Bacterichlorins possess a characteristic intense electronic absorption in the near-infrared part of electromagnetic radiation (NIR) from 700 nm up to 900 nm, where endogenous chromophores do not absorb and which allows deep penetration through tissues. Although naturally-occurring metal complexes derived bacteriochlorophylls are unstable their use is limited, it currently possible obtain large-scale libraries photostable synthetic compounds belonging bacteriochlorin family. This review presents an up-to-date overview most significant studies on synthesis, spectroscopic, photochemical, electrochemical characteristics as well various potential applications bacteriochlorins complexes. Particular emphasis has been given possibilities medicine, especially photodynamic therapy cancer (PDT), photodiagnosis (PD), inactivation (PDI) bacteria, viruses, fungi. The combination (metallo)bacteriochlorins with polymeric micelles, lipoproteins, nanoparticles, metal-organic frameworks order increase efficacy also discussed. Other discussed this paper include light-harvesting antennas, optical sensors, photocatalysts, dye-sensitized solar cells for efficient energy conversion.

In addition to the already described ligand L4a, two pyclen-based lanthanide chelators, L4b and L4c, bearing specific picolinate two-photon antennas (tailor-made for each targeted metal) one acetate arm arranged in a dissymmetrical manner, have been synthesized, form complete family of luminescent bioprobes: [EuL4a], [SmL4a], [YbL4b], [TbL4c], [DyL4c]. Additionally, symmetrically regioisomer L4a′ was also synthesized as well its [EuL4a′] complex highlight astonishing positive impact N-distribution functional chelating arms. The investigation clearly shows high performance bioprobe, which, depending on complexed lanthanide, could be used various applications. Each presents brightness, quantum yields, lifetimes. Staining complexes into living human breast cancer cells observed. addition, vivo microscopy performed first time zebrafish model with [EuL4a]. No apparent toxicity detected growth zebrafish, images quality were obtained.

Luminescent biosensing in the second near-infrared window (NIR-II, 1000–1700 nm) region, which has weak tissue scattering and low autofluorescence, draws extensive attention owing to its deep penetration, good spatial resolution high signal-to-background ratio. As a new generation of NIR-II probes, lanthanide (Ln3+)-containing nanoprobes exhibit several superior properties. With rapid development Ln3+-containing nanoprobes, many significant advances have been accomplished their optical properties tuning surface functional modification for further bioapplications. Rather than being exhaustive, this review aims survey recent design strategies inorganic luminescent by highlighting performance optimization approaches. Moreover, challenges opportunities kind novel are envisioned.

Phototheranostics constitute an emerging cancer treatment wherein the core diagnostic and therapeutic functions are integrated into a single photosensitizer (PS). Achieving full potential of this modality requires being able to tune photosensitizing properties PS in question. Structural modification organic framework represents time-honored strategy for tuning photophysical features given system. Here we report easy-to-implement metal selection approach that allows fine-tuning excited-state energy dissipation phototheranostics as exemplified by set lanthanide (Ln = Gd, Yb, Er) carbazole-containing porphyrinoid complexes. Femto- nanosecond time-resolved spectroscopic studies, conjunction with density functional theory calculations, revealed pathways PSs highly dependent on gap between lowest triplet excited state ligand states coordinated Ln ions. The Yb complex displayed balance deactivation mechanisms made it attractive combined photoacoustic imaging photothermal/photodynamic therapy agent. It was encapsulated mesoporous silica nanoparticles (MSN) provide biocompatible construct, YbL@MSN, which displays high photothermal conversion efficiency (η 45%) decent singlet oxygen quantum yield (ΦΔ 31%). Mouse model studies YbL@MSN both synergistic photothermal- photodynamic-therapy-based tumor reduction vivo. Our results lead us suggest promising phototheranostics.
