- Synthesis and properties of ion-conducting poly(anthrylacetylene) derivatives
-
Poly(anthryacetylenes) bearing oligooxyethylene units were synthesized from 10-ethynyl-9-[3,6-dioxaheptyl]oxycarbonylanthracene (1) and 10-ethynyl-9-[3,6,9,12-tetraoxatridecyl]oxycarbonyl-anthracene (2) by using a transition metal catalyst, WCl6, in 30% and 34% yields, respectively. Both of the polymers were black solids and soluble in chloroform, tetrahydrofuran, acetone, etc., but insoluble in alcohols, aliphatic hydrocarbons, etc. The UV-vis spectra of the polymers showed absorption maxima and band edges at around 570 and 750 nm, respectively, indicating that the polymer chains possess highly extended conjugation. These polymers exhibited blue emission (emission maxima ≈470 nm) upon photoexcitation at 380 nm. Poly(2) showed a fairly large ionic conductivity (4.1 × 10-5 S/cm) at 80 °C upon doping with Li(CF3SO2)2N.

- Novel synthesis method for 5-[10-(9-carbosyl anthryl)]-isophthalic acid
-
The invention provides a novel synthesis method for 5-[10-(9-carbosyl anthryl)]-isophthalic acid. A diazotization bromination reaction is conducted on 5-amino-1,3-benzenedicarboxylic acid dimethyl ester to synthesize a compound A, namely, 5-bromine-1,3-benzenedicarboxylic acid dimethyl ester, and catalysts are added to 5-bromine-1,3-benzenedicarboxylic acid dimethyl ester under the condition of nitrogen protection to make 5-bromine-1,3-benzenedicarboxylic acid dimethyl ester react with bis(pinacolato)diboron so as to generate a compound B, namely, 3,5-bis(methoxycarbonylethyl)phenylboronic acid pinacol ester. In addition, anthracene-9-carboxylic acid is bromized to obtain a compound C, namely, 10-bromine-9-carboxylic acid, the compound C is subjected to methyl esterification to generate a compound D, namely, 10-bromine-9-anthracene methyl formate, and the compound D and the compound B are subjected to a nitrogen protection reaction under the effect of catalysts to generate a compound E, namely, 5-[10-(9-methoxycarbonyl group anthryl)]-benzenedicarboxylic acid dimethyl ester, and a target compound F, namely, 5-[10-(9-carboxyl anthryl)]-isophthalic acid through a hydrolysis reaction. The target compound F is shown in the figure.

- Solution processed ter-anthrylene-ethynylenes for annealing-activated organic field-effect transistors: A structure-performance correlation study
-
OFETs based on new solution-processed ester functionalized 9,10-ter-anthrylene-ethynylenes show a mobility increase of four orders of magnitude, leading to mobilities as high as 4.9 × 10-2 cm 2 V-1 s-1 if the deposited film is annealed before contact deposition. The behavior is ascribed to an increase in film order at the dielectric/semiconductor interface as revealed by X-ray studies.

- Fluorescence properties of derivatives of anthroic acids
-
Fluorescence behaviour of 9-anthracenecarboxylic acid (H-ANCOOH), 10-bromoanthracene-9-carboxylic acid (Br-ANCOOH) and 10-cyanoanthracene-9- carboxylic acid (CN-ANCOOH) in solvents of different polarities was investigated, using the steady state and time-resolved methods. The dual fluorescence of the acids originates clearly from the fluorescence of the undissociated acids and the anions. From the ground-state absorptiometric titration the pKa values have been obtained, whereas for the values of pKa in the excited singlet state (pKa.) the Foerster cycle was used. Introduction of the electron withdrawing groups (Br and CN) shifts the pKa values both in the ground and singlet excited states to the lower values compared to the parent molecule. On the other hand, the presence of the electron accepting groups in anthracene moiety influences the spectral position of the bimolecular exciplexes (excited state complexes) formed between the excited acids and the electron donor molecule, such as p-cyano, N,N-dimethylaniline (DMABN) in nonpolar solvents. A correlation between the decreasing pKa values in the excited singlet state and the position of the charge transfer luminescence of the intermolecular exciplexes has been found.
