Construction of polysiloxane-based fluorescent probe for visualizing pH down-regulation

Changes in the intracellular pH values constitute a significant physiological and pathological process and play vital roles in autophagy, self-repairing, and programmed cell apoptosis. A unique fluorescent probe (PN-1) based on polysiloxanes designed using the intramolecular charge transfer (ICT) mechanism has been developed for the detection of the pH down-regulation process for the first time.PN-1has been successfully applied to HeLa cells and HepG2 cells for visualizing the pH value changes in a ratiometric manner. The result presented that, in the normal intracellular autophagy process,PN-1displayed strong blue fluorescence while starvation induced apparent red fluorescence ofPN-1. In addition, the inhibitory effect of chloroquine (CQ) to pH value changes during the cell starvation treatment process has been analyzed. The work indicated that a polysiloxane-based fluorescent probe could be applied to detect pH value changes during autophagy, and paved a new avenue for the further design of fluorescent probes for monitoring pH changes.

Synthesis and properties of new two-photon absorption chromophores containing 3,5-dicyano-2,4,6-tristyrylpyridine as the core

This paper reports the synthesis of a series of donor-substituted 3,5-dicyano-2,4,6-tristyrylpyridine derivatives, having two-dimensional branched D-π-A structures, as new two-photon absorption (TPA) chromophores. These chromophores are stilbene-type chromophores containing the same acceptor group but end-capped with different aromatic groups as the donors. Measured as the two-photon-induced fluorescence in chloroform solvent, using a femtosecond multipass Ti:sapphire amplifier as the irradiation source, the TPA cross section values of some compounds are on the order of 10-48 cm4 s photon-1. These chromophores also have relatively high two-photon-excited fluorescence (TPEF) action cross sections. Pumped by the laser at 800 nm, these chromophores show efficient two-photon-induced orange-red fluorescence emission. The experimental results indicate that the different end-capped functional electronic donors and the number of branches of these chromophores affect their one-photon properties, two-photon up-conversion emission behavior and TPA cross section values. Especially, with increasing numbers of branches, λmaxabs and λmaxspf exhibit bathochromic shifts, while their two-photon absorption cross sections also increase. Compared with the two-branched chromophore 6, the tribranched chromophore 4 shows a larger TPA cross section, and the cooperative enhancement of the TPA cross section from 6 to 4 is 1.2-fold at 800 nm.

Fluorescent probe with fluorescence imaging and photodynamic functions and nano preparation and preparation method thereof

The invention belongs to the technical field of pharmacology and pharmacy, and relates to a fluorescent probe with NIR II fluorescence imaging and photodynamic therapy performance, and a nano preparation and a preparation method thereof. The fluorescent molecule takes substituted triphenylamine or tetraphenyl ethylene coupled ethylenedioxythiophene coupled bibenzothiadiazole/selenium/tellurium diazole as a parent nucleus, and has NIR II fluorescence imaging and active oxygen generation performance. The nano preparation with good NIR II fluorescence imaging and photodynamic therapy effects is prepared from synthetic phospholipids such as phospholipid moleculeds, dipalmitoyl phosphatidyl choline and distearoyl phosphatidylcholine, natural phospholipids such as phosphatidylcholine, or distearoyl phosphatidylethanolamine-polyethylene glycol and derivatives thereof or albumin or polyethylene glycol segmented copolymers and the fluorescence molecules. The preparation emits NIR II fluorescence under the irradiation of near-infrared light and generates ROS, so that the tumor photodynamic therapy guided by fluorescence images can be realized. And the aim of integrating tumor diagnosis and treatment is fulfilled.

Guest Inclusion Modulates Concentration and Persistence of Photogenerated Radicals in Assembled Triphenylamine Macrocycles

Substituted triphenylamine (TPA) radical cations show great potential as oxidants and as spin-containing units in polymer magnets. Their properties can be further tuned by supramolecular assembly. Here, we examine how the properties of photogenerated radical cations, intrinsic to TPA macrocycles, are altered upon their self-assembly into one-dimensional columns. These macrocycles consist of two TPAs and two methylene ureas, which drive the assembly into porous organic materials. Advantageously, upon activation the crystals can undergo guest exchange in a single-crystal-to-single-crystal transformation generating a series of isoskeletal host-guest complexes whose properties can be directly compared. Photoinduced electron transfer, initiated using 365 nm light-emitting diodes, affords radicals at room temperature as observed by electron paramagnetic resonance (EPR) spectroscopy. The line shape of the EPR spectra and the quantity of radicals can be modulated by both polarity and heavy atom inclusion of the encapsulated guest. These photogenerated radicals are persistent, with half-lives between 1 and 7 d and display no degradation upon radical decay. Re-irradiation of the samples can restore the radical concentration back to a similar maximum concentration, a feature that is reproducible over several cycles. EPR simulations of a representative spectrum indicate two species, one containing two N hyperfine interactions and an additional broad signal with no resolvable hyperfine interaction. Intriguingly, TPA analogues without bromine substitution also exhibit similar quantities of photogenerated radicals, suggesting that supramolecular strategies can enable more flexibility in stable TPA radical structures. These studies will help guide the development of new photoactive materials.
