Croconaine rotaxane for acid activated photothermal heating and ratiometric photoacoustic imaging of acidic pH

Absorption of 808 nm laser light by liposomes containing a pH sensitive, near-infrared croconaine rotaxane dye increases dramatically in weak acid. A stealth liposome composition permits acid activated, photothermal heating and also acts as an effective nanoparticle probe for ratiometric photoacoustic imaging of acidic pH in deep sample locations, including a living mouse.

PH reversible activation type photo-thermal/photodynamic/fluorescent integrated probe molecule

The invention discloses a pH reversible activation type photo-thermal/photodynamic/fluorescent integrated probe molecule, and belongs to the technical field of biological medicines. A pH-responsive asymmetric cyanine structure is used as a core unit, and through structural modification and introduction of halogen and other heavy atoms into a conjugated system, a photo-thermal/photodynamic/fluorescent integrated probe molecule capable of being specifically activated by a tumor weakly acidic microenvironment is constructed. The photo-thermal/photodynamic/fluorescent integrated probe has good stability, a good photo-thermal effect and excellent active oxygen generation capacity, and has huge potential in tumor treatment.

Effects of Substituents on Metastable-State Photoacids: Design, Synthesis, and Evaluation of their Photochemical Properties

Recently, metastable-state photoacids have been widely used to control proton transfer in numerous chemical and biological processes as well as applications with visible light. Generally, substituents have a great influence on the photochemical properties of molecules, which will further affect their applications. Yet, the effects of substituents on metastable-state photoacids have not been studied systematically. In this work, 16 metastable-state photoacid derivatives were designed and synthesized on the basis of substituents having a large range of σ–π electron–donor–acceptor capabilities. The effects of substituents on the color display [or maximum absorption band(s)], solubility, pKa values, dark/photoacidity, photosensitivity, and relaxation kinetic(s) were investigated in detail. This study will be helpful for the targeted design and synthesis of promising photoacids and the application of their photocontrolled proton-release processes in functional materials/devices.
