    • Synthesis of P2: A mixture of 2-(2-bromoisobutylyoxy)ethyl methacrylate (27.9 g, 0.1mol, 2-(perfluorohexyl)ethyl methacrylate (43.2 g, 0.1mol, M-1620, Daikin Co, were dissolved in 166 g of 2-butanone and heated to 75 ° C in a nitrogen atmosphere. Subsequently, 0.345 g of dimethyl 2,2′-azobis(2-methylpropionate, V601, Wako Co, was slowly added, and the reaction mixture was further reacted at 75 ° C. After 12 h, the reaction mixture was cooled to room temperature and a solution of 50.2 g of 1,8-diazabicyclo[5.4.0]undecene-7 (DBU) and 0.23 g of 4-methoxyphenol in 2-butanone (100 g) was added to the reaction mixture and this was left to stir for 12 h at room temperature. After neutralizing with trifluoroacetic acid, the reaction mixture was poured into water and left for 30min with vigorous agitation. After drying under vacuum, a sticky white solid was obtained. 1HNMR (CDCl3, δ, 0.81.2 (m, 4H, 1.94 (m, 6H, 2.45 (t, 2H, 4.404.45 t, 6
    • w = 34700. P3 was obtained by polymerization of styrene and 2-hydroxyethyl methacrylate by V601, followed by condensation with 2-isocyanatoethyl methacrylate using bismuth octyric acid (U600 Nitto Kasei Co.) as a catalyst. P4 was synthesized by polymerization from 2-(perfluorohexyl)ethyl methacrylate and n-butyl methacrylate using V601.

    • Synthesis of A1: A mixture of 2.42 g of 4′-(10-undecenyl)-4, 2,6-bis(trichloromethyl)-1.3.5-tiazine-4-yl]}biphenyl, 0.9g of the trichlorosilane and 0.06 g of Speier's catalyst (10 wt% of H 2PtCl6/6H2O in isopropanol) in dry THF was stirred overnight at room temperature. When the reaction was complete according to 1HNMR, the solvent and the excess of trichlorosilane were removed under reduced pressure, leaving a slightly yellow solid, which was very sensitive to moisture and stored under Ar atmosphere. 1HNMR (CDCl3, δ, 1.21.-18 (m, 12H, 1.85 (qq, 2H, 2.0 (dt, 2H, 4.03 (t, 2H, 7.02 (d, 2H, 7.64 (d, 2H, 7.80 (d, 2H, 8.75 (d, 2H, HRMS (Bruker-Daltonics) calcd for C28H31Cl9N 3OSi [M, H, m/z 767.943, found. 767.943
