Karstedt catalyst

Octakis(hydridodimethylsiloxy)octasilsesquioxane was supplied by PIW Unisil Sp. z o.o., Tarnów, Poland, and 9,10-dihydro-9-oxa-10-phosphahenanthrene-10-oxide (DOPO) (>97%) was purchased from TCI Deutschland GmbH, Eschborn, Germany. Chloroform-d, allyl glycidyl ether (≥99%), and Karstedt catalyst (2% Pt in xylenes) were purchased from Sigma-Aldrich Sp. z o.o, Poznań, Poland. Acetone, tetrahydrofuran (THF), and toluene (all purities were suitable for analysis) were purchased from POCH, Gliwice, Poland. Hydrogen peroxide (30%) was purchased from ChemPur, Piekary Śląskie, Poland. Epoxy resin Epidian 652 (E652) and isophoronediamine (IDA) as a hardener were purchased from Ciech Resins, Nowa Sarzyna, Poland. All reagents were used without further purification.

All commercially available chemicals were used as received without any further purification. 1,1,1,3,5,5,5-heptamethyltrisiloxane was purchased from Sigma-Aldrich (St. Louis, MO, USA). Allyl polyether was purchased from ICSO Chemical Production (Kędzierzyn-Koźle, Poland). The hydrosilylation catalyst was a commercially available Karstedt catalyst purchased from Sigma-Aldrich.
Doubly distilled and deionized water (Destamat Bi18E, Heraeus, Hanau, Germany) was used for 3-[3-(hydroxy)(polyethoxy)propyl]-1,1,1,3,5,5,5-heptamethyltrisiloxane) (TS-EO12) solutions preparation. Pyrene (Py, purity > 99%) was purchased from Sigma-Aldrich and used without further purification. Ethanol (EtOH) for the Pyrene stock solutions preparation was purchased from Avantor Performance Materials Poland S.A. (Gliwice, Poland). The ethanol stock solution of Pyrene as well as aqueous stock solutions of TS-EO12 of the appropriate concentrations were prepared by weighing using an analytical balance (model XA105, Mettler-Toledo, Columbus, OH, USA). All the aqueous solutions at a given surfactant concentration lower than that at the stock solution were prepared by dilution of the appropriate stock solution. The Pyrene concentration in the stock ethanol solution and in the surfactant solution was equal to 1 × 10⁻² mol/dm3 and 2 × 10⁻⁶ mol/dm³, respectively.
