Discrimination of live and apoptotic cells is a crucial task in the research of pharmacology, biology, pathology, and medicine science. Recently, up-conversion (UC) luminescent materials have appealed much attention due to their unique ability to convert low energy excitation photons to high energy ones. However, UC fluorescence has not been employed in the field of discrimination of live and apoptotic cells. We present a facile and costless St?ber method to fabricate robust silica nanoparticles (SiO2 UCNPs) exhibiting several merits, such as narrow size distribution and UC luminescence. SiO2 UCNPs could discriminate live and apoptosis cells by taking advantage of the unique surface property of SiO2 UCNPs for the first time. This work is also the first demonstration of the use of single photon excited UC fluorescence derived from nanoparticles for biological recognition of a specific type of cells.

Specific targeting towards tumors and the on-site activation of photosensitizers to diagnose tumors and reduce side effects for patients are currently the main challenges for photodynamic therapy (PDT) in the clinic. Herein, uniform diiodostyryl bodipy co
Triarylamine-BODIPY derivatives: A promising building block as hole transporting materials for efficient perovskite solar cells
Ortiz, Alejandro
, (2019)
In this work, the syntheses and characterization of four new TPA-BODIPY dyads as hole-transporting layers (HTLs) are reported. The photophysical and electrochemical properties of the dyads BTPA-I, BTPA-II, BTPA-III and BTPA-IV are investigated in solution and compared with the reference compounds BDP, BDP1, BDP2, TPA, A (triphenylamine) and B (4,4′-dimethoxitriphenylamine). The TPA-BODIPY derivatives strongly absorb visible light and upon photoexcitation at the BODIPY unit, these dyads undergo photoinduced electron transfer to form the corresponding charge-separated species, which was confirmed by solvatochromic measures of fluorescence. Their redox potentials and photophysical properties suggested that the new BTPAs derivatives showed a better ionization potential that free triphenylamines, which makes them promising candidates to use as hole transport layers (HTLs).

The optical limiting properties of a series of near infrared absorbing 3,5-dithienylenevinylene BODIPY (boron-dipyrromethene) dyes (1–3) that contain donor and acceptor moieties in their π-conjugation systems were studied by using the z-scan technique at

2,6-Diiodobodipy-styrylbodipy dyads were prepared to study the competing intersystem crossing (ISC) and the fluorescence-resonance-energy-transfer (FRET), and its effect on the photophysical property of the dyads. In the dyads, 2,6-diiodobodipy moiety was

Singlet oxygen (1O2) generated from the photosensitization process within tumor tissues during photodynamic therapy (PDT) is self-limiting. Fractional delivery of light tends to be a better method for PDT. Herein, BDPIA with a high 1O2 quantum yield (QY) of 70% in DCM has an additional anthracene module for capturing 1O2, which would be useful in PDT. In the light cycle, the endoperoxide of anthracene is generated with singlet oxygen while in the dark cycle, the endoperoxide undergoes thermal cycloreversion to produce 1O2, regenerating the anthracene module. Therefore, the photodynamic process can continue in the dark period and the light cycles, promising their continuous phototherapy efficacy. In addition, BDPIA NPs in water exhibit a high photothermal conversion efficiency (η = 38.9%) for effective photothermal therapy. In vitro MTT assay shows that BDPIA NPs have a low half inhibitory concentration (IC50) of 6.293 μg mL-1 on HeLa cells. Furthermore, lentiviral vector transfected HeLa cell lines with red fluorescent proteins were used to perform real time in vivo fluorescence imaging guided phototherapy. The model can monitor the real-time uptake of BDPIA NPs. The results indicate that BDPIA NPs are capable of inhibiting cell proliferation even at a low dosage (0.2 mg kg-1) while the normal tissues (heart, liver, spleen, lung and kidney) suffer from no side effects. Our results demonstrate that BDPIA NPs with high phototoxicity, low dark toxicity and excellent bio-compatibility can be used as a potential photosensitizer for continuous photodynamic and photothermal synergistic therapy.

Two AIE-active chiral BINOL-based O-BODIPY enantiomers (R/S-5) were synthesized and showed mirror-image red-color CPL induced via intramolecular energy transfer. The chiroptical properties of the molecules indicate that the chirality of electronic ground
Self-Assembly of Novel Thiophene-Based BODIPY RuII Rectangles: Potential Antiproliferative Agents Selective Against Cancer Cells
Gupta, Gajendra,Das, Abhishek,Panja, Sourav,Ryu, Ji Yeon,Lee, Junseong,Mandal, Nripendranath,Lee, Chang Yeon
, p. 17199 - 17203 (2017)
Novel Ru (2+2) rectangles were designed and synthesized by self-assembly of a new thiophene-functionalized dipyridyl BODIPY ligand, BDPS, and ruthenium(II) precursors. The complexes exhibited dose-dependent antiproliferative activities against cancer cells, in which some compounds selectively kill cancer cells. The net fluorescence due to BODIPY allowed us to visualize their location inside cancer cells. Moreover, the metalla-rectangles displayed substantial propensity to bind with biomolecules.
