Membrane technology operating in highly concentrated solutions is essential in pressure retarded osmosis (PRO) applications to compete with other renewable energy technologies. Herein, we fabricated highly porous and robust electrospun membranes (ESMs) using a poly(benzoxazole-co-imide) (PBO) polymer. For the first time in osmotic-driven systems, novel one-step direct fluorination was adopted to increase hydrophilicity of the ESM. Direct fluorination increased the total surface energy of the ESM by boosting polar surface energy parameter, which eventually affected the formation of ‘ridge & valley’-like thin film composite membrane (PBO-TFC-F5) through interfacial polymerization of the fluorinated ESM. As a result, PBO-TFC-F5 achieved an unprecedented power density of 87.2 W m(-2) using 3 M NaClaq as a draw solution at 27 bar. When PBO-TFC-F5 was used for osmotic heat engine (OHE), it showed a power generation cost of only 203 $center dot MWh(-1), which was less than half the cost observed using commercial membranes. This robust, porous, and high performance PBO-TFC-F5 opens up new possibilities in membrane-based power generation systems.

Solution and solid-state Excited-State Intramolecular Proton Transfer (ESIPT) emitters incorporating Bis-triethyl-or triphenylsilylethynyl units

Excited-State Intramolecular Proton Transfer (ESIPT) emitters based on a 2-(2′-hydroxyphenyl)benzazole (HBX) scaffold, incorporating triethyl- or triphenylsilyl substituents either at the 3′,5′ positions of the benzoxazole ring or at the 3,5 positions of the phenol cycle have been synthesized through an expedite two-steps synthetic route. Upon excitation and depending on the substitution and environment, these fluorophores display either single (keto) or dual (enol/keto) fluorescence emission spanning from 400 to 570 nm. Unlike the majority of reported ESIPT emitters, these rigidified dyes display intense fluorescence intensity in the solution-state in either aprotic apolar (toluene) or protic polar (ethanol) solvents with observed emission quantum yields (QY) up to 52% and 44%, respectively. These values represent a drastic enhancement as compared to unsubstituted HBX dyes which feature QY between 1 and 2% in toluene. These fluorophores remain highly emissive in the solid-state, as dispersed in KBr pellets or doped in PMMA films (QY up to 77% and 60% respectively). Molecular engineering studies showed that it is possible to fine-tune the emission color with very small modifications of the HBX scaffold. The nature of the excited-states was also probed through ab initio calculations, evidencing in each case a transition from the K* state.

A theoretical study on excited state proton transfer in 2-(2 ‘-dihydroxyphenyl) benzoxazole

This research investigates the dynamic excited state process for a novel system 2-(2-dihydroxyphenyl) benzoxazole (DHBO) for excited state proton transfer (ESPT) process based on density functional theory (DFT) and time-dependent DFT (TDDFT) methods. Because 2 intramolecular hydrogen bonds (O-1?H2N3 and O-4?H5O6) in DHBO molecules may trigger proton transfer process in the S-1 state, we focus on these 2 hydrogen bonds. Our results show that only the O-1?H2N3 bond has obvious changes in both bond length and bond angle upon photoexcitation. Charge redistribution also confirms that hydrogen bond wire (O-1?H2N3) is the best way to achieve the ESPT process in the S-1 state. Considering the ESPT mechanism, our theoretical potential energy curves of DHBO indicate that only the excited state single-proton transfer process occurs via O-1?H2N3 rather than O-4?H5O6. We believe that our work not only clarifies the excited state dynamical behavior of DHBO but also promotes the investigations about ESPT reactions in intramolecular or intermolecular hydrogen bonded chemical systems.
