Fluorescent sensing film decorated with ratiometric probe for visual and recyclable monitoring of Cu2+

Specifically, visually, and quantitatively monitor copper ion (Cu2+) is critical in the area of biological and environmental detection. Herein, a ratiometric fluorescent probe with benzoxazole appended xanthenes skeleton was constructed and further employed to monitor Cu2+ in Hela cells, real water samples, and test strips. An easily distinguishable colorimetric (colorless to red) and fluorescence (green to red) change could be observed by naked eye under the portable UV lamp (365 nm) and the changes could be recovered by adding S-2. Furthermore, electrospinning technique was employed to fabricate a probe composited fluorescent sensing film (PMMA) for realizing the visual and recyclable monitoring of Cu2+, indicating that the probe-composited fluorescent sensing film has great potential for on-site and naked-eye detection of Cu2+ in practical.

The effects of the heteroatom and position on excited-state intramolecular proton transfer of new hydroxyphenyl benzoxazole derivatives: a time-dependent density functional theory study

The effects of the heteroatom and position on excited-state intramolecular proton transfer (ESIPT) of 2-[4 ‘-(N-4,6-dichloro-1,3,5-triazi-n-2-yl)2 ‘ hydroxyphenyl]benzoxazole (4THBO) have been investigated via time-dependent density functional theory studies. The heteroatoms refer to O and S atoms, and the position effect refers to the N-4,6-trichloro-1,3,5-triazin-2-yl (TCT) substituents in the para and meta positions. The configuration of the four compounds (4THBO, 4THBT, 5THBO and 5THBT) was optimized and the bond lengths, bond angles and infrared spectra of the atoms participating in the proton transfer in the S0 and S1 states were studied. The occurrence of ultrafast ESIPT in the four compounds was demonstrated. Moreover, the potential energy curves of the S0 and S1 states were constructed, and the effects of the heteroatom substitution and substituent position changes on the ESIPT mechanism of the four 4THBO derivatives were analyzed. The results show that the ESIPT barrier of the S atom substitution in the excited state is lower than that of the O atom-substituted molecule, and the energy barrier of the substituent (TCT) in the meta-position is significantly smaller than that in the para-position. These results indicate that the substitution of the S heteroatom promotes the ESIPT of the 4THBO compound and that the substituent (TCT) in the para position is more prone to proton transfer than that in the meta position. Our work could provide a theoretical basis for further experiments.

New steroidal oxazolines, benzoxazoles and benzimidazoles related to abiraterone and galeterone

Seven new oxazoline, benzoxazole and benzimidazole derivatives were synthesized from 3 beta-acetoxyandrosta-5,16-dien-17-carboxylic, 3 beta-acetoxyandrost-5-en-17 beta-carboxylic and 3 beta-acetoxypregn-5-en-21-oic acids. Docking to active site of human 17 alpha-hydroxylase/17,20-lyase revealed that all oxazolines, as well as benzoxazoles and benzimidazoles comprising Delta(16) could form stable complexes with enzyme, in which steroid moiety is positioned similarly to that of abiraterone and galeterone, and nitrogen atom coordinates heme iron, while 16,17-saturated benzoxazoles and benzimidazoles could only bind in a position where heterocycle is located nearly parallel to heme plane. Modeling of the interaction of new benzoxazole and benzimidazole derivatives with androgen receptor revealed the destabilization of helix 12, constituting activation function 2 (AF2) site, by mentioned compounds, similar to one induced by known antagonist galeterone. The synthesized compounds inhibited growth of prostate carcinoma LNCaP and PC-3 cells at 96 h incubation; the potency of 2′-(3-hydroxyandrosta-5,16-dien-17-yl)-4′,5′-dihydro-1′,3′-oxazole and 2′-(3 beta-hydroxyandrosta-5,16-dien-17-yl)-benzimidazole was superior and could inspire further investigations of these compounds as potential anti-cancer agents.

Probing the Interaction of Nucleobases and Fluorophore-Tagged Nucleobases with Graphene Surface: Adsorption and Fluorescence Studies

Adsorption of a fluorophore-labeled DNA oligonucleotide by graphene nano-probes is of interest to exploit as bio-sensing material. This work reports the fluorescence properties of fluorophore tagged nucleobases on the graphene surface computationally. The interaction of nucleobases and fluorophore tagged nucleobases to the graphene surface examined using M062X/6-31G(d) level of theory in the gas phase and ethanol solvent. The binding energies of nucleobases on the graphene surface in the gas phase follows the order: G>A >= C >= T in agreement with the previous reports. The slab model calculations performed with LDA/PWC/DND level of theory also revealed a similar binding affinity on the graphene surface in the gas phase. The fluorescence of benzoxazole as fluorophore tagged with nucleobase on graphene surface was investigated using TD-DFT M06-2X/6-31G(d) level of theory. The binding preference of the fluorophore tagged nucleobases is not significantly different in ethanol solvent. The aromaticity of the nucleobases tagged fluorophore on the graphene surface was investigated by NICS (1) and NICS (1)(zz) calculations and the aromaticity was found to be increased upon interaction with the graphene surface. The fluorescence quenching upon binding of fluorophore tagged nucleobases on graphene surface revealed the importance of purine nucleobases and found to be more prominent with guanine tagged fluorophore.

Theoretical exploration about the ESIPT mechanism and hydrogen bonding interaction for 2-(3,5-dichloro-2-hydroxy-phenyl)-benzoxazole-6-carboxylicacid

Excited state hydrogen bonding interactions and the excited state dynamical behaviors are of paramount importance in the photochemical and photophysical fields. In the present work, based on density functional theory and time-dependent density functional theory methods, we theoretically explore the excited state hydrogen bonds and excited state intramolecular proton transfer (ESIPT) mechanism for the novel 2-(3,5-dichloro-2-hydroxy-phenyl)-benzoxazole-6-carboxylicacid (DHPB) system. Firstly, comparing the non-hydrogen bond DHPB-O form with DHPB, we confirm the formation of hydrogen bond in DHPB molecule in the S-0 state. Upon the investigations about the stable excited state structure (ie, geometrical parameter, infrared vibrational spectra, and simulated bond energy), we verify that intramolecular hydrogen bond OHN should be strengthened in the first excited state. The simulated hydrogen bonding energy via constructing potential energy curves further confirms the strengthening phenomenon of OHN for DHPB system. In view of photoexcitation, the charge redistribution around hydrogen bonding moieties reveals that the increased electronic densities facilitate attracting hydrogen proton. On the basis of B3LYP, Cam-B3LYP, and PBE0 functionals, we further construct the potential energy surfaces along with ESIPT reaction path, which demonstrates that the ESIPT process is ultrafast because of the low potential barrier. It explains the reason about why the normal fluorescence cannot be observed in previous experimental phenomenon. This work fills vacancy of ESIPT mechanism for DHPB system and presents the unambiguous dynamical behavior legitimately.

Synthesis and DSSC application of triazole bridged dendrimers with benzoheterazole surface groups

Triazole bridged dendrimers with benzoheterazole surface groups were successfully synthesized in high yields by click chemistry via convergent approach. The photophysical properties of the dendrimers reveal that as the generation increases the light absorption ability also increases. The fluorescence intensity gradually decreases as the dendritic generation increases because of fluorescence quenching due to steric crowding of the dendritic arms. On increasing the number of benzoheterazole unit at periphery, the anodic peak was shifted to higher positive potential in cyclic voltammetry. When the synthesized triazole dendrimers are utilized as an additive in the redox couple of a DSSC, the lower generation dendrimers showed better current generating capacity with higher power conversion efficiency than the higher generation dendrimers.
