Abstract
Herein we describe the rational design, synthesis and photophysical study of a novel class of phenanthridine-based, one- and two-photon sensitive, photoremovable protecting groups with absorption wavelengths extending beyond 400 nm. This design facilitated the development of scaffolds with enhanced uncaging quantum yield, paving the way for broader applications in controlled drug delivery and molecular manipulation.

Abstract
Phenols confer bioactivity to a plethora of organic compounds. Protecting the phenolic functionality with photoremovable protecting groups (PPGs) sensitive to two-photon excitation (2PE) can block the bioactivity and provide controlled release of these compounds in a spatially and temporally restricted manner by photoactivation with IR light. To develop an efficient 2PE-sensitive PPG for releasing phenols, the (8-cyano-7-hydroxyquinolin-2-yl)methyl (CyHQ) chromophore was functionalized at the C4 position with methyl, morpholine, methoxy, para-tolyl, and 3,4,5-trimethoxyphenyl groups to provide 4-methyl-CyHQ (Me-CyHQ), 4-morpholino-CyHQ (Mor-CyHQ), 4-methoxy-CyHQ (MeO-CyHQ), 4-(p-tolyl)-CyHQ (pTol-CyHQ), and 4-(3,4,5-trimethoxyphenyl)-CyHQ (TMP-CyHQ) PPGs. The probes possess attributes useful for biological use, including high quantum yield (Φu), hydrolytic stability, and good aqueous solubility in physiological conditions. The MeO-CyHQ PPG enhanced the two-photon uncaging action cross section (δu) of dopamine 3.5-fold (0.85 GM) compared to CyHQ (0.24 GM) at 740 nm and 1.49 GM at 720 nm. MeO-CyHQ was used to mediate photoactivation via 2PE of serotonin, rotigotine, N-vanillyl-nonanoylamide (VNA) (a capsaicin analogue), and eugenol. The constructs except rotigotine showed excellent efficiency in 2PE with δu ranging from 0.75 to 1.01 GM at 740 nm and from 1.31 to 1.36 GM at 720 nm high yielding release of the payloads. These probes also performed well by using conventional single photon excitation (1PE). The spatially and temporally controlled release of dopamine from CyHQ-DA and MeO-CyHQ-DA and serotonin (5-HT) from MeO-CyHQ-5HT was quantified in cell culture by using genetically encoded sensors for dopamine and serotonin, respectively. Calcium imaging was employed to quantify the release of VNA and eugenol (EG) from MeO-CyHQ-VNA and MeO-CyHQ-EG, respectively. These tools will enable experiments to understand the intricate mechanisms involved in neurological signaling and the roles played by neurotransmitters, such as dopamine and serotonin, in the activation of their respective receptors.

Abstract
Photolabile protecting groups (PPGs) releasing bioactive compounds upon two-photon excitation have emerged as increasingly popular tools to control and study physiological processes. Yet the limited two-photon photosensitivity of many cages is still a critical issue for applications. We herein report the design, synthesis and photophysical study of polarized extended coumarinyl derivatives which show large two-photon sensitivity (up to 440 GM) at two complementary wavelengths in the NIR spectral range. DFT calculations demonstrate that subtle tuning of polarization in the ground-state and confinement of the photo-induced intramolecular charge transfer upon excitation is responsible for enhancing two-photon absorption while maintaining large uncaging efficiency. These findings open a new engineering route towards efficient coumarinyl PPGs.

Abstract
A systematic study on quinoline‐derived light sensitive probes, having third‐order rotational symmetry is presented. The electronically linked octupolar structures show considerably improved linear and nonlinear photophysical properties under one‐ and two‐photon irradiation conditions compared to the corresponding monomers. Photolysis of the three acetate derivatives shows strong structure dependency: whereas irradiation of the 6‐ and 7‐aminoquinoline derivatives resulted in fast intramolecular cyclization and only trace amounts of fragmentation products, the 8‐aminoquinoline derivative afforded clean and selective photolysis, with a sequential release of their acetate groups (δu[730]=0.67 GM).

Abstract
Hg(ii)-mediated hydration reactions of unsymmetrical quinoline type tolans were studied. The observed accelerated reactions of the tolans rely on the additional binding motifs of the tolan, as supported by the X-ray structure of the macrocycle (2b). The analyte-specific reaction allows us to detect Hg(ii) in buffered media.

Abstract
Tandem uncaging systems in which a two-photon absorbing module and a cage moiety, linked via a phosphorous clip, that act together by Förster resonance energy transfer (FRET) have been developed. A library of these compounds, using different linkers and cages (7-nitroindolinyl or nitroveratryl) has been synthesized. The investigation of their uncaging and two-photon absorption properties demonstrates the scope and versatility of the engineering strategy towards efficient two-photon cages and reveals surprising cooperative and topological effects. The interactions between the 2PA module and the caging moiety are found to promote cooperative effects on the 2PA response while additional processes that enhance the uncaging efficiency are operative in well-oriented nitroindoline-derived dyads. These synergic effects combine to lead to record two-photon uncaging cross-section values (i.e., up to 20 GM) for uncaging of carboxylic acids.

Abstract
Three dyads with a fluorene derivative as an electron-donor and with electron-acceptors of variable redox potentials were synthesized as models for two-photon activated uncaging via electron transfer. A spectroscopic and photophysical study of the component units and the dyads in solvents of different polarities demonstrated an efficient electron transfer (efficiencies > 80%) followed by charge recombination in the arrays (30 ps < τ < 1.6 ns). Recombination takes place to the ground state in all cases except for the dyad displaying the highest driving force for charge recombination in the apolar solvent. The effects of changing the solvent polarity, as well as the driving force, for electron-transfer are discussed in the frame of the current theories of electron transfer.

Abstract
Improved photo-labile protecting groups, with high sensitivity to two-photon excitation, are needed for the controlled release of drugs, as tools in neuroscience and physiology. Here we present a new modular approach to the design of caging groups based on photoinduced electron transfer from an electron-rich two-photon dye to an electron acceptor, followed by scission of an ester to release a carboxylic acid. Three different electron acceptors were tested: nitrobenzyl, phenacyl and pyridinium. The nitrobenzyl system was ineffective, giving only photochemical decomposition and no release of the carboxylic acid. The phenacyl system also performed poorly, liberating the carboxylic acid in 20% chemical yield and 0.2% photochemical yield. The pyridinium system was most successful, and was tested for the release of two carboxylic acids: γ-amino butyric acid (GABA) and tryptophan. The caged GABA undergoes photochemical cleavage with a chemical yield of >95% and a photochemical yield of 1%; it exhibits a two-photon absorption cross section of 1100 GM at 700 nm, corresponding to a two-photon uncaging cross section of 10 ± 3 GM.
