Calibration graph of absorbance vs concentration
A new conjugated polymer PPV-PCN containing alternating alkoxy-substituted aromatic and cyano-substituted aromatic units was synthesized and characterized by NMR, FIR, GPC and TGA. The UV-vis absorption spectra and photoluminescence emission spectra in solution/films were characterized. The results indicate PPV-PCN has a smaller optical band gap va...
... molar extinction coefficient and mass extinction coefficient of PPV-PCN were also characterized. According to the Lambert-Beer law, four different concentrations of PPV-PCN were prepared. The k max = 350 nm was chosen to test the extinction coefficient. The calibration graph of absorbance versus concentration is shown in Fig. 3. The details are summarized in the Table 2. According to the Eq. ...
A hyperbranched porous polymer P based on adamantane and pyrene was synthesized through the Sonogashira coupling reaction. The three-dimensional rigid molecular skeleton of adamantane makes polymer P porous. Compound M, which acts as the block moiety between two adamantane groups in polymer P, was also synthesized for the control experiment. Compared with M, the characteristics of P changed remarkably with it exhibiting different emission behaviors and performances for the detection of DNT. In saturated DNT vapor, the quenching efficiency (ηEP) of film P (82%) was remarkably superior compared with that of film M (22%). In addition, a series of films with different thicknesses and different amounts of polymer P were prepared. Results showed that the quenching efficiencies did not change with an increase in the film thickness.
New monomers containing 4-cyanophenyl (–PhCN) groups attached to a thieno[3,2-b]thiophene (TT) or dithieno[3,2-b:2′,3′-d]thiophene (DTT) structure were synthesized and characterized as 4-(2,5-dibromothieno[3,2-b]thiophen-3-yl)benzonitrile (Br–TT–PhCN) or 4,4′-(2,6-dibromodithieno[3,2-b:2′,3′-d]thiophene-3,5-diyl)dibenzonitrile (Br–DTT–PhCN). The Suzuki coupling of 9,9-dioctylfluorene-2,7-diboronic acid bis(1,3-propanediol)ester and the Br–TT–PhCN or Br–DTT–PhCN monomer was utilized for the syntheses of novel copolymers poly{9,9-dioctylfluorene-2,7-diyl-alt-3-(4′-cyanophenyl)thieno[3,2-b]thiophene-2,5-diyl} (PFTT–PhCN) and poly{9,9-dioctylfluorene-2,7-diyl-alt-3,5-bis(4′-cyanophenyl)dithieno[3,2-b:2′,3′-d]thiophene-2,6-diyl} (PFDTT–PhCN), respectively. The photophysical, electrochemical, and electroluminescent (EL) properties of these novel copolymers were studied. Their photoluminescence (PL) exhibited the same emission maximum for both copolymers in solution. Red-shifted PL emissions were observed in the thin films. The PL emission maximum of PFTT–PhCN was more significantly redshifted than that of PFDTT–PhCN, indicating more pronounced excimer or aggregate formation in PFTT–PhCN. The ionization potential (HOMO level) and electron affinity (LUMO level) values were 5.54 and 2.81 eV, respectively, for PFTT–PhCN and were 5.57 and 2.92 eV, respectively, for PFDTT–PhCN. Polymer light-emitting diodes (LEDs) with copolymer active layers were fabricated and studied. Anomalous behavior and memory effects were observed from the current–voltage characteristics of the LEDs for both copolymers. © 2017 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.

Previous trial evidence suggested potential risk of serious urinary tract infections (UTIs) and genital infections in type 2 diabetes patients using sodium glucose co-transporter-2 inhibitors (SGLT2) inhibitors. We conducted a systematic review and meta-analysis to assess the effects of SGLT2 inhibitors on UTIs and genital infections in patients with type 2 diabetes. In total, 77 RCTs involving 50,820 participants were eligible. The meta-analyses of randomized controlled trials (RCTs) showed no… Expand
