodium citrate as a complexing agent preventing premature precipitation. The materials were doped with Yb3+/Er3+ pair of ions, which resulted in up-conversion emission. Additionally, Mn2+ ions were incorporated into the structure of the CaF2 […]

Down conversion of solar UV and blue light is one of the few ways of surpassing the Shockley-Queisser limit of solar cells. One of the most efficient down conversion systems is the Pr3+ – Yb3+ lanthanide pair. However, these ions do not provide any strong absorption for solar UV and blue light, thus require sensitizing. In this work, […]

Phase-changing nanodroplets are sub-micron constructs with perfluorocarbon liquid cores that can be remotely vaporized with optical or acoustic energy to form gaseous microbubbles and expel their contents. This process can generate shock waves, shear forces, and microstreams in the interstitial tumor space, enhancing intratumoral drug delivery1. Furthermore, the resulting microbubbles can act as ultrasound contrast […]
