Structure-Property Relationship on the Example of Gas Separation Characteristics of Poly(Arylene Ether Ketone)s and Poly(Diphenylene Phtalide). MEMBRANES 2021; 11:677. [PMID: 34564494 PMCID: PMC8465416 DOI: 10.3390/membranes11090677] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/26/2021] [Revised: 08/27/2021] [Accepted: 08/30/2021] [Indexed: 11/16/2022]
Abstract
Three poly(arylene ether ketone)s (PAEKs) with propylidene (C1, C2) and phtalide (C3) fragments, and one phtalide-containing polyarylene (C4), were synthesized. Their chemical structures were confirmed via 1H NMR, 13C NMR and 19F NMR spectroscopy. The polymers have shown a high glass transition temperature (>155 °C), excellent film-forming properties, and a high free volume for this polymer type. The influence of various functional groups in the structure of PAEKs was evaluated. Expectedly, due to higher free volume the introduction of hexafluoropropylidene group to PAEK resulted in higher increase of gas permeability in comparison with propylidene group. The substitution of the fluorine-containing group on a rigid phtalide moiety (C3) significantly increases glass transition temperature of the polymer while gas permeation slightly decreases. Finally, the removal of two ether groups from PAEK structure (C4) leads to a rigid polymer chain that is characterized by highest free volume, gas permeability and diffusion coefficients among the PAEKs under investigation. Methods of modified atomic (MAC) and bond (BC) contributions were applied to estimate gas permeation and diffusion. Both techniques showed reasonable predicted parameters for three polymers while a significant underestimation of gas transport parameters was observed for C4. Gas solubility coefficients for PAEKs were forecasted by "Short polymer chain surface based pre-diction" (SPCSBP) method. Results for all three prediction methods were compared with the ex-perimental data obtained in this work. Predicted parameters were in good agreement with ex-perimental data for phtalide-containing polymers (C3 and C4) while for propylidene-containing poly(arylene ether ketone)s they were overestimated due to a possible influence of propylidene fragment on indices of oligomeric chains. MAC and BC methods demonstrated better prediction power than SPCSBP method.

MAGNETIC RESONANCE IN CHEMISTRY : MRC 2021; 59:61-73. [PMID: 32702159 DOI: 10.1002/mrc.5079] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/04/2020] [Revised: 07/15/2020] [Accepted: 07/17/2020] [Indexed: 06/11/2023]
Abstract
All 13 C NMR signals of the poly(arylene) polymers, O-1, S-7, OS-4, OOS-3, OOOS-2, SSO-5, and SSSO-6 (where O is a diphenyleneoxiphthalide unit and S is a diphenylenethiophthalide unit) in dyads and triads were assigned unequivocally with two-dimensional NMR techniques (ge-2D [1 H-1 H] COSY, ge-2D [1 H-13 C] HSQC, and ge-2D [1 H-13 C] HMBC), and for each atom, the increments of the shifts are determined. For structurally similar carbon atoms of the phthalide cycle and heteroaromatic fragments of the skeletal chain, additive signal splitting schemes in phthalide centered dyads and in diphenylene oxide and in diphenylene sulfide centered triads are considered, based on taking into account the contributions to their shielding of adjacent and distant substituents. It was shown that the nature of the splitting of the signals of each of the 20 carbon atoms in 3,3-bisphenylphthalide fragments is determined by the type of carbon atom (tertiary or quaternary, even or odd), the type of heteroatoms in adjacent heteroaromatic fragments, their distance from the identified carbon nucleus, and their polyad symmetry. The results obtained in this article will greatly facilitate our further studies and, in particular, will allow us to study the microstructure of statistical copolymers based on the asymmetric OS monomer at the dyad and triad levels.

Additivity of retention of diastereoisomeric and enantiomeric arylphthalides, aryl(arylene)phthalides and aryldiphthalides of dyadic and triadic composition. J Chromatogr A 2020; 1630:461527. [PMID: 32956856 DOI: 10.1016/j.chroma.2020.461527] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2020] [Revised: 08/08/2020] [Accepted: 09/03/2020] [Indexed: 11/22/2022]
Abstract
For the first time, four series of new phthalide-containing heteroaromatic compounds were separated by reverse phase HPLC: OYO, OYS, SYS; OYOYO, OYOYS, SYOYS; SYSYS, SYSYO, OYSYO; OYYO, OYYS, SYYS, (where O - diphenyloxide, S - diphenylsulfide, Y - phthalide group). A fundamental difference was established in the chromatographic behavior of diaryl(arylene)diphthalides, built on the principle of "head-to-tail", and diaryldiphthalides with a structure of "head-to-head". The meso and chiral diastereoisomers of the former were eluted by one peak, while the latter existed in solution in the forms of stable cis (racemic form) and trans (meso form) rotamers with different retention times. It was shown that to calculate the retention times of related diarylphthalides, diaryl(arylene)phthalides, diastereoisomeric and enantiomeric diaryldiphthalides of an asymmetric structure, the half-sum rule can be applied according to which: tR(A-X-B)≈[(tR(A-X-A)+tR(B-X-B)]/2. For diaryl(arylene)diphthalides of a triadic structure, a modified additive scheme for calculating retention times is proposed, including multiplication and division operations: tR(A-A-A) = tR(A-A-B) × tR(A-B-B)/tR(B-B-B).
