Prospects for More Efficient Multi-Photon Absorption Photosensitizers Exhibiting Both Reactive Oxygen Species Generation and Luminescence

The use of two-photon absorption (TPA) for such applications as microscopy, imaging, and photodynamic therapy (PDT) offers several advantages over the usual one-photon excitation. This creates a need for photosensitizers that exhibit both strong two-photon absorption and the highly efficient generation of reactive oxygen species (ROS), as well as, ideally, bright luminescence. This review focuses on different strategies utilized to improve the TPA properties of various multi-photon absorbing species that have the required photophysical properties. Along with well-known families of photosensitizers, including porphyrins, we also describe other promising organic and organometallic structures and more complex systems involving organic and inorganic nanoparticles. We concentrate on the published studies that provide two-photon absorption cross-section values and the singlet oxygen (or other ROS) and luminescence quantum yields, which are crucial for potential use within PDT and diagnostics. We hope that this review will aid in the design and modification of novel TPA photosensitizers, which can help in exploiting the features of nonlinear absorption processes.

“…In the third case the solvent molecules are located in channels or other large cavities without specific requirements for solvate shape and size or sometimes even interactions, and in such case different solvents used in the crystallization often in unspecified ratio and usually in non-stoichiometric amount can incorporate in the structure, e.g. [31][32] by forming a mixed solvate.…”

In this study we present a detailed crystallographic analysis of multiple solvates of an antibacterial furazidin. Solvate formation of furazidin was investigated by crystallizing it from pure solvents and solvent-water mixtures. Crystal structure analysis of the obtained solvates and computational calculations were used to rationalize the main factors leading to the intermolecular interactions present in the solvate crystal structures as well as resulting in formation of the observed solvates and solvate hydrates. Furazidin forms pure solvates and solvate hydrates with solvents having large hydrogen bond acceptor propensity as well as with a hydrogen bond donor and acceptor formic acid. In solvate hydrates the incorporation of water allows formation of additional hydrogen bonds and results in more efficient hydrogen bond network in which water is “hooking” the organic solvent molecule, and this slightly reduces the cut-off of solvent hydrogen bond acceptor propensity required for obtaining a solvate. The crystal structures of all pure solvates are formed from molecule layers and in almost all structures solvent is hydrogen bonded to the furazidin, but the packing in each solvate is unique. In contrast, the hydrogen bonding and packing in most solvate hydrates are nearly identical.

“…22−25 Additionally, in part of the heterosolvates, solvent molecules are located in channels or other large cavities without specific requirements for the solvate shape and size or even interactions. 26,27 In general, the reason for facile inclusion of water in the crystal structures is well known and is the small size, orientational freedom, and versatile hydrogen bonding capabilities of water molecules, 28 as water can act as a hydrogen bond acceptor and donor. The latter ability explains its incorporation in the solvate hydrates, as most organic solvates only have a hydrogen bond acceptor functionality.…”
