Nova, Nabila Nabi;Zarzar, Lauren D. research published 《 Direct laser writing of graphitic carbon from liquid precursors》, the research content is summarized as follows. One-step synthesis and micropatterning of different types of carbon nanomaterials, such as amorphous carbon or three-dimensional graphene which have versatile electrochem., thermal, and mech. properties, are advantageous for the fabrication of microelectronics, sensors, and wearable devices. Here, we report a direct laser writing method to simultaneously synthesize and pattern graphitic carbon from liquid organic precursors. We have tested a wide range of liquid organic precursors and identified the chem. characteristics that are beneficial for successful laser-induced solvothermal deposition. The laser-deposited carbon exhibits a paracryst.-to-polycrystalline structure and has elec. resistivities on the order of 10^-3 to 10^-4 Ω m which is tunable through variations in the laser power. Such properties of the laser-deposited carbon, coupled with the ability to direct-write custom patterns with microscale resolution, make these carbon materials exciting candidates for use in applications such as energy storage and sensing.

Ohira, Kazuki;Imato, Keiichi;Ooyama, Yousuke research published 《 Development of phenazine-2,3-diol-based photosensitizers: effect of formyl groups on singlet oxygen generation》, the research content is summarized as follows. Phenazine-2,3-diol derivatives KO-0-3, which have zero to three formyl groups, resp., have been developed as photosensitizers (PSs) possessing the ability to generate singlet oxygen (1O2). The photoabsorption bands of KO-0-3 are significantly red-shifted compared to those of phenazine-2,3-MOM (methoxymethyl) derivatives 5-8, whose hydroxy and formyl groups are protected, and have onsets at around 600-650 nm. Furthermore, the fluorescence quantum yields (Φfl) of KO-0-3 (Φfl = 0.024-0.097) are lower than those of 5-8 (Φfl = 0.34-0.46) in solution To gain insight into the 1O2 generation properties of KO-0-3, we evaluated the 1O2 quantum yields (ΦΔ) and rate constants (kobs), and demonstrated that KO-1-3 possess a higher ability to generate 1O2 under visible light irradiation than those of 5-8. Moreover, it was found that the ΦΔ values of KO-0-3 increase in the order of KO-0 (0.036) < KO-1 (0.22) < KO-2 (0.33) < KO-3 (0.41) with increasing number of formyl groups. This result indicates that formyl groups facilitate the intersystem crossing (ISC) from the lowest singlet excited states of the PSs (S1) to the triplet excited states (Tn) according to El-Sayed′s rule. Consequently, this work provides useful knowledge in mol. design of efficient phenazine-2,3-diol-based PSs for photodynamic therapy (PDT).

Ontiveros, Jesus F.;Hong, Bing;Aramaki, Kenji;Pierlot, Christel;Aubry, Jean-Marie;Nardello-Rataj, Veronique research published 《 Cation Effect on the Binary and Ternary Phase Behaviors of Double-Tailed Methanesulfonate Amphiphiles》, the research content is summarized as follows. A series of sym. dialkyl methanesulfonate amphiphiles [DiC_nCHSO₃]_mM (n = 6, 7, 8) with different counter cations (M^m+ = H⁺, Li⁺, Na⁺, K⁺, Cu⁺², Zn²⁺, Mg²⁺, Ca²⁺, Sc³⁺) were synthesized in five steps. Their solubility and critical micelle concentration (CMC) in water were determined highlighting a huge effect of the chain length and the nature of the cation. The hydrophilic-lipophilic balance of the surfactants were assessed with the phase inversion temperature (PIT)-slope method based on the deviation from the PIT of the reference C₁₀E₄/n-octane/0.01 M NaCl_(aq) emulsion through addition of increasing amounts of the dialkyl methanesulfonates. The hydrophilicity of the surfactants was thus ranked in terms of dPIT/dx_sulfonate. A “cation” scan with the [DiC₆CHSO₃]_mM/benzene/water systems at f_w = 0.5 was finally performed confirming the hydrophilicity ranking obtained with the PIT-slope method. It revealed that the [DiC₆CHSO₃]₂Mg behaves as a “Balanced Surfactant” able to form spontaneously a three-phase microemulsion system (Winsor III) just in the presence of water and oil, in the same way as the catalytic surfactant dimethyldioctylammonium molybdate, which has the same PIT-slope.

Otep, Sultan;Tseng, Yu-Cheng;Yomogita, Naomasa;Chang, Jia-Fu;Chueh, Chu-Chen;Michinobu, Tsuyoshi research published 《 Coil-rod-coil triblock copolymers synthesized by macromolecular clicking and their compatibilizer effects in all-polymer solar cells》, the research content is summarized as follows. Poly(diethynylthiophene) (PDET) synthesized via Hay coupling polycondensation retains terminal alkynes for tethering polystyrene (PS) blocks by a simple Cu-catalyzed azide-alkyne click (CuAAC) reaction. The successful synthesis of triblock copolymers was confirmed by ¹H NMR, FTIR, and GPC measurements. Optical and electrochem. properties of the PDET block were conserved in the triblock copolymers, as determined from the UV-vis absorption spectra and redox potentials. Surface topog. of the polymer films revealed the micrometer-scale features attributable to phase separation, which was supported by thermal analyses. The compatibilizer functions of PDET and triblock copolymer P1 were investigated and compared in all-polymer solar cells (all-PSCs). Addition of 1 wt% P1 was shown to result in an enhanced power conversion efficiency (PCE) from 5.90% to 6.24%, corresponding to a relative increase of ∼6%, whereas the addition of 1 wt% PDET decreased the resultant PCE. Notably, adding a proper compatibilizer helped reduce the device’s potential loss, as evidenced by the improved V_oc in the 1 wt% P1 device. Our results highlight the critical role of the coil segment in designing block copolymer-based compatibilizers for all-PSCs. Also, this study demonstrates a straightforward synthetic route for coil-rod-coil triblock copolymers that afford a compatibilizer function suitable for all-PSCs.
